Bill: My Money is on Iron Man
Bob: Hey, I'm rooting for the King of Swing! BANANA SLAMMA!
Fred: I just want to see blood... FIGHT!

Iron Man flew into the air.

Donkey Kong takes out his coconut gun, it fires in spurts, if it shoots ya, it's gonna hurt~

DK shoots a few coconuts at Iron Man.

Stark flew out of the way and fired a missile at dk.

OK I'm going to assume this is possible:

Donkey Kong jumps into the air, grabs the missile, and throws it back at Iron Man.

It's prolly not but whatever.

After DK grabbed the missile Iron Man tried to make it explode with a palm blast.

LOGIC? IN MAH ROLEPLAY? SURELY YOU JEST lololol.

The missile exploded and DK fell back to the ground. I don't know if he can survive that, but then again, if Mario is supposedly super strong if you bring all the video game logic together, and Wario and DK are stronger...

Donkey Kong throws a bunch of oranges at Iron Man.

Iron Man locked onto DK.

Donkey Kong pulls out his coconut gun and fires.

Iron Man fired a missile and machine guns at DK. All of the attacks thrown at IM hit and he stops firing his guns.
