- Resembled stone statues of winged, humanoid angels
- Baby Angels resembled cherubs, naked, infant-sized versions
- Quantum-locked lifeforms
- Could move their victims back through time with a touch,
- Consume the energy from the lives the victims would have led
- Can only move when not observed, covered their own eyes
- If they saw each other, they would be trapped forever
- One of the oldest species in the universe, evolved at the Dawn of Time
- Had to cover their eyes when in their stone form;
- If they saw each other, they would be trapped forever
