Suggested by Sonic Atrocitus is a very powerful DC villain and it’s safe to say that he is well above Man Bat’s weight class. There isn’t a whole lot that Man Bat can do against such an opponent. A single energy blast from the Red Lantern ring would send Man Bat flying. Atrocitus can also fly at far greater speeds than Man Bat which is basically game over for the fighter. Atrocitus wins.
Never bring a Green Lantern foe to Gotham, for Langstrom would perish quicker than can be counted to 70.
Agreed, Man Bat’s doomed before he even gets a chance to land. The gap in power here is massive
