They still manage to defeat the Mutants, but crash the Thundertank. Lion-O realizes that this must be Mumm-Ra's evil work and goes to the pyramid to stop Mumm-Ra. Meanwhile Cats Lair is getting worse as Cheetara and Tygra rush to fix things in the lair but are attacked by the Lunataks.

But when she and Lynx-O go to Darkside to capture Chilla, they fall into one of the Lunataks' traps. It seems that the Lunataks wanted the Braille board so that the ThunderCats could not get to them. But when the board dissappears, they try to get the information from Lynx-O as to where it went, but Mandora escapes and frees Lynx-O.

RUNAWAYS

But Mumm-Ra has been observing the situation and disguises himself as Cudi to gain entrance to the Lair.

HAIR OF THE DOG
With only Lion-O and Snarf guarding the Lair, Mumm-Ra decides this is a perfect opportunity to invade the Lair, so Ma-Mutt captures Snarf and Mumm-Ra switches Snarf and Ma-Mutt. Ma-Mutt (who now looks like Snarf) goes to Cats Lair and gives Lion-O some poisoned candy fruit. Lion-O becomes ill and realizes that this Snarf is really Ma-Mutt and Mumm-Ra arrives and defeats Lion-O.

He sends Ma-Mutt to get Snarfer and Lion-O becomes better again and distracts Mumm-Ra. When Lion-O summons the other ThunderCats, Snarf (who looks like Ma-Mutt now), using Mumm-Ra's chant that changes Mumm-Ra into the everliving, becomes...

THE TOTEM OF DERA
Mumm-Ra finds the Totem of Dera (a part of the T-Cat treasure) which has special healing powers and can bring inanimate objects to life. He gives it to Vulture-Man and the Mutants so they can make a device to destroy the T-Cats. After making the device, the mutants decide to test it near a swamp. At Cat's Lair, Lion-O sees that there is some mutant activity near the swamp. He, Wilykit, and Snarfer decide to check it out. When going to the swamp, the HoverCat is brought down by a swamp monster made by the device. The HoverCat crashes in the swamp, and Lion-O gets intoxiCated by the deadly swamp water.

THE CHAIN OF LOYALTY
After looking at the Book of Omens, and seeing a picture of a necklace, Lion-O discovers that there are pictures of the ThunderCats on the necklace. Jaga appears to Lion-O and tells him that he is looking at a picture of the Chain of Loyalty. Jaga tells Lion-O that if the chain gets broken, it would cause the ThunderCats to turn against each other. In hearing this, Lion-O and the ThunderCats (Panthro, Tygra, Cheetara, and the Thunderkittens) set off to Thundera to find the chain. Mumm-Ra, eavesdropping on Lion-O through his pool at the pyramid, goes to Thundera, kidnaps and disguises himself as Snarf. When the ThunderCats arrive, they split up into groups to find the chain, and Mumm-Ra goes with Lion-O and the Thunderkittens. Lion-O's group finds the chain and Mumm-Ra gets it, breaks it, and returns to his true form.

Mumm-Ra is defeated and the ThunderCats return to Third Earth.

CRYSTAL CANYON
Lion-O, Lynx-O, Snarf and Tygra go to the Crystal Canyon, thinking the Lunataks somehow got the Treasure of Thundera. While there, they encounter Aluro and Chilla.

Lynx-O is seriously injured and Lion-O is knocked unconscious. Tygra and Snarf find the Keystone and when Tygra holds the Keystone, he becomes convinced that it is making him more powerful. He uses it to restore the Thunderstrike, and heal Lion-O and Lynx-O. They return to the Lair and the other 3 ThunderCats learn Tygra has become seriously addicted to the Keystone. When they try to tell Tygra he's become a slave to the Keystone, he doesn't believe them. Later in a battle against Aluro, Tygra thinks he's invincible, but Aluro proves him wrong and takes the Keystone from Tygra. Then Aluro himself becomes addicted to the Keystone.

Meanwhile, the Lunataks enslave Panthro with a mind control device, and tell him to make the Sky-Tomb able to fly to Thundera. When the ThunderCats are looking for Panthro, Vultureman makes Cheetara see images of him being captured by Mumm-Ra, being stuck on Hook Mt., and being held at Castle Plundarr. Lion-O goes to Mumm-Ra's pyramid, and is ambushed by Luna and Amok, who capture him. Tygra goes to Plundarr and is captured by Red Eye. The Thunderkittens also get captured on Hook Mountain. Cheetara is about to go crazy, but Lynx-O tells her to listen to her heart instead of her mind. She turns into a huge ball of energy that shoots out and destroys Vultureman's device and frees Panthro and the other ThunderCats.

