They need to buff Lobo. I say that because he's the only DLC character so far that really hasn't had a chance to shine. Martian Manhunter can do almost whatever he wants to. His only real drawback is that he's pretty meter intensive if you want damage, and he doesn't have a conventional projectile. Other than that, go nuts. His trait boosts his damage by around 10%, and just about triples the range on most of his normals, plus it doesn't have any activation animation whatsoever. Basically an offensive version of Aquaman's trait. He's got some good resets too. Have fun.
