Aquaman is not useless. Let’s get that out of the way right now. Since he’s going to be fighting on land, we figure he should sport that water suit Batman hooked him up with in the past. He’s just as strong as his Justice League counterparts, plus he has control over the creatures of the sea. Let him come into battle with a battle spear, give him some cool water specials, and we’re sure Aquaman could fend for himself quite well.
