Regeneration is the ability to almost instantly heal from physical harm and injuries. Beings that possess this ability will often regenerate moments after being harmed, with some even being able to regrow limbs.
- When the Chosen tried to vanquish a Harpy Queen with a spell, she ignited in flames until the Titan Prometheus intervened. The Queen's burns then healed in a matter of seconds.
- When an Empusa was injured in an explosion, she absorbed a psychic blast fired by Prue Halliwell to heal her wounds.
