Fan Casting Clayface/Basil Karlo in Batman 5: Knightfall

Would maybe be seen around Arkham, Batgirl maybe helps bring him down a bit more easily using the freeze grenades as well as handheld freeze gun (yes alluding to earlier iterations of Mr Freezes gun). All this before she goes to track down Riddler hostages. Disabled the traps remotely using the Clocktowers powerful encryption (trying to find a quickish solution to bring Riddler down) to disable the city halls generators that also power the traps and allow her and her father to storm city hall to rescue the hostages.
