|Ventriloquist & Scarface|
In an alternate universe, the Ventriloquist & Scarface was a former rogue of Batman.
Ventriloquist & Scarface's history was presumably the same as "their" counterparts from the Justice League's universe, until the Justice Lords decided to have a fascist-like hold on the world by appointing themselves rulers of their world. After the criminally insane in Arkham Asylum were all lobotomized by Superman, Ventriloquist & Scarface were rendered entirely harmless and now a far cry from what they once had been.
When the Justice League entered Arkham, a harmless Ventriloquist was seen with a lobotomized Scarface at the institution.
