The Paradox Brothers are obtainable through the event "Paradox Brothers: Guardian of the Gate!" which works similarly to the other Legendary Duelist character unlock events. The event's first appearance is May 24 -31.
Para and Dox, are brothers who duel in a tag team format that worked as eliminators. They were hired by Maximillion Pegasus in the Duelist Kingdom tournament, and ended up dueling against Yugi and his companion. It was also the first tag team duel in the anime/manga.
