Tooth! My main man!
Our worlds are defined not just by their star players, but by their supporting characters, too, so we should all recognize Tooth during Black History Month. As far as I know, Tooth is not only the DCU's first black Denominated Henchman, he's the first one who is a recurring character. AND he works for the Joker. You rock, Tooth.
When the Joker became the star of his own series in 1975-76, he needed a supporting cast, which included his hapless former guards at Arkham (Benny Khiss and Marvin Fargo), and his three henchman, Blue-Eyes the Dumb Italian Guy, Southpaw the Smart Blond Guy, and Tooth the Generic Black Guy. Southpaw's in the back of that picture; Blue-Eyes is off-camera, getting run over by a truck because he asked the Joker a stupid question. When you work for the Joker, you don't have to wait for your annual review to get feedback on your job performance.
We don't know a lot about Tooth, like his last name, his background, or whether he ever wears anything other than that same blue leisure suit and black turtleneck. If you ask me, he's got to be pretty darned impressive to have survived working with the Joker for at least 10 years. Tooth needs some fanfic. If he were a Star Wars character, he'd already have 8 novels, 5 action toys, 2 fan clubs, and a video game voiceover by Khary Payton.
Dan Didio! Bring back Tooth; although he's a crook, he is an unsung hero of black comic book characters!
