8. Onomatopoeia
Onomatopoeia (which I’m just gonna shorten to “O†from here on out, for convenience’s sake ) is a creepy serial killer who tends to target non-powered superheroes. He seems to have a compulsion to verbally imitate the sound effects he hears around him, which is how he earned his name.
His first major target was Connor Hawke, the second Green Arrow, whom he shot. Connor was saved by his father, Oliver Queen, who scared O off. O returned to murder Connor in his hospital bed, only to have Oliver and Black Canary stop him yet again.
He participated in the Battle of Metropolis, alongside the Secret Society of Supervillains, and was even considered for Suicide Squad recruitment during the Missing Year, but he didn’t pop up in earnest until he started masquerading as new hero Baphomet and hanging out with Batman.
He eventually revealed his true identity, aaaand…We don’t know, because, holy heck, can Kevin Smith not finish a comic book to save his life. I get it, he’s busy, but still.
