Percival functions as the Guardian Bakugan to Ace Grit in *Bakugan Battle Brawlers: New Vestroia*. His humanoid dragon knight design incorporates armor-plated steel, unbreakable horns on his head and shoulders, dragon head wrist guards, a cape granting invisibility, and three mouths firing plasma bullets. He generates black tornadoes with purple sparks during combat. Mira Fermin defeated Ace and gifted him Percival, revealing Bakugan sentience and forging their bond. They joined the Resistance to free enslaved Bakugan. Percival battled Neo Dragonoid to a draw after hours of combat, establishing mutual respect. He partnered with Shun Kazami’s Ingram to win the Vexos Tournament despite teamwork struggles. During the Alpha City Dimension Controller mission, he defeated Mega Brontes despite initial disadvantage, overloading and destroying the controller to restore captive Bakugan’s physical forms. Mylene Pharaoh captured Percival and Ace in a trap. Later, Percival teamed with Neo Dragonoid against Mira Fermin and Gus Grav’s mechanical Bakugan.
