Team Synopses
Subaru Whisker has returned from his previous defeat against the heroes and he begins a new scheme. Using a virus developed by Dr. Von Gerbil, he has gathered seven beastmen to follow his cause, titling them "Chimeric Lords." Witnessing this in secret, Ryuji Takamoto takes off to warn the heroes.

Team Shock
Thunder, Fluff, and Clawface notice Ryuji approaching them after what he saw. He tells the three beastmen that Whisker is back and has recruited seven beastmen to follow his beliefs. Thunder agrees that the Chimeric Lords must be stopped before Whisker launches the same virus on all of the Petro Islands, so he, Ryuji, Fluff, and Clawface begin their adventure.

Final Chapter
Team Mystery has just revealed who their client was. It was, in fact, Subaru Whisker and Dr. Von Gerbil. They revealed that they were not the ones who unleashed the virus. After telling the other heroes about this, they find the true mastermind of this scheme: Zero One. He reveals his true form by fusing with the Chimera Fleet and the defeated Chimeric Lords, transforming him into a mechanical beast.

When Zero One attempted to fuse himself with the Virus Machine, Thunder in his chimera form put a stop to him, thus saving the islands once more.
