I think it might be easier to shrink down the list by removing characters we think we should eliminate from contention, if you don't mind. If you have any misgivings, let's speak our mind now.
Ant-Man (Eric O'Grady) - I think we should have an Ant-Man; but, I wouldn't want to be stuck with the coward of the two.
Doorman - He was a pain in the butt last time. I think to eleviate an problems, he should be gone.
Mr. Immortal - Again, he's immortal....but, that's about it. He's a comedic character, and the person who has him can just say, "Yeah, but he's not dead yet."
Scarlet Witch - We could have her at her original power-level, Before Bendis. But, why even deal with the hassle?
Squirrel Girl - I like her character...but, we'll be dealing with the comedic elements presented, and do you want to debate that she defeated Thanos? For ease, I say let's just get rid of the entire GLA.
Adam Warlock - We don't know his current power levels...and, it's possible he's too uber. So, for ease of the competition, again...
Blackbolt - He's got one big power that can level an entire mountain. He's too uber with that, and without it, kind of useless to me.
Red Ghost - Without his apes, why even have him?
Night Thrasher (Dwayne) - We've got one; we don't need another.
Sphinx - He's either too uber or too difficult to pin down his power level, just like last season.
Swarm - It just takes one character of a scientific mind to take down this character. You know how to kill bees, you can probably wipe the floor with Swarm.
Cerebro - I think Cerebro is too uber.
Danger - I KNOW Danger is too uber. I saw the official Marvel bio, and Danger would be my first choice if she was in this competition.
Dagger - Cloak might be useful...but, Dagger is just lame.
