In Red Lantern they mention a lot about Manhunters (who incidentally destroy). Now I know the "Martian Manhunter" The shapeshifting Martian John Jones (please excuse the lack of use of sound modifying punctuation).
Are these Manhunters all martians? Or is John just one Martian who happened to be a Manhunter?
Why are they Manhunters anyway?
Is this why Atrocitus hates John so bad?
Why would Manhunters destroy sector 666,a humanless sector?
