what can this team actually do to Tony? he doesn't have to go hand to hand with them. he can just float a mile above them and fire rockets, or use anything on his arsenal and never even be scratched.
He get pummeled in the dust.Floating and blasting rockets?Colossus in his early days as X-Men, when he wasn't as durable or strong as now he is, fallen from like 2miles from a floating fortress in the ground meanwhile battling a huge superstrong and energy blast emitter being.He wasn't even scratched from what happened.Hulk Buster armor is outdated, Colossus grab Omega Red, perform fastball special, Omega tie up Stark, and meanwhile Colossus himself perform a superjump leaping up into the sky and make Stark crushing on land, and then he and Benji beat the crap out of him.Hulkbuster was SUPPOSED to stop Hulk, but wasn't that impressive.
Iron Man has beat each one of these guys individually in just his regular armor.
Colossus & Thing are just walking brick type characters and don't pose too much of a threat to Iron Man. A sonic blast at the start of the match should knock them out.
Iron Man has taken out omega red before, so it shouldn't be a problem especially if you give him the Hulkbuster Armor.
