BakuSolo replaces the BakuBoost packs since the original series in Bakugan: Mechtanium Surge and Bakugan Booster Single Packs. They contain one Bakugan, one Metal Gate Card, and one Ability Card. They are priced (three of them) higher than a BakuTrinity mostly because in a BakuTrinity you can't pick what Bakugan you get. They often have a picture and the name of the Bakugan that is in the pack. But the Gundalian Invaders BakuBoost packs only showed the picture, not the name.
