Gear so far is sadly very similar, each character has a theme that all gear doesn't go too far away from (Eg: Ivy= leaves, Bane=leather with armor, Catwoman/Canary= leather and cleavage).
I was hyped to see some stuff like Knightfall or DKR stuff for Bane (Even regular stuff that shows his arms), DK Joker or Suicide squad Harley gear but seems it's not there. I'm still unlocking stuff but I've lost hope that anything that different from the default set is gear.
Maybe it's DLC gear for later down the road -___-
