Trapper, known as Giese Hunt (ギース・ハント, Gīsu Hanto) in Japan, is a ruthless Duel Spirit hunter hired by Thelonious Viper to duel Jesse Andersen 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 named Tom who Jesse once knew. Jaden Yuki 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.


In the dub he speaks with a stereotypical cowboy-accent.


Trapper plays a Hunting Deck, themed on the distribution of Prey Counters to his opponents' monsters to capture and immobilize them on his side of the field.
