Changes

As [[Dan]] and the [[Battle Brawlers|Brawlers]] continue their search for the [[Bakugan Termination System]], they run into an ambush, by the [[Palace Guards]]. The Brawlers (minus Dan and [[Mira Fermin|Mira]]) are forced to separate, and wind up engaging in their own battles with the [[Vexos]]. Unbeknownst to them, the Vexos have rigged it so that it is impossible for them to lose when fighting with [[Mechanical Bakugan]] inside the Palace. In the end, the Vexos take the [[Ventus (Legacy)|Ventus]] and [[Darkus (#Legacy)|Darkus]] [[Attribute Energies]], (in the brawls between [[Shun]] and [[Baron]] against [[Mylene Farrow|Mylene]] and [[Volt Luster|Volt]], and [[Marucho]] and [[Ace]] versus [[Lync]] and [[Shadow Prove]]) leaving only the [[Pyrus (Legacy)|Pyrus]] to be collected in order for the [[BT System]] to be fully operational. As Dan and Mira stumble upon [[Hydron]], the rest of the Brawlers race around trying to find them in order to warn them about the trap set by [[Zenoheld]] and the Vexos. Finally, [[Spectra Phantom|Spectra]] presents a proposition of the [[Phantom Data]] to [[Clay Fermin|Dr. Clay]].

*Unlike the other episodes when only one [[Attribute Energy]] was taken, this is the only episode where two Attribute Energies were taken - [[Ventus (Legacy)|Ventus]] and [[Darkus (#Legacy)|Darkus]].
