Dox (called Kyuu in the Japanese version) is the younger Paradox Brother. He and his older brother are a tag-team dueling duo known for appearing in both the original Yu-Gi-Oh! and Yu-Gi-Oh! GX series. The two literally share a gimmick—each has half the kanji for "Labyrinth" tattooed on their head.
Pegasus hired them as Eliminators for his Duelist Kingdom tournament. Their signature play revolves around the "Labyrinth Wall" card, which warps the entire field into a sprawling underground maze, turning what should be a card game into something closer to a board game puzzle. They're stationed in an underground section of the island as its guardians.
