>>1565412Absolute Martian Manhunter The start makes ambiguous if the MC is sharing a body with a psychic alien ghost, or if he's just going insane, maybe both. It's a total rebooted universe and has not had any crossovers, so you don't need to worry about reading order or having any prior knowledge. Just start at #1 and read. Also, really cool art.
