Killer Moth
Killer Moth started out as yet another anti-Batman. There were a lot of those, it seems. Moth, an unnamed goon whose name would be retconned to be Drury Walker, got himself a Mothcave, a Mothmobile, and started hiring himself out to help criminals escape Batman. He gave them all Moth-signals, which is a pretty good PR move.
He then set up a fake identity as Cameron van Cleer, which… wow. I have a friend who uses “Richard Ingognitus†as his go to fake name and even THAT is more convincing than “Cameron van Cleerâ€.
So Cameron somehow worked his way into high social circles and became buddies with Bruce Wayne. Eventually he and Batman came to blows, climaxing when he beat up Batman and learned his secret identity. Moth was then shot, which somehow gave him amnesia.
I…I don’t know.
Killer Moth screwed around for a while before selling his soul to the devil and turning into a moth monster. Then he died.
Honestly, most of my love for Killer Moth comes from A: His costume, which is amazing; B: His appearance in the excellent Batgirl: Year One; and C: His repeated – and fantastic – attempts to touch a lamp in the first Lego Batman game, and that’s fantastic.
