Suicide Squad: Kill the Justice League has several cosmetic items for players to customize their Task Force X however they want. The four main playable characters, Captain Boomerang, Deadshot, Harley Quinn, and King Shark each have looks that can be unlocked through the main story, Riddler challenges, as part of special editions of the game, and as purchases in the in-game store.
