I'll give it to Akuma, his durability is impressive as shit. Not to mention his range game, I doubt he'll even need Oni to win this. Although clearing distance will be one tough issue. I think he can last 20 minutes then slaughters as Oni. I'm no expert on Storm though.
Honestly five years is much too much. Fantomex is lethal no doubt about it, but Batman is one of the most efficient users of prep time. I'd reccomend five months to make it more fair. Also Gotham is his domain which is a huge advantage. Not trying to tell you what to do, just giving my opinion.
The reason for that being is Wolverines skeleton is not 100% adamantium, his parts of him have to stay fully organic so he can move. Hulk just ripped him in half at the spine tearing the vertabrae that's not metal.
I'm just not impressed. All I've seen Bane accomplish in near all of those scans is his brute strength, and as I had just said. Even if he is stronger Kingpin has shown a strength that is nearly parallel to Banes and fighting skills more advanced. Not to mention he gets his cane which could be a deciding factor.
Didn't Azreal beat Bane half to death? I enjoy Bane, but Kingpin will overwhelm him using skill and agility. Even if Bane is stronger(Which I doubt) Kingpins strength is still a threat. Especially if Bane can't touch him. With or without venom, Kingpin stomps.
