Doomsday:
-I'm a sucker for the big, slow, high damage character, and the other two didn't fit my style as much.
-He also reminds me of Balrog(Venom is like dashing straight, and upward venom is like Buffalo headbutt kind of, fast d1 and d3 sweep, good air to air attacks, high damage and range, armored EX moves).
Cyborg:
-BOOYAH!
-Though i'm not a fan of the TT comics, I loved the show and Cyborg in it, and really all of Cyborgs DCAU appearances. I want to start reading some non-TT comics with him in it. too
-On a gameplay level, I like spacing and space controlling, and Cyborg's good at it, he's a beast at all ranges but he's a tad hard to use at first. I also like all of his moves.
-They made him really bad ass in this game as well, his quotes, his movement/animations, his design, his opening(he teleports in from a crumbling city like it's nothing and with a smile on his face), his winning animation, errthang.
Black Adam:
-I just fucking love the character, and they did him perfectly in this game.
Luthor:
-I like his character as well, and I like the idea of a power zoner, someone who can zone well and is big, slow, and damaging up close.
