New Features


  • This is the only Bakugan season to feature brawlers and Bakugan hailing from every planet introduced in previous seasons: Earth, New Vestroia, Vestal, Neathia, and Gundalia.
  • Like the previous season, only Drago and the main antagonist (Razenoid) evolved.
  • This is the only season without a team of six antagonist Brawlers of each Bakugan Attribute, with Wiseman in Arc 2.
  • It is the only season that has Bakugan with different Attributes from previous variations.
  • Arc 2 is the only season where the main Battle Brawlers use two attributes (Dan: Pyrus and Haos, Shun: Ventus and Darkus, Marucho: Aquos and Subterra).
  • Arc 1 is the only season where the Battle Brawlers' main female member (Paige) did not have a crush on Dan.
  • This is the only season where the Japanese dub was not aired on TV but made available through non-Japanese online legal streaming.
  • The season's working title, according to some early material and animation sheets, was Survival Force (サバイバルフォース). Some time later, it was changed to Mechtanium Surge, presumably a portmanteau of "mecha" and "titanium."
    • The name was also seen on an image of a shirobako (internal production DVD) cover tweeted by Mechtanium Surge's character designer and chief animation director, Yoshihiro Nagamori.[2]
