The ability to make cartoons and warp reality? Honestly, to me it would be similar to a Green Lantern's construct creation, but having them tank big guns just to make the scenario seem animated or funny for a 4th wall breaking purpose would make them too close to Mr. Mxyzptlk. Is there any other archetype you'd wanna bring to the table? 

Anybody else? Maybe somebody wants to put a spin on Raven? Or make a female Kid Flash? Perhaps Wildcat's illegitimate were-panther son? What about another legacy teen from the JSA like Cyclone or Black Lightning's daughter Lightning? Tons of possibilities...
