2016 The Martian ManHunter-Fanmade Trailer by Mandy G

This one owes an enormous debt to the 2010 “Martian Manhunter - Theatrical Trailer” by SouperboyX, but (mostly-- whoops!) switches out Phil Morris for David Harewood. J'Onn's big reveal on the first season of Supergirl really lit a fire under people four years ago. I wonder why nobody has gone back to this well in the years since? I didn't quite finish Supergirl season 2, but I know there's been a lot more Alien Atlas lore mined since then that could serve as extensive trailer fodder. Is everyone just holding their breath for Harry Lennix in 2021? Funny, you could describe the entire Snyder Cut saga as "General Swanwick."
