Satan, the horse.

Satan is a horse owned by John Steadman. The horse is mentally disturbed and resists any attempt for a rider to stay on him for long. As this is the case, Steadman offers a bet of $1,000 U.S. dollars for anyone who can ride the horse without being thrown off.

Maze has had an opportunity to take this offer, despite his concerns about medical bills for injuries that may result from the horseback riding.

Troy and Dillon are able to correct Satan's alpha waves using signals from their wrist computron, thus being able to ride the horse, which they subsequently win and gift to Gloria Alonzo (1980: "Space Croppers").
