Byron Arclight is a character appearing in the Yu-Gi-Oh! ZEXAL anime. He appears as the secondary antagonist during the World Duel Carnival arc. Byron was formerly involved with Dr. Faker's business, and has sworn to take revenge alongside his sons: III, IV and V. After III was defeated by Yuma Tsukumo, he made plans to target him as well since he possessed the "Original Number".
Though his appearance is that of a child younger than the rest of the Trom Family, he is their father. He was betrayed by Dr. Faker, who used him and Kazuma Tsukumo as sacrifices to open the door to another dimension. When he returned, his form was mutated into that of a child.
