Para (called Mei in the manga and Japanese version) is the older Paradox Brother. He and his twin work as a dueling team, and they show up to challenge the protagonists across both the original Yu-Gi-Oh! and Yu-Gi-Oh! GX series. Para has half of the kanji for "Labyrinth" tattooed on his head—his brother carries the other half, which is kind of their whole thing.
Pegasus brought the brothers on as Eliminators for Duelist Kingdom, where they operate as a tag team. Their signature play is "Labyrinth Wall," a card that transforms the entire field into a maze-like underground structure, turning what should be a card game into something closer to a board game with weird geometry. They patrol an underground section of the island, making them key obstacles for anyone trying to advance through the tournament.
