- "Even if you fight to the death, you can't win, Kyojuro. Those impressive slashes you inflicted on me have already healed completely. But what about you? A smashed left eye, shattered ribs and damaged internal organs... all irreparable. If you were a demon, you'd heal in a blink of an eye. To a demon, those are just scratches."

Users possess a regenerative healing factor, meaning that they can rapidly heal and get restored back to their optimal and full health/state at an extremely fast rate. Unlike Healing, regeneration/healing factor is a process that happens unconsciously without the need of activation, resulting in a constant state of optimal health. Regeneration is a process that occurs in all biological entities, but a regenerative healing factor is much more efficient, seamless and powerful. So much so that users can recreate lost or damaged tissues, organs and limbs, sometimes slowing, or even stopping aging, something natural regeneration can never accomplish (or does so extremely slowly). The rate and amount of healing vary widely (see Levels of Regeneration); some can regrow missing limbs, others must put the limb back in place for rapid regeneration. The user is generally in very good physical shape, as their bodies are constantly reverting to a healthy state, granting them nigh-inexhaustible stamina and vitality.
The regeneration process also increases the speed of processes the body uses in the healing such as endorphin production to mitigate pain reducing the amount of time and severity the subject feels discomfort leading to an increased pain threshold. Other processes included are the production of adrenaline and the fight or flight response which are greatly extended by the increased recovery leading to increased physical performance as the subject gains elevated strength and energy while also able to push their bodies harder due to decreased sensation of pain.
At higher levels, a user can regenerate not just their cellular tissues, but also their DNA, undoing genetic mutations and breakdown, as well as maintaining one's youth by extending telomeres. This also gives them immunity to diseases and infections, undoing any unwanted symptoms, as well as providing a form of self-sustenance, foregoing the needs for oxygen and food intake. If advanced enough, the ability will cause the body to cease aging as the cells are regenerating and dying in equilibrium, granting immortality.

- Regenerative Transformation: Regenerate while changing one's form.
- Nerve Regeneration: (Neural Regeneration, Nervous System Regeneration) Regenerate one’s nerves (which usually are incapable of regeneration) and to return them back to their original state after harm. The user could use this ability to resist being stunned, going unconscious, going into shock from intense pain or permanently losing sensation in any part of the body.
- This ability may grant immunity to paralysis, stroke, mental disability or the like if the entire nervous system can regenerate.
- Phasing Regeneration: regenerate via Intangibility.
- Recovery Mode: Go into a mode made for recovery.
- Reforming: (Reconstitution) Pull oneself back together after being blown up.
- Regenerative Bodily Fluids: Have bodily fluids with regenerative properties.
- Replication Regeneration: Regenerate using clones.
- Regenerative Durability: Be more durable due to the healing factor.

- Symbiotic Regeneration: Regenerate using symbiotic power.
- Telekinetic Regeneration: Regenerate using psychic powers.
Levels of Regeneration
- Level I: Peak Human (Example: Taisuke Kano, Alive: Final Evolution)
- Wounds and injuries that take weeks to recover heal in days.
- Cuts, bruises, and light burns heal faster and more seamlessly than normal.
- Recovering from minor to moderate blood loss.
- Critical wounds such as lost limbs, damaged nerves, and internal organs cannot be healed.
- Cells that are fatally damaged, such as by burning, cannot be regenerated, resulting in permanent scarring.
- Level II: Enhanced (Example: Creed Diskenth, Black Cat)
- Minor to moderate wounds such as small cuts, bruises and burns usually take a few seconds to fully heal, with more severe injuries like lost limbs, internal organs and damaged nerves and cells taking minutes or hours to heal.
- Cellular senescence is drastically reduced, if not completely halted, granting decelerated aging/eternal youth.
- Regeneration can take place as long as the head/brain is damaged to no more than a certain level.
- Disease Immunity
- Users are near-completely unaffected by toxin or drugs.
- Destruction of the head is one of the few sure methods to ensure the use of this level's death.
- Level III: Supernatural (Example: Wolverine, Marvel Comics)
- Any physical injury will be healed instantly
- Cellular regeneration and rejuvenation would be so powerful, the user would be close to true immortality.
- Brain cells and nerves can be completely repaired, to the point of keeping the mind intact.
- Decapitation can be reduced in effectiveness as the user can reattach their heads and seal the cut.
- Contaminant Immunity
- Users are forever in their optimal health and physical prime.
- Tumorous cells will be healed to the point of returning to their optimal, healthy form.
- The only way to inflict long term exhaustion and injury on the user is to use attacks faster than the speed of regeneration at a repeated rate.
- Level IV: Ultimate (Example: Cell, Dragon Ball Series)
- Users may regenerate all damage on an ultimate scale, beyond logical possibility.
- Decapitation would be pointless as a user can regenerate a head, or the head can regenerate a whole new body.
- Impossible to exhaust or permanently injure, regardless of attack speed.
- Removal of soul or temporal erasure are the only methods of killing the user.
- Users are able to regenerate from a single cell/atom/particle.
- Level V: Nigh-Absolute (Example: Duke Gilzen, Vampire Hunter D)
- Users regenerate anything/everything on a near absolute level, with several limitations.
- One of the only possible methods to truly kill the immortal is to first find a method to negate regeneration.
- Level MAX: Absolute (Example: Lilith, World of Darkness)
- Users possess a regenerative healing factor at an absolute and limitless level.
- Users can instantly regenerate even if their body and soul are completely destroyed.
- Complete destruction results in complete restoration.
- Physical, mental, spiritual, temporal, and conceptual states will restore to full without fail.
- Cannot be nullified/erased/removed in any way.

- Healing Impairment can turn regeneration against its user.
- Damage inflicted by Irreversible Destruction cannot be regenerated.
- Regeneration while automatic, can be effected via conscious thought. (Focus on getting better)
- Function of power:
- Instant death may kill the user before they regenerate.
- Damage to the brain/head:
- Decapitation/destroying the head can kill low-level users. High-level users can re-attach their head or regenerate a new head/body. Head Liberation users are unaffected.
- If regeneration needs brain signals, damage may hinder the process.
- May lose skills, senses, memories, or other powers. Loss may be permanent.
- Healing may not include Pain Suppression.
- May also involve inflammation.
- If power is biological:
- Biological Manipulation.
- Excessive cell division may damage mitochondria and/or telomeres, causing premature aging and associated health problems. Mitochondria/Telomere Regeneration solves this problem.
- Healing too fast may cause DNA replication errors, resulting in mutations, cancer, or the gain/loss/alteration of powers (including this power).
- May still be vulnerable to disease.
- May overload of the immune response, causing allergy/auto-immunity.
- Power may replace the immune system. A user never develops natural immunity, and is vulnerable if de-powered.
