I know it’s a comic, but I’m always bothered by ultra extreme regeneration powers where the mass seems to come from nowhere. If Wolverine is burned down to little more than a skeleton, what is giving him the raw material to create regrown muscles?
My understanding is that it originates with the head (same with Deadpool). So if you cut off his head, a new body would regenerate from it and the old body just decays normally. Which still raises the question, what if you cut off his head and then cut the head in half?..
If you split the head, perhaps the side with more mass regenerates…? No clue tbh.
Only 2 will have a titanium skeleton with claws though.
Wolverine is difficult because of his (unnatural) metal skeleton. So whatever is attached to the skeleton will regenerate. If you slice of the tip of his finger it will just die and he’ll grow a new finger, but if all that’s left is a tip of the finger clinging to the skeleton he’ll regenerate.
So that’s how he can be in so many comics at once.
