The top student in LID's Xyz course. A boy that dresses almost like a joker, Dipper uses a Constellar deck, with his aces being Constellar Pleiades and Constellar Ptolemy M7. He is turned into a card by Celina during the ARC League Championship because she mistook him as a native of the Xyz Dimension. After Zarc was defeated, he was freed from being trapped inside a card.
