The Bakugan Battle League was a battling event exclusive to Toys 'R' Us, where participants battled, traded, and conversed with other Brawlers. This was different event than others, because participants received a membership card and a "story." The story had two outcomes, and the participating Brawlers voted for each outcome. Each story sheet had boxes to be stamped. Each stamp equaled one vote, and participants received one stamp for losing a brawl, two for completing the activity, and two for winning. Majority rules for each Toys 'R' Us and whatever outcome won across all of the Toys 'R' Us in the United States, depends what the next Promo Card would be in the next event.

The dates were:

  • July 24, 2010
  • August 28, 2010
  • September 18, 2010
  • October 9, 2010
  • November 13, 2010

On Day 5, Brawlers had the choice to choose to see an "All-New Dragonoid" or an "All-New Evil Bakugan", both from Bakugan: Mechtanium Surge. The new season 4 Bakugan was Titanium Dragonoid. The picture and video of Titanium Dragonoid were shown online. On the final league event day, players received a certificate of achievement for participation.
