Bakugan Battle Brawlers: Mechtanium Surge (爆丸バトルブローラーズ メクタニウムサージ, Bakugan Batoru Burōrāzu Mekutaniumu Sāji?) is the fourth and final season of the anime series Bakugan Battle Brawlers, following after Bakugan: Gundalian Invaders. It contains a total of 46 episodes across two arcs; the first arc debuted on February 13, 2011 in Canada and March 5, 2011 in the United States. The second arc debuted September 10, 2011 and contains 20 episodes.


First Arc:

Bakugan Interspace gets messy when Dan learns his battling directly threatens Earth. Drago's exposure to Code Eve has infused him with incredible power, causing him to unwittingly release Mechtogan Zenthon, a new mysterious entity that wreaks havoc whenever Drago battles! While Dan attempts to regain control over Drago’s new powers, an insidious enemy builds an army of "Chaos Bakugan" engineered for total world domination! Will Dan be able to get a hold of Drago's power before its to late?

Second Arc:

Bakugan City is off to a peaceful start now that humans have communed with the Bakugan from New Vestroia. This comes to an abrupt end, however, when four Mechtogan who have broken free from their Bakugan start terrorizing the world. Not only that, but some creep called Wiseman has appeared with ancient Bakugan called the Nonets. It's now up to the Battle Brawlers to stop Wiseman, the Nonets, and the Mechtogan's greatest weapon: Mechtavius Destroyer!

Miscellaneous trivia

  • 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.
    • Without a team of six antagonists brawlers of each Bakugan Attribute (Team Anubias and Team Sellon members are just antihero roles to the protagonist, therefore only their leaders, Anubias and Sellon, respectively are the antagonists along with Mag Mel in Arc 1, while Wiseman is the only antagonist brawler in Arc 2).
    • Bakugan with different attributes from previous variations.
    • In Arc 2, the main Battle Brawlers used two attributes (Dan: Pyrus and Haos, Shun: Ventus and Darkus, Marucho: Aquos and Subterra).
    • In Arc 1, the Battle Brawlers' main female member (Paige) did not have a crush on Dan.
    • No gender changes occur on Bakugan debuted during this season, as well as no new Female Bakugan (applies both to Japanese and English dubs).
    • To have two script supervisors, the first arc being written by Yasunori Yamada, while the second arc being written by Atsushi Maekawa.
  • Like in the previous season, only Drago and the main antagonist (Razenoid) evolved.
  • 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. It also revealed a Japanese episode name of Back In Sync as well.[2]
