Fan Casting Martian Manhunter/Jonn Jonzz in Captain Atom 2: Legion Of Superheroes

Appears as a statue but also as a consultant hero if you like? Advises the Legion and also fights occasionally but is more focused on rebuilding Mars still. Also explains in tandem with Cosmic Boy when Superman is killed by Luthor, people start believing his lies about Superman and alien's, except for a few who Luthor quickly disposes of. Explains that they've seen a timeline where Luthor becomes very despotic and hunts down metahumans. Also explains that his variation in that time was forced to leave Earth.
