Ninja Bird Brigade [マキナ 十勇士 (Makina Juyushi or Machina Ten Braves)] is Professor Kunagiri's squadron of Ninja birds.
Bakugan are created from the theoretical bond between a Bakugan and a Brawler. When a thirteen-year-old boy named Shun Kazami kissed his Guardian Bakugan, Ventus Storm Skyress, good-bye; it resulted in the birth of the six original Ninja Birds in a distant corner of the dimension.
The birds initially knew only three things - travelling between dimensions, being funny and looking for their "biological father." They ended up in Professor Kunagiri's manor prior to Dallas' arrival.
The Original Members all resemble Angry Birds and they can fuse like the Mechtavius Destroyer. Their powers are just as destructive as they are hilarious. Only Spinzaku and Skyress can speak human language while everyone else just crows like birds. Ingram can also speak but he muted himself to look like a badass ninja.
