The other members include Wynton Styles, Lia Venegas, and Lightning the dog. Twelve years after the Great Collision, the Awesome Ones sneak into a restricted area of Pinpoint Park, in order to film a video for their ViewTube channel on the twelve-year anniversary of the Great Collision, in a crater caused by the Collision. While the group throws a surprise announcement for Dan's birthday, the second Great Collision occurs, causing the group to experience the Hide Matrix for the first time. Dan meets Drago, his new Bakugan partner.

Dan and the rest of the Awesome Ones and their newfound Bakugan spend their time filming videos for their ViewTube channel. This is comprised of Dan, Wyton, Lia, and Lightning, and their Bakugan Drago, Trox, Gorthion, and Howlkor respectively, training and experimenting with BakuCores. Through this experimentation, Dan and Drago discover the abilities possible with BakuCores. The Awesome Ones share this discovery with the viewers on their ViewTube channel.
