Adam Park was born on December 12, 1978 in Dallas, Texas. Shortly after moving from Stone Canyon to Angel Grove, he was selected to take Zack Taylor's place as the Black Mighty Morphin Power Ranger when he left to attend the World Peace Conference as an ambassador in Switzerland. As the Black Ranger, he gained control of the Lion Thunderzord.

When Rito Revolto joined Zedd and Rita and destroyed the Thunderzords, Adam gained new Ninja powers of the Frog, becoming the Black Ninja Ranger. He also gained the ability to pilot the Black Frog Ninjazord and later the Black Shogunzord. He was also later granted the power of the Metallic Armor. Later when the Ninja power coins were destroyed, he was given the power of the Zeo crystal, became Zeo Ranger IV: Green and gained the Zeo Zord IV.

When the evil Space Pirate Divatox threatens to raise a powerful monster named Maligore to marry her, Adam, along with the other Rangers, accepted new Turbo powers. He becames the Green Turbo Ranger, and gains the Desert Thunder Turbozord. After graduating from Angel Grove High School, Zordon chose to release Adam from his duties, that they might find other opportunities for themselves in the world. Adam chose Carlos Vallerte to take his place as the Green Turbo Ranger.

Despite his retirement, Adam continued to support future teams of Power Rangers. A year later, he helped Carlos recover his will to fight as the Black Space Ranger against Lizwizard, while temporary gaining access to his Black Ranger powers. Years later his powers would be completely restored by the Sentinel Knight. Adam was recruited by Sentinel Knight, as leader of the Retro Rangers, in their fight against Thrax and his Evil Alliance.

More than a decade after the Thrax incident, Adam was an agent of Space Patrol Alpha alongside his long time teammate Aisha Campbell, wherein the two actively monitor the universe for signs of evil activity and assist those in need across the cosmos.
