Yugi Muto gives the "Winged Kuriboh" card to Jaden after the latter bumped into the former in a big hurry. Yugi also said that he felt that the card wanted to be with Jaden. After obtaining the card, Winged Kuriboh became Jaden's Spirit Partner and often appeared alongside Jaden, particularly to express concern. Sometimes he would appear when Jaden needed him the most, like when he was in a tough situation, or to tell him the card he will draw could help him. In episode 4, Ms. Dorothy gave Jaden "Winged Kuriboh LV10", along with "Transcendent Wings", to which he used to defeat Chazz. Winged Kuriboh will sometimes hide behind Jaden's head after being frightened by something. During season 3 Winged Kuriboh would sometimes fight with Jesse Anderson's spirit partner, Ruby Carbuncle.
