The Dragon Ball Heroes (ドラゴンボール ヒーローズ) are a team of teenagers who are skilled at fighting in the Dragon Ball Heroes World.
Dragon Ball Heroes
In the God Mission 3 (GDM3) trailer, Beat, Note, Wairu, Fen, and Zen are all members of the Time Patrol's Dragon Ball Heroes team lead by Xeno Trunks and Chronoa against Mira and the Masked Saiyan.
When Dr. Auto mistakenly releases Black Smoke Shenron and the evil Shadow Dragons in the world, three of the Shadow Dragons kidnap his grandchildren Nim, Nico, and Genome. To stop the Shadow Dragons and rescue the three kidnapped competitors, the Battle Navigator Tsubasa and the Battle Princess Momo-chan, with help from the Capsule Corporation Engineer Yoshito-kun, decide to reunite a team of teenagers who are skilled at the Dragon Ball Heroes arcade game: Beat, Note, Froze, Kagyu, and Kabra. After a brief training, the team enters into the Dragon Ball Heroes dimension in order to defeat the Shadow Dragons and save the three kidnapped Android avatar players.
In World Mission, the Dragon Ball Heroes team is founded in Hero Town by Xeno Trunks (as Great Saiyaman 3) as a sub-division of the Time Patrol. Beat is a novice player who just moved to Hero Town. Sensing something special about him, Xeno Trunks observes Beat's match and challenges him. Soon Cooler appears due to an anomaly caused by "the menace" and Xeno Trunks kills him. Recognizing Beat's potential as both a fighter and SDBH player, he recruits him to join the Dragon Ball Heroes team. Joined by an experienced local player named Note , Beat is given his team jacket and both Beat and Note receive their Hero Switches, a bracelet-like device designed by Xeno Trunks and Leggings of the Capsule Corporation to allow players to physically enter the game world.
The team's base is located in secret the Hero Lab hidden within the Hero Tower of Hero Town with Kang and Kong acting as security who only permit allow team members to enter. Leggings supports the team as technician while Xeno Trunks observes them from the lab. Unlike alterations to history, the anomalies they confront in-game create alterations that would be unlikely in the official history of the real world. The purpose of the Dragon Ball Heroes team is to investigate the anomalies and find "the menace" responsible in order to prevent the game world from collapsing which can allow game world enemies to appear in the real world.
The group deal with an anomaly in the same time period that allows Raditz to survive his fight with Goku and Piccolo and allows Vegeta, Raditz, and Nappa to achieve Super Saiyan 3 after Nappa and Vegeta arrive on Earth much earlier.
Over the course of World Mission, other players are recruited into the team's ranks. Eventually "the menace" is revealed to be former Galactic Patrolman and the first Time Patroller Sealas who left the organization after a disagreement with Chronoa after he witnessed the destruction caused by Kid Buu. Driven by a misguided sense of justice, Sealas sought to acquire enough power to rewrite history. After Beat and Note use the Hero Switches to be able to fight in the real world, Beat gains his own Great Saiyaman Suit and dubs himself Great Saiyaman 4. Chronoa calls in Xeno Goku and Xeno Vegeta to assist Great Saiyaman 3 and his team against Sealas and his creation Ahms.
