Game and Manga Differences

  • Besides the appearance of the main characters, and the transformation of Super Mira due to being enraged that Xeno Bardock is broken out of his control, the stories are almost completely different, the manga version taking place at the time Future Trunks was first recruited as a Time Patroller while the game's storyline is taking place long after.
    • How Future Trunks was recruited as a Time Patroller is shown in the manga chapter, a part of the story never shown in any of the "Xeno" games.
  • The Baby Hatchiyack Saga is only connected to the Dark Demon Realm Saga as a whole in its trailer, as neither Towa or the Time Patrol appear in the saga during the game.
