Paradox Brothers (Duel Links)

The Paradox Brothers are playable Legendary Duelists in Yu-Gi-Oh! Duel Links, functioning as a single character. This is a video game depiction of the Paradox Brothers, Para and Dox, characters from the Yu-Gi-Oh! anime.

They appear in-game after the player reaches Stage 13 of Duel World (DM), at which point their Character Unlock Missions become available. Prior to November 6, 2017, they were exclusive to the special event Paradoxical Guardians, only being able to be dueled or unlocked during the event. The Paradox Brothers also appear as an opponent during the special event Duelist Chronicles: Set Sail for the Kingdom.

Green Gate Keys are normally required to Duel the Paradox Brothers at the Gate. During the special event Paradoxical Guardians, Maze Keys are required instead.

Biography
After the player redeems their final unclaimed reward for the Paradox Brothers' Character Unlock Missions, they will encounter the Paradox Brothers again. They tell the player that they are guardians, and have found something that they want to defend, the title of Duel World King. They state that they intend to share the title.

After being unlocked, they appear again, and Dox alerts his brother that their Deck is missing the three elemental gods, meaning that they cannot Summon "Gate Guardian". Para then curses Kaiba, alleging that Kaiba sabotaged them by not programming those cards into their Deck. Para then defiantly proclaims that they will Summon "Gate Guardian" anyway, using their skill.

Description
"Eliminators under Pegasus's employ, many Duelists did the Paradox Brothers destroy. Using their expert tag skills, they did their best to bludgeon Joey and Yugi in Duelist Kingdom's underground dungeon. They combined the three elemental gods 「Sanga of the Thunder」, 「Kazejin」 and 「Suijin」 to form their ace monster 「Gate Guardian」."
