Challenger Green was a disguise used by Saint Dane on Quillan in the Grand X. He was known as one of the best challengers to compete in the games until his defeat to Bobby Pendragon in The Quillan Games. He would reveal himself shortly before the fall of the territory. Green killed Jen Remudi, known as Challenger Yellow, in a Tato match that took place at the time of Pendragon's arrival in Quillan. Challenger Green is strong however clumsy and he is ruthless.
