Emperor Vexios is dead. His evil empire is destroyed. But a new evil has risen and taken away the powers of Earth's greatest guardians: the Go Go B-Champions. To counteract this, Clarence Wong has created new Excellion Shifters that give the former B-Champions the powers of the animals. Now Aidan is the Tiger B-Champion, Elijah is the Serpent B-Champion, Dylan is the Leopard B-Champion, and Alexis is the Crane B-Champion.
