Has Cage's strength increased? He used to only be able to lift 2 tons or so. If he's up to 25ish tons, he stands a slight chance. Otherwise, Doc Octopus gets this all the way. Durable or not, Cage would get hit often and hard and I don't see him at 2 tons having the strength to do much about Doc Oc's arms.
2 ton Cage loses 9/10 (he might get in a lucky punch and take out Doc, but its highly unlikely).
Don't know enough about 25 ton Cage to make a judgment. If this is true, has his durability gone up as well?