EXILE ISLE
The ThunderCats capture the Lunataks and, tired of dealing with their evil ways, decide to exile the Lunataks to Exile Isle, an island in space far away from Third Earth. When the Lunataks arrive, they meet up with Captain Cracker, a pirate who the ThunderCats also exiled. Together, the Lunataks and Capt. Cracker send out a distress signal to a passing ship. When the ship comes near the island, the Lunataks send up a cloud of fog, which makes the ship crash. They use the engines of the ship to push the planet out of orbit and towards Third Earth. Snarfer, on his way home from Thundera, crashes on the island when it runs into him. Lion-O goes to rescue Snarfer and stop the island, because it has a deadly gas that will blow up if it enters Third Earth's atmosphere. He goes without the Sword of Omens. He gets cornered by Capt. Cracker, but the Sword awakens and flies to Lion-O, without him even calling it. He then uses dirt to stop the engines, and the planet/island eventually returns to orbit. The Lunataks, still stuck there, turn Capt. Cracker's house into a ship and fly back to Third Earth.

KEY OF THUNDERA
While trying to figure out a way to read the Book of Omens, Lion-O tries looking through the sword at the book. He is immediately drawn into the book, where a voice asks him if he has "the key." Lion-O says he doesn't, and four dragon heads appear and shoot fire at him. Snarf, who saw Lion-O get sucked into the book, tries to show Cheetara what happened, and he too gets sucked in. Mumm-Ra, who also watched Lion-O get sucked in, goes to Cats lair and takes the book so he can destroy it with Lion-O inside. Meanwhile, just by coincidence, Panthro finds an odd looking key on Thundera. He and Tygra head back to Third Earth with the key, not knowing what it's for. Back on Third Earth, Mumm-Ra is just about to boil the book when Lion-O calls for the sword, and it brings him and Snarf back outside. Mumm-Ra takes the sword and looks through it at the book, and he gets sucked in! But Lion-O has to save him because of the code of Thundera, and Lion-O does save him. Panthro and Tygra arrive with the key, and they realize it is the one the book was asking for.

RETURN OF THE THUNDERCUBS
Panthro, Tygra, and Cheetara return to New Thundera in the Feliner to find more of the Treasure of Thundera, but Mumm-Ra shoots the Feliner down and, as the Fog of Despair, sends them to the Canyons of Youth, which changes them back into Thundercubs. Then Mumm-Ra disguises himself as Lion-O and tells the Thundercubs to find the treasure for him. Meanwhile, back on Third Earth, Lion-O and Snarf decide to go rescue the ThunderCats on New Thundera, but they must ask the Mutants to take them to New Thundera in the Rat-Star. The Mutants agree, secretly planning to attack Lion-O once they're in space. They do attack and imprison him and Snarf on the way to Thundera, but they manage to break out. Cheetara meanwhile, using her sixth sense, loCates part of the treasure, the Mirror of Truth. The real Lion-O shows up, and uses the Sword of Omens with the Mirror of Truth to restore the cubs to their proper age, and Mumm-Ra reveals himself and turns into Mumm-Ra the everliving. Cheetara uses the mirror to defeat Mumm-Ra. Finally, the ThunderCats use the Rat-Star's supplies to fix the Feliner, and then go home with the Mutants wedged in the baggage compartment.

THE FORMULA
Aluro invents a "booster" potion in hopes that it can make Sky Tomb able to fly to Thundera. It doesn't work, and he throws the potion into the forest. Then he notices everything in the forest has grown huge. He and Luna give the potion to the Mutants, who sprinkle it around Cats Lair. The Mutants also capture Lynx-O and Snarf. But while the Mutants are preparing to transfer Lynx-O and Snarf from their cell, a mouse in the cell who Snarf had befriended gets some of the potion and attacks the Mutants. That lets Lynx-O and Snarf analyze the potion and come up with an antidote. Meanwhile, Lion-O, Pumyra, and the Thunderkittens are fighting off huge bugs in the forest that has grown around Cats Lair. Lynx-O and Snarf arrive, sprinkle the antidote over the forest, and then watch as everything turns back to normal.

