Potara (ポタラ Potara) is the third chapter of Super Dragon Ball Heroes: Dark Demon Realm Mission!.
Chronoa discovers two changes in history and decides to split into two groups, she goes with Goku: Xeno, and Future Trunks goes with a new helper - who turns out to be Vegeta: Xeno. Vegeta: Xeno tells Trunks that he will prove he is the strongest, not Goku: Xeno. Vegeta: Xeno wants to get going immediately, but Chronoa tells him that they all must pose first, Vegeta: Xeno ignores her and tells her that they should just get going.
Vegeta: Xeno and Trunks arrive back in time to Age 767, and Vegeta: Xeno gives Trunks a device from Bulma that can locate the Dark Dragon Balls. The device leads them to the Cell Games arena, where they see the Z Fighters including Gohan already defeated by Cell: Xeno, who has a Dark Dragon Ball merged in his chest. Vegeta: Xeno easily beats down Cell: Xeno and then destroys most of his body with a Final Flash, shocking Trunks with his strength. Vegeta: Xeno prepares to finish Cell: Xeno off but is suddenly attacked by Demon God Gravy before he has the chance. While Gravy brags about his strength as a Demon God to his companion, Putine, Trunks catches his father as he is sent flying and realizing that they are outmatched by their enemies, he places the Potara he obtained from Chronoa onto himself and the unconscious Vegeta: Xeno, fusing the two into Vegeks: Xeno.
Vegeks: Xeno suddenly appears, striking Gravy and announcing his identity, Gravy attempts to attack again but he is easily knocked down, angering him. Putine states that they must take them down, as they may get in the way in the future as she uses her dark magic on Cell: Xeno, causing him to undergo a Dark Evolution.
