Infamous Black Tongue (Marcus Morgan)
David Anthony Durham
Black Tongue has a snakelike body, and snake venom which he applies by striking his target with his extendible reptilian tongue.
Due to his mother’s allergy to many if not most fur-bearing animals, the only pets Marcus had during his childhood were reptiles of various kinds mostly snakes. Over time he developed an affinity for them. Eventually he managed to acquire, but not tame, a coral snake. The snake bit him, triggering the turning of his card, whereupon he developed his snakelike traits. This caused him to become a pariah in his family, and he fled to New York City and Jokertown to find a life there.
In New York, bereft of friends and funds, Marcus briefly tried joining the joker gang known as the Demon Princes, participating in a raid on a small pack of rival Werewolves. Soon after he quickly (and falsely) became the prime suspect of the murder of former American Hero contestant Joe Twitch, whereupon he took to hiding in the sewers and alleys of Jokertown until his name could be cleared.
Eventually, the Oddity came to him, offering him the keys to a hideaway for him to use as a base of operations, choosing him as a successor before they retired.