LOCKET OF LIES
On Thundera, Mumm-Ra creates the Locket of Lies and has Mu-Mutt plant it in the Valley of the Snarfs. Eggbert and Oswald Snarf find the locket and contact the ThunderCats about it. When communiCations break up, the ThunderCats (Lion-O, Cheetara, Panthro, Tygra) go to Thundera to see the Locket. When they arrive, the Locket leads them to a place in front of an old building. But the ground they are standing on gives way and they are trapped in a well. Mumm-Ra shows up and tells them not to try to escape, but the ThunderCats try anyway. The walls start closing on them, and all their efforts to stop the walls fail. Finally, Lion-O uses the Eye of Thundera and the Cat Signal to push through the wall, and they all escape.

BRACELET OF POWER
few more pieces of the Treasure of Thundera. Snarf is fascinated by a bracelet and takes it to wear around. He sees that everyone obeys his every command when he has on the bracelet. Mumm-Ra also notices this. He goes to Cats Lair, takes the bracelet, and turns Lion-O, Cheetara, Tygra, and Panthro into his slaves. He takes them to his pyramid and locks them in a cell. Snarf and the Thunderkittens decide to go rescue the ThunderCats. At the pyramid, when Snarf encounters Mumm-Ra, Snarf acts like the bracelet is controlling him, but he is actually immune to the bracelet's power. Meanwhile, the Thunderkittens take back the Sword of Omens, which Mumm-Ra had taken. Mumm-Ra, now trusting Snarf, goes to sleep in his casket, and Snarf takes the bracelet back. The spell is broken and the ThunderCats escape from the cell. Mumm-Ra confronts them, but Lion-O uses the Sword to lock Mumm-Ra in the cell.

THE WILD WORKOUT
Lion-O, Panthro, and Snarf set out to look for more pieces of the Treasure of Thundera, and Mumm-Ra sets a trap for them using Thunder Catnip. He freezes them in the caverns of cold on Thundera. Meanwhile, back on third earth, the Lunataks, in need of another source of power for their ship, use excersise machines to power it up. They capture Cheetara, and then Tygra and the Thunderkittens and force them to work out on the machines to power up the ship. The ThunderCats manage to overwork the power supply, and escape from Sky Tomb. Back in the caverns, Snarf manages to get the sword of omens to Lion-O with his tail, and they escape and return to third earth.

THE THUNDERSCOPE
Back visiting their old wreckage site, Lion-O and Snarf find the Thunderscope, a legendary Thunderian telescope that loCates lost Thunderians, as well as pieces of the Treasure of Thundera. Mumm-Ra decides to try and steal the Thunderscope so he can use it to find the Treasure. He ambushes Lion-O, and actualy kills him. Before Lion-O dies, he manages to take out a lens from the Thunderscope so Mumm-Ra cannot completely use it. Jaga appears and revives Lion-O's dead body, as well as the Sword of Omens which had been damaged. Mumm-Ra realizes a lens is missing, and comes back with Chilla and Tugmug to fight Lion-O for it. Mumm-Ra gets the lens and goes back to his pyramid, but Lynx-O sends out an energy beam that blocks the Thunderscope from working. This lets Lion-O get to the pyramid in time to fight Mumm-Ra again. This time Lion-O gets the Thunderscope by defeating Mumm-Ra with a blast from the eye of the ThunderCat signal.

THE JADE DRAGON
Mumm-Ra discovers the power of one of the pieces of the treasure of Thundera. The Double-Headed Dragon of Doom, or the Jade Dragon possess the power to entrap people in its stomach. The legend says that Hachiman's ancestor gave the dragon to his wife as a marriage gift, and since her father was so against their marriage, he put a curse on the dragon and it engulfed Hachiman's ancestor. Jaga freed him though, and he gave the dragon to Jaga for safe keeping. Now, the ThunderCats have found the Jade Dragon, and Mumm-Ra manages to trap Lion-O and Cheetara in it. Hachiman is their only hope. He battles Mumm-Ra in Mumm-Ra's Pyramid, and the statues of the ancient spirits of evil come alive to fight Hachiman. He destroys the statues, thus making Mumm-Ra weak, and enabling Hachiman to free Lion-O and Cheetara from the Dragon with a swipe of his sword.

