Battle that you want to see in a real life comic movie ?

Sentry vs Thanos

Sentry vs Herald of Galactus

Cyborg Superman vs Captain Atom

DP Tyrant vs Odin

RKT vs Surtur and Zeus

Ultron vs Thanos

Void Sentry bloodlusted vs Madness Thor with Power Gem

Alan Scott vs Darkseid

Deathstroke vs Wolverine, Superman vs Flash, Batman vs Captain America.

Deadshot vs Batman vs Deathstroke

(Last man standing)

Superman vs Thor vs Hulk

(I quit match)

Iron man vs Wolverine

Darkseid vs S.sufer

The Joker vs Scarecrow

Deathstroke vs Punisher

Colossus vs Juggernaut vs Hulk

Deadshot vs Punisher

(only using guns).

Deadpool vs Juggernaut from his original mini-series.

Spider-Man vs Sinister Six

Deadpool vs Daredevil

Batman vs Clayface

Juggernaut would obviously not be the size of four people in the movie and Clayface would also be sized down.

Gladiator vs Thor

That I might actually see:

Magneto vs Gladiator, and X-Men vs Imperial Guard

Spider-Man vs Speed Demon

Batman vs Deathstroke

Superman vs Doomsday

Lex Luther doing a Tower of Babel to get him out of the eeeevil carpet bagger view we've seen in the other movies.

That I'm not likely to ever see:

Avengers vs JLA (I really wouldn't mind this being animated.... even if it's a Lego movie.)

Spider-Man vs Wolverine (Graveyard fight)

Wolverine's 'enemy of the state' run.

Spider-Man, Tigra & Nightcrawler vs the Kraven family. (as a sort of sequel to the comic)

Not sure about possibilities:

Would like to see Alpha Flight and Winter Guard appear, including Wendigo and Omega Red. But, Marvel has already filed claim on AF, so it can't cross with X-Men, and Winter Guard is an Avengers property.

Avengers vs Thanos

Spider-Man vs Kaine

Batman vs Cyborg

Flash vs Superman
