「部位再生」 might represent natural healing capabilities similar to those of starfish and worms (or aliens and monsters based on these creatures), or be the result of superscience or paranormal powers. The modifiers below offer several options from myth and
fiction.
「部位再生」 can replace a severed head, if the possessor could survive such a wound (due to 「追加の頭」, 「負傷耐性」, etc.). This takes 2d+2 months.

■Alternatives
To heal HP, take 「HP再生」 (p. 70). Those who can replace missing body parts quickly need both 有利な特徴. The ability to repair others’ limbs is 「治療できる」 (p. 51). It’s possible to use 「特殊効果」 (p. 39) with the Advantage enhancement to give someone
else 「部位再生」 --but this is too slow to be useful unless the subject also gains (or already has) 「HP再生」.

■New Special Enhancements
Doubling:
　When you lose a body part, you can sprout two replacements, like the Hydra of myth! You must have enough unspent points to buy the relevant advantage (「追加の腕」, 「追加の頭」, etc.), and you must pay these points as soon as you lose the body part. Otherwise, you can only grow a single replacement. 「部位再生」 occurs at the usual speed. +25% if this works with only one type of body part (arms, legs, heads, etc.); +50% if it works with any missing part.

Reattachment:
　You can reattach any severed but intact body part by holding it in place for a minute.
「HP再生」 reduces this to 30 seconds if Slow, three seconds if Regular, or one second if Fast or better (but Very Fast and Extreme typically remove the need for this enhancement).+50%.

■New Special Limitations
Bane:
　You can’t regrow a body part if it’s lost to injury from a particular source or if the stump is exposed to a specific substance (e.g., fire) --your choice. Limitation value depends on the rarity of the attack: -10% if “Rare,” -30% if “Occasional,” or -50% if “Common” or “Very Common.”

Reattachment Only:
　You can only reattach body parts, as described for Reattachment, making your ability useless if the part is mangled, vaporized, eaten, etc. -50%.

■Powering Up
「部位再生」 is appropriate for biological body-alteration powers, 「治療できる」 power, and any divine, moral, or spirit power associated with healing. A shapeshifting power that includes such abilities as Morph might let the user rearrange his mass to replace missing parts. 才能 adds to all HT rolls to avoid or recover from crippling injuries.
