Taranee I'll allow (actually 1531, not 1581; 8s and 3s look pretty similar over certain backgrounds. The resdt are correct; list updated.

The primary means by which I tried to make it easier to tell the two Zoraks apart is that the Coast to Coast version sometimes sits at a table with Space Ghost and Moltar. You can see a bit of that table in that image. I tried not to use any image from the Brak Show because there are no superheroes or even characters pretending to be superheroes in that show. Thus characters are not villains or supporting cast of heroes in the context of that series, even though they are supporting characters (and borderline still villains) in Coast to Coast. Killface in Frisky Dingo is arguably the main character but in that instance there is a superhero opponent in the show.

Decades before Thunderbolts, Yogi's Space Race had super-villains pretending to be superheroes. Captain Good and Clean Kat were Phantom Phink and Sinister Sludge, respectively. They posed as heroes at the start and end of the race but acting as their true selves in the middle in order to cheat. No one ever noticed that the heroes were absent in the middle part of the race or that the villains were never poresent at the start or end of the race.
