Unused Character (Jade Champion?)
Although this initially looks like an early version of Houston's Palomino, it is in fact Jade Champion. Jade was a character from Interstate '76 - from which Vigilante 8 was originally intended as a console spinoff. In I-76, Jade is the brother of one of the central characters, Groove Champion. In the end, this character was cut, with no characters from the PC game making it to the consoles.
