Edit: Added a smaller version which matches most d&d miniatures.
Two-Bad is a character in the popular Masters of the Universe toy line and accompanying cartoon series, He-Man and the Masters of the Universe.
Two-Bad is a two-headed Evil Warrior who is basically two different beings sharing the same body. In some ways he is like Siamese twins, although both halves of his body are very different-looking creatures who appear to be from entirely different species. His right half is a blue creature, while his left half is a purple, scaly creature with an eyebrow-like yellow band on his forehead. His two heads have the habit of continuously arguing with one another (much like the ghostly Fib-Face in Filmation's Ghostbusters).
The character's name is a play on "Too Bad".
