Trapper

Trapper, known in Japan as Giese Hunt (ギース・ハント, Gīsu Hanto) in Japan, is a ruthless Duel Spirit hunter hired by Viper to duel Jesse in the lab where Wheeler was trained. Himself a victim of Duel Spirit theft, Giese seeks to attain the yet-to-be-created Rainbow Dragon card, and lures Jesse into a battle by sealing the spirit of Crystal Beast Sapphire Pegasus in a capsule and even drained the energy of a Gokipon he stole.

In his duel with Jesse, he trapped some of Jesse's Crystal Beasts and threatened to rip the Jerry Beans Man that he stole from a boy that Trapper defeated. Jaden arrived and knocked the Jerry Beans Man card out of Trapper's hand. Jesse used Take Flight to free his Crystal Beasts and defeat Trapper. After his defeat, Trapper revealed that he used to be like Jesse until he lost that connection. Just then, the Duel Spirits he trapped (Gokipon, Watapon, Treeborn Frog, Key Mace, Petit Angel, and Thunder Kid) reappeared and caused him to disappear.
