Trio Trifecta was a character in the bonus episode Sports Are Just Numerology. Trio was an Oricom athlete "designed specifically to prove that robots can compete in multiple sports", who played both with and against Memphis Longhand in the Orion Combine Mechanized Sports Association (which included such leagues as Safehaven, Iron Gridiron, Zero-Gravity Double-Body Angling, and Golf).
Described by Austin as "the IG-88 of mech sports". Named when they were only intended to compete in three sports; they were positioned as Memphis's counterpoint, and so also picked up golf when he did.
