The Saiyan Hero, a customizable protagonist from *Dragon Ball Heroes* and its promotional media, operates under the default name Beat in official materials. This young Saiyan sports spiky black hair reminiscent of Goku and dons a modified Saiyan battle armor with a cape during Galaxy Missions. As a Time Patrol recruit, they defend space-time continuity across timelines, partnering with figures such as Xeno Goku and Xeno Vegeta to resolve temporal anomalies. Though established as a descendant of Goku, their precise lineage remains unspecified. Early missions involve training under Great Saiyaman 3 and mastering the arcade game’s card-based combat system, charting their growth from an untested fighter to a warrior capable of challenging divine beings. Transformations define the Saiyan Hero’s progression, unlocking Super Saiyan tiers up to Super Saiyan Blue through combat and training. During a 10th-anniversary episode, they momentarily achieve Ultra Instinct Sign while battling Demigra, showcasing an aptitude for divine techniques. Their journey spans arcs like the Prison Planet Saga and Demon Invader Saga, intersecting with timeline-manipulating scientist Fu and adversaries such as Mechikabura and Cumber. Gameplay mechanics emphasize teamwork, allowing them to synergize abilities with allies like Frieza or Android 18 for enhanced combat versatility. In spin-offs like *Victory Mission*, the Saiyan Hero displays a penchant for phonetically spelling words mid-conversation, alongside leadership growth within the Time Patrol. These narratives balance their strategic acumen with martial prowess, maintaining consistency in their role as a player surrogate across media. Recurring visual motifs and mission-driven storytelling reinforce their identity, though details about their life beyond Time Patrol operations remain unspecified, with no elaboration on pre-recruitment history or personal relationships outside professional alliances.