THE CIRCUS TRAIN
A bounty hunter known as Captain Bragg comes to Third Earth to help the ThunderCats get rid of the Mutants and the Lunatacks. Capt Bragg tricks Wilykat in going with him and they first go after the Mutants. After capturing them, they go to capture the Lunataks. They capture all except Luna and Amuk, who free the other Lunataks, put Bragg in a cage and tie Wilykat to the train's engine. Lion-O and Wilykit arrive to save Wilykat and the Lunataks are defeated. All the Mutants and all the Lunataks are captured and exiled.

THE LAST DAY
With the Mutants and Lunataks gone, the Ancient Spirits of Evil give Mumm-Ra until sunset to destroy all the ThunderCats, and to prove they're not bluffing, they exile Ma-Mutt. Mumm-Ra spreads destruction all over Third Earth, sends Tygra, Cheetara, and Panthro to limbo, and buries Lion-O alive. Then he attacks and destroys the Tower of Omens, and the Thunderkittens barely escape, but Mumm-Ra sends them to limbo too. Snarf must go into the Book of Omens to find out how to defeat Mumm-Ra. Jaga and the ThunderCats in limbo go into the Eye of Thundera to help Lion-O free himself from his rocky prison. Lion-O then battles Mumm-Ra at Cats Lair and finds out from Snarf that Mumm-Ra only has until sunset to defeat the ThunderCats. Mumm-Ra fails and the Ancient Spirits of Evil banish and exile Mumm-Ra from Third Earth. With all their enemies gone, the ThunderCats decide to permanently return to New Thundera.

RETURN TO THUNDERA!: PART I
The Ancient Spirits of Evil give new life to Mumm-Ra and Ma-Mutt, send them to New Thundera, and build a new Pyramid for Mumm-Ra. The ThunderCats say goodbye to Third Earth and depart for Thundera, leaving Tygra and Pumyra behind to watch Cat's Lair and the Tower of Omens. The ThunderCats soon arrive and begin plans to build a new lair. Mumm-Ra meanwhile learns that the planet's gravity is controled by the Gyroscope under the Churning Rocks at the center of the planet. The Gyroscope is guarded by Jaguara, an ancient ThunderCat sorceress. Mumm-Ra disguises himself as Jaga and puts Jaguara under a spell, making her change the rotation of the Gyroscope to throw the ThunderCats clear off the planet. As the ThunderCats are floating away, Lion-O calls on the Eye of Thundera to help him, and it breaks Mumm-Ra's spell... but not before Mumm-Ra takes part of the Gyroscope's regulator. Without those controls, the planet will be destroyed within 2 hours...

RETURN TO THUNDERA!: PART II
More and more earthquakes are ocurring because of the malfunctioning Gyroscope. Meanwhile Lion-O recieves a distress signal from Thunderian refugees, and he, Cheetara, and Snarf go to find them. Mumm-Ra resurrects Grune the Destroyer, and Grune seeks out Lion-O and Cheetara. Grune finds and fights them, breaks the Sword of Omens, and then he chains them up on the Churning Rocks. Snarf, who was hiding, gathers the pieces of the Sword to take back to Bengali to be fixed. Snarf gets captured by Char, a theif who wants the Sword for himself. Snarf tricks him into reforging the Sword, and when it is as good as new, Lion-O begins to sense it, and so he calls it. The Sword goes to him, he escapes, and then he defeats Grune. But Mumm-Ra still has the Gyroscope's regulator.

RETURN TO THUNDERA!: PART III
Lion-O, Panthro, and the Thunderkittens take the Whisker, a new flying vehicle, to the Churning Rocks to rescue the Thunderian refugees who had called from there. The ThunderCats get captured by Two-Time, a robot with 2 heads. Two-Time takes them aboard his spaceship, Dome-Down, and the ThunderCats see that he has also captured the refugees. Lion-O defeats Two-Time and the refugees are freed. Meanwhile, Lynx-O, Cheetara, and Bengali spot Mumm-Ra near the Churning Rocks, and inform Lion-O of this. Lion-O, Panthro, and the Thundekittens head to the Churning Rocks and confront Mumm-Ra, who is in the form of Jaga again. They break Mumm-Ra's spell (again) over Jaguara, who had temporarily repaired the Gyroscope. Lion-O defeats Mumm-Ra, but Mumm-Ra reminds them all that eventually the planet will be destroyed without the real controls, which he still has.

