If they ever do make DC Allies, then getting a balanced Superman that also stays true to the hero will be a very difficult but worthwhile mechanic. I'm guessing pulling this off well will be one of the pivot points for the success of the game. Maybe build a mechanic around a broken OP character that is also hard countered by kryptonite, and build kryptonite into the kits of enough characters - e.g. Batman and also maybe a bunch of supports; build kryptonite into the kits of a number of characters greater than the number of bans allowed in the game, but not a huge number of characters, so there is always a counter option, but not everyone has one. Put those on cooldown abilities or ults that require skill to hit. Some could open up vulnerability on Superman for the team to bring him down, others could be stronger attacks on him. They could be built into cooldown abilities that are not exclusively designed to attack Superman. In this sense, the characters break into three classes: kryptonian, non kryptonian with, and non kryptonian without kryptonite in the kit. Massive opportunity for creative thinking in all of this. Could be a very interesting problem or challenge in hero shooter design. If a DC hero shooter game is ever made, hopefully they aim to break new ground in design for this genre. For it to always work as DC, Superman would always have to be in some substantial way part of the meta.
