Read the OP, and Gold Seiya is an overkill
Our friend's attempts to shut down any means of offing Wolverine have apparently overlooked soul-sucking abilities. Low-ranking Hollows from Bleach could fuck up James and bypass his adamantium skeleton through eating up his soul. Also since video game characters aren't banned apparently, Shang Tsung, Shao Khan, Raziel and Kain (the former two from Mortal Kombat, the latter two from the Legacy of Kain series) could soul suck him as well.
@Haofan123: Couldnt Hohenheim and Father ignore the compositions of adamantium with Philosophers stone? amd just transmute him or his soul?
Gluttony for sure FTW lol
I think the philosiphers stone only allows the user to preform more powerful alchemic reactions and bypass equivalent exchange, not ignore the laws of science completely. For example, an alchemist would be able to create a 50 foot wall of stone instead of a 10 foot wall, but they wouldnt be able to turn the stone into titanium. If they dont know the composition of adamantium i think they would still be unable to transmute his skeleton
@Fehafare: Which if that's the case, make this an impossible battle to figure out who could win a battle. With the ridiculous restrictions laid out, no one within anime would be capable of getting around Wolverine's adamantium skeleton and regeneration in a fight with physical attacks.
