Batman vs Black Panther
Pick one I guess? How do you choose, when they're really the same character in so many ways.
Superman vs Blue Marvel
It's really hard to argue against Superman when he has so many years of feats behind him, but it's also really hard to argue against Adam when he has no low showings. I put Adam against Superman, because he is closer in character to Superman than Hyperion, who appears to just be a lifeless super brick up until now. He simply has no depth to him.
G.L Hal vs Quasar
Some people think Hal would win, while others believe Quasar would win. Neither side ever seems to have a strong enough argument as to why one of these guys would win.
Wonder Woman vs Ms.Marvel
I believe that Wonder Woman would beat Carol. it wouldn't be easy, but eventually she would be the last standing
M.Manhunter vs Hyperion
This can go either way, it will depend on who launches the first successful attack.
Flash vs Spectrum
Monica imo is more powerful. I would give her the win, I mean how would he beat her if she was in her intangible light form?
Aquaman vs Namor
I used to believe that Namor would beat Aquaman, but I'm not too sure anymore. What stops Aquaman from shutting his brain down? Aquaman FTW for now.
Cyborg vs Vision
The Vision is a big jobber. Not sure if I'd give him the win over the Rhino. Vic FTW.
These teams are too evenly matched. I'd love to see how it would go down in a movie, or comic, but in a forum... I would hate to argue for either team.
Like Pym FTW said, prep would likely give the Avengers a decisive win here.
