i don't get why aquaman's trait is getting so much attention, i finish my combos regardless of the trait (tho i play low combo chars).
in no particular order
1. Deathstroke - free hits if youre not a complete idiot
2. Sinestro - basically eliminates recovery time on missed attacks, surprising offense
3. Grundy - the basis of his combos, the ultimate mind game
4. Bane - creates the oki game for him, super armor for days
5. Batman - brick wall
also lex & dd for obvious reasons. nightwing too. it's a different match when you switch over
