Examples: Toa ( Bionicle), Wally West ( DC Comics), Hercules ( Marvel Comics).For machines and vehicles, this would be regenerating some interior damage, along with some minor critically damaged or destroyed parts. High-Low: The ability to regenerate severed fingers, toes, or ears, minor organ damage, and even potentially reattach lost limbs. Examples: Link ( The Legend of Zelda), Blade ( Marvel Comics), Yusuke Urameshi ( Yu Yu Hakusho).For machines and vehicles, this would be regenerating damage that would normally leave large dents and openings. Mid-Low: The ability to heal wounds that would normally leave large scars, such as severe burns or deep injuries. For machines and vehicles, this would just be regenerating basic exterior damage. Low: Merely an accelerated healing ability for normal wounds, allowing the character to heal wounds that would normally take days, weeks, or even months much more quickly, sometimes even in just seconds. This is due to reasons ranging from possibility of off-screen treatment to continuity errors. Instances of characters being wounded and inexplicably recovering off screen should not be taken as evidence of regeneration unless supported by further context. Higher levels allow characters to regenerate from even more severe wounds, such as being blown to pieces, reduced to a single cell, vaporization, and even complete physical destruction and beyond. It has several different levels that range in potency from what is essentially just faster natural healing to being able to regrow limbs or organs, or even a severed head. Regeneration, often referred to as a healing factor, is the ability to heal from wounds at an accelerated rate, with many characters proving capable of regenerating from wounds that would be lethal to normal humans.