RETURN TO THUNDERA!: PART IV
Mumm-Ra sends Ma-Mutt disguised as Mandora to free the Mutants from Capt. Bragg's circus train and sends Bragg and Crowman falling into deep space. The Mutants are then ordered by Mumm-Ra to get rid of Tygra and Pumyra. The Mutants attack Snowman on Hook Mt. and Snowmeyow gets Pumyra for help and Tygra contacts the real Mandora to save Bragg and Crowman. Then together, they recapture the Mutants. Meanwhile on New Thundera, the earthquake tremors grow worse and the new Cats Lair collapses trapping Snarf in the ruins. Lion-O uses the sword to contact the other ThunderCats and they rush to the Lair to save Snarf. Afterwards, Mumm-Ra destroys the Gyroscope's regulator.

RETURN TO THUNDERA!: PART V
After another earthquake caused by Mumm-Ra ruins the new Cats Lair construction site, the ThunderCats go to see Jaguara and confront Mumm-Ra. Unfortunately, Mumm-Ra puts up a force field over entrance. Jaga appears to Lion-O and tells him to use the Eye of Thundera to get to Jaguara and the Gyroscope. Lion-O does so and battles Mumm-Ra, who throws him into the bottomless pit underneath the Gyroscope. Lion-O however, manages to throw his grappling hook to the top, which pulls him back up. Lion-O then shines the signal, which goes through the force field. All the ThunderCats leap through the signal which takes them through the force field. Together, they fire all their weapons at Mumm-Ra and he is defeated. But before he leaves, he breaks the cord that holds the Gyroscope above the pit and it falls through. Now, New Thundera is literally falling apart. But Lion-O throws the sword in the spot where the Gyroscope used to be and calls upon the ThunderCat Ancestors for help. The sword starts spinning and creates a new Gyroscope, thus the planet is saved.

LEAH
The Ancient Spirits of Evil bring the Mirror Rape to Mumm-Ra, and he disguises it as a child's toy. Mumm-Ra then intercepts a thunderian escape pod which carries in it a little girl. He gives the toy to the child (Leah), and leaves. She is rescued by the ThunderCats, and goes into New Cat's Lair with the doll. The doll turns into the Mirror Rape when left alone, and begins to destroy Cat's Lair, and the ThunderCats have no clue where the evil Mirror Rape came from.

FROGMAN
Wily Kit and Kat are constructing a well for the New Cat's Lair on New Thundera. The ThunderCats on New Thundera receive a distress signal from Thunderian refugees trying to find their way to New Thundera. The Kittens are left alone with Snarf on at the New Cat's Lair, and Lion-O and Snarfer are out constructing an early warning device (I guess for weather purposes). The rest of the ThunderCats seek out the refugees in space. When Wily Kit and Kat strike water, they accidentally unleash a monster that Jaga trapped in the underground lake centuries ago. Frogman, with aquatic powers, tries to sink the New Cats Lair. Lion-O however re-traps Frogman in his watery prison.

THE HERITAGE
Wily Kit and Kat, exploring New Thundera, stumble upon an Orb of Gold, and pick it up thinking that it is apart of their Heritage. Possessed by the power of the Golden Sphere of City, the ThunderKittens get greedy, and let the power of the orb overcome them. Mumm-Ra manages to get a hold of the orb, and his powers get four times more powerful. He gets so powerful, he destroys the Sword of Omens. Jar, the scrap metal collector reforges it for Lion-O. He gets so powerful that he challenges the power of the ancient spirits of evil. They lock him out of his pyramid until he surrenders the Orb to them. The spirits of evil let him back in, but destroy the Golden Sphere of City.

SCREW LOOSE
The ThunderCats call on a robot named Screw Loose to help the weary Jaguara with running the Gyroscope. Mumm-Ra replaces Screw Losse's brain system with a bad system, and Screw Loose goes crazy and tries to destroy the Gyroscope. Lion-O uses the Sword to fix Screw Loose and then Screw Loose actually helps to defeat Mumm-Ra. Now Jaguara has someone to help her permanently run the Gyroscope.

MALCAR
Mumm-Ra summons Malcar, an ancient alchemist, to return from the dead. The alchemist returns old and weak, as he was when he died. Mumm-Ra takes him to the canyons of youth to restore his youth and power. Malcar regains his powers, and uses them against the ThunderCats. He transforms all the Thunderillium on the planet into Thundrainium.

