Martin Milton used to be obsessed with the role-playing game known as Mazes & Mutants, and played it for every hour of every day. All that changed the day he was feeding the birds on his roof and a mutagen canister fell from the sky right on Martin, turning him into an anthropomorphic sparrow. He now answers to the name of "Sir Malachi, the sparrow wizard", wears medieval-style hood, tunic, cape and carries a wand with an egg-shaped decoration on top. Martin doesn't have his left leg and his new peg leg is actually a branch, which still have some leaves on it.
