Omega Red vs Wild Child

Omega Red vs Wolverine

Arcady's last battle was quick and painless...
Clan Yashida pretty much stomps, with X-Men being second.

My vote goes for Clan Yashida!

Can anyone here even hurt Kitty?

Omega Red pheromones will work on her just fine. She has been put down by poisons and such while phasing before.
Putting that aside, there was Death Wolverine vs. Shadowcat fight where - you know, go see for youself. She can't be fully intaglible and attack in the same time. Also, Deadpool packs sonics.
