Changes

[[Ace]] and [[Shun Kazami|Shun]] team up in a [[Bakugan]] Battle Tournament, in order to overload the [[Alpha City|Alpha]] [[Dimension Controller]], because it draws power from Bakugan battles. After [[Marucho]] purposely disqualifies himself in the singles round, he sneaks the others in. They almost get caught by some guards, until [[Mira Fermin|Mira]] pretends to be a huge [[Vexos]] fan-girl and they manage to slip away. As they remain hidden, the Vexos show up, and Mira notices that [[Spectra]] tosses his [[Bakugan]] the same way as her lost brother [[Keith]]. Meanwhile, Ace and Shun are having trouble getting along in the Battle Tournament and are starting to lose against [[The Dark Angels]], who are Vexos wannabes. When their opponents begin taunting them, Shun and Ace put their differences aside and finally come up with a plan. They win with ease and claim their opponent's Bakugan. Afterwards, Shun and Ace prepare for their match against [[Lync]] and [[Volt]].
