|Nickname:||princess of Neathia|
Ever since The Visitor, Fabia and Shun have been training, showing each other their combat skills. Shun believes Fabia's story about her being the princess of Neathia, the Gundalians being the evil ones and they return to Bakugan Interspace to warn the Battle Brawlers about Ren. When they arrive Dan is about to engage Jesse in a brawl, but Fabia interrupts him and brawls Jesse for herself. During the battle Ren encourages the Brawlers not to choose sides and let them destroy each other, but despite this Dan and Jake cheered Fabia on to win. She loses due to Ren and Jesse cheating, and she starts to cry. When Dan sees this he starts yelling at Jesse who quickly leaves. Shun and Fabia soon after expose Ren for the enemy, and the Gundalian runs from the arena. Marucho follows upset at how Shun, Fabia and the Brawlers were treating his new best friend.