HELPLESS LAUGHTER
A convergence of the Moons of Plun-Darr causes a drought on Thundera. Panthro and Snarf go looking for water, then Ezuka, the flying Serpent of Dreary Canal wanting to get water itself, attacks Panthro and Snarf and causes them to fall into the Swamp of the Laughing Lilypads, making them laugh out of control. Ezuka attacks the Lair, still looking for water. Lion-O uses the Sword to make some rain, then he and Ben-Gali use the Thunderstrike to melt some ice, but Mumm-Ra comes along and causes a flood. Lion-O calls for the others, which also free Panthro and Snarf from the laughter and they use some of the Swamps water to cause Mumm-Ra to laugh uncontrolably, and he falls in the flood waters and is washed away.

CRACKER'S REVENGE
Capt. Cracker and his mechanical parrot Polly land on Way-Out Back and free the Lunatacs and put Bragg and Crownan in one of the train's cages. They plan to go to Third Earth to attack it since most of the ThunderCats are no longer on Third Earth. Meanwhile the ThunderCats have learned Cracker escaped and Snarfer and Mandora go to Catch him. Bragg has Crownan ride a fire exstiquisher, so he can get into space and get help. Mandora finds him, and the three of them go to Third Earth. Mandora fights with Cracker and the Lunatacs, but is beaten and she and Snarfer are tied to her cycle and sent towards a mountain. Lion-O, Panthro, and Cheetara arrive and Lion-O saves Mandora and the others. Meanwhile Cracker and the Lunatacs go to attack Cats Lair, only occupied by Pumyra, but Lion-O uses the Eye's signal to cause the drawbridge to tilt, sending Cracker and the Lunatacs into the moat. The Lunatacs are exiled again.

THE MOSSLAND MONSTER
Tygra, on a solo trip to New Thundera to meet the other ThunderCats, decides to take a shortcut through a meteor shower. His ship is damaged, and he lands on an unexplored region of New Thundera. The MosLand. It turns out that the moss in mosland is part of a giant monster who captures Tygra with its moss. Lion-O, Bengali, Snarf, and Snarfer set out to save Tygra and battle the Moss Monster.

MA-MUTT'S CONFUSION
Mumm-Ra has a new device, the Babylonian Barbarian Boiler, that he plans to use on Cats Lair. Ma-Mutt fools around too much and Mumm-Ra banishes him from the Pyramid. Later, the Thunderkittens, Snarf, and Snarfer bring Ma-Mutt back to Cats Lair and then Mumm-Ra fires the Boiler's beam at the Lair, which causes it to start melting. Snarfer makes a communiCating device (because Ma-Mutt was trying to tell them about the beam), so they can understand Ma-Mutt. Ma-Mutt starts telling them of the Boiler, but Mumm-Ra sees this and through the Cauldron's magic brings Ma-Mutt back to the Pyramid. Then the ThunderCats construct a giant Light-Shield and use it to protect the Lair, but Mumm-Ra just boosts the power on the Boiler, destroying the Shield. Lion-O uses the Cat Signal to push back the beam, which causes the Boiler to explode, and the Signal restores Cats Lair. Mumm-Ra, who was lonely without Ma-Mutt, welcomes his dog back to the pyramid.

THE SHADOWMASTER
From the Shadow Realm, the Shadowmaster contacts the Ancient Spirits of Evil (ASOE), telling them of how he captured Lion-O's father, Claudus, just before Thundera blew up. Then the Shadowmaster, through a bad dream, shows Lion-O his captured father and challenges Lion-O to a fight. Lion-O goes to the Shadow Realm through the Book and Sword of Omens, and is able to fight the Shadowmaster as long as the Sword stays bonded to the book. However, the Shadowmaster sends a huge bat to steal the Sword. It succeeds, and then Lion-O becomes very weak in the Shadow Realm. Mumm-Ra meanwhile, feeling like the ASOE will turn against him in favor of the Shadowmaster, sends Ma-Mutt to secretly steal the sword from the bat and put it back near the book. This renews Lion-O's strength, who calls for the Sword, rescues Claudus, and exiles the Shadowmaster. Claudus leaves Lion-O, but at the end you see him and Jaga standing next to each other in that blue, ghostly form. Now Lion-O has 2 mentors to give him advice!

