Super Dragon Ball Heroes S05E02 - Fierce Battle in the Super Space-Time Tournament! The Warriors in Black Invade!

With 7 minutes remaining in the first round, many battles continue raging throughout the tournament grounds. After defeating their attackers, the two Gokus begin fighting each other instead, while Yamcha manages to capture one of the three Time Fairies. This automatically qualifies the main timeline's team to move on to the next round, and they are all returned to the starting area, where they are greeted by the teams who managed to capture the two other Time Fairies: the Time Patrol team, and a team that includes Hearts and Cumber. The rest of the participating teams, however, do not return. Several mysterious warriors in black cloaks suddenly appear, and their leader explains that the losing teams have been erased from existence, along with their entire timelines. The cloaked leader explains that Aios is responsible for this, and instructs the remaining teams to prepare for the second round. However, Xeno Trunks is enraged by this revelation and attacks the cloaked leader, demanding that Aios return the Scroll of Eternity to the Time Patrol. Xeno Trunks begins fighting the cloaked leader, while Goku and Piccolo notice that the cloaked leader seems strangely familiar. Xeno Trunks and the cloaked leader each fire a powerful ki blast at each other, but Aios suddenly appears and negates both attacks. Xeno Trunks explains that Aios is a former Supreme Kai of Time, and Aios introduces herself as "the Selector of Space-Time."
