Here's my top 5 (based on my experience from Online Battles):

1. Batman AK (he's built to survive against any opponent, which fits with his standard in the comic LOL)

2. Killer Frost (annoying as hell when paired with health regains on her sp1...)

3. Raven Prime (I solemnly swear that so far I have NOT loose any matches so far mostly thanks to her help)

4. Martian Manhunter Blackest Night (if use correctly, he can quickly shred the opponent's team like hell; also, most of the time I prefer to use his Supermove during his LIFEDRAIN stage, since it can heal my teams at greater amount, and also since even if the opponent's gonna block, I'll still be able to have back at least 25% maxed health for my characters)

5. Either Batgirl CC, Deathstroke AO, or Static Prime. The reason why I picked these 3 are because I can INSANELY knocks off a very high portion of the opponents health with just the right gear, combine with their own passive, and the right teammates.