SWAN SONG
An Ecology Inspector (EI) comes to Thundera to inspect the new Cats Lair. His ship uses the SWAN system (Space Way Airborn Navigations) to direct him to planets all over the universe. When he arrives on Thundera, he gets ambushed by Two-Time (see Return to Thundera, Part III, this page). Two-Time uses a hologram to make the EI's ship crash into a mountain, and then when the ThunderCats come to rescue the EI in the Feliner, Two-Time uses the hologram again. Lion-O manages to fly around the mountain and lands the Feliner. Meanwhile, Two-Time flies to new Cats Lair in his spaceship, Dome-Down. He actually picks up the whole Lair and keeps it inside Dome-Down. The ThunderCats fix the Feliner, rescue the EI, and then fly to Catch Dome-Down. Once they Catch the spaceship, Lion-O uses the sword to defeat Two-Time and send him flying out of the ship. Then they return Cats Lair to its proper place.

THE TOUCH OF AMORTUS
Mumm-Ra orders Amortus, a being he banished to the Land of No Return centuries ago, to destroy Lynx-O. Amortus makes Lynx-O crash in the Thunderstrike, and then he touches Lynx-O's face. The spell from the touch makes Lynx-O feel like he is an outcast, so he leaves to join Amortus in the Land of No Return. The other TCats, Lion-O, Panthro, and Cheetara, go after him. In the Land of No Return, Amortus again touches Lynx-O, this time causing him to turn to stone. The other TCats arrive and try to beat Amortus, but he touches all of them, causing them to start turning to stone. But just as Lion-O is about to turn entirely to stone, he calls the Sword and it breaks them free. It also releases other warriors trapped by Amortus, and they all come and defeat him. Lynx-O is rescued just in time- just before the stone is permanent- and they all go home.

THE ZAXX FACTOR
Vultureman escapes from exile by hijacking a bookmobile. He finds a disk containing ancient history about two powerful evil forces on Third Earth: Mumm-Ra and his enemy Zaxx. Zaxx used a Rosencrest medallion, but Zaxx was defeated when Mumm-Ra stole the medalion trapping Zaxx in it. Vultureman plots to get the medalion, defeat Mumm-Ra, and rule the universe. So Zaxx uses Vultureman to find and defeat Mumm-Ra. But there's a terrible "side effect" to the medalion, anyone who wears it loses his own life and BECOMES Zaxx. When Vultureman learns of this, he changes his mind. The ThunderCats get caught in this situation when Vultureman attacks Panthro and Snarf and after they crash, Snarf dissappears. Zaxx then uses Snarf to attack Mumm-Ra and Zaxx takes over Snarf's body. The other ThunderCats arrive and save Snarf. Mumm-Ra defeats Zaxx once more by takin the medalion, but the pyramid also collapses on Mumm-Ra.

WELL OF DOUBT
The ThunderCats use a new Tower signal to guide a Thunderian ship in; aboard are Baron Tass and Mr. Grubber, a devious pair of Thunderians. Later Lion-O sends Torr, Baron Tass and Mr. Grubber to get water, but on the way the Baron stops at the Well of Doubt and gets some of its water. The water causes a person to become very doubtful of his own abilities. When they get back to the ThunderCats, Baron Tass gives some of the water to Lion-O. On the way to inspecting the new Tower in the Whisker, Lion-O feels the effects of the water and causes the Whisker to crash. Tass comes back (from getting his Guardsman, giant stone-men), and has them attack the ThunderCats. Jagara has the others hold the Sword, and when Lion-O grabs hold of the sword, he's free of the water's effect. Then he fights off the Guardsman, and makes a storm, which causes the Guardsman to fall apart, and Tass promises to change his ways.

THE BOOK OF OMENS
New Thundera is being torn apart and the ThunderCats must present certain artifacts at various dangerous loCations that used to be beautiful places, then Lion-O must go into the book and give the Key of Thundera to the guardian of the book "at the 24th hour," or the ThunderCats will be frozen in time and New Thundera will be destroyed. But Mumm-Ra steals the book and key and journeys into the book himself. He wants to save New Thundera BUT wants the ThunderCats frozen in time. But the Ancient Spirits of Evil try to stop Mumm-Ra because they fear if Mumm-Ra went into the book, their powers will cease to exist. The other ThunderCats run into problems also at the various loCations they are supposed to be at. Lion-O goes into the book using the Sword of Omens and battles Mumm-Ra one on one, but even when Mumm-Ra cheats, Lion-O still wins... just in time.
