Phaedrus is a Bakugan Battle Planet chinese dragon-like Bakugan that was seen on a poster at the Bakugan Sneak Peek showcasing various Ventus Bakugan. She first appears in Stratified seeking the help of The Awesome Ones in order to save her friends who are trapped in "The Maze" and later becomes the third partner Bakugan of Lightning.
A gentle and wise creature with incredible strength, Phaedrus is a perfect balance to Lightning’s other Bakugan, Howlkor. In battle, she is highly intuitive and strategic. When she’s deployed, Lightning rides into battle on her back. The two are perfectly compatible friends and share a mutual respect for one another.
The Awesome Ones meet with Benton Dusk and are introduced to Phaedrus. She asks the AO for help to rescue her friends who were captured by Strata the Hunter in a mysterious labyrinth, dubbed The Maze. She travels with Lightning alongside the other members of the AO in a mission to free her friends.
Phaedrus rescues her friends and they return to Benton Dusk, but the other members of the AO (sans Lightning) are attacked by Strata and his Krakelios and fall into a hole, becoming trapped in the maze.
