Team Synopses
Subaru Watagi has returned after years of disappearing since the fall of Christopher Karlos and he begins a new scheme. Using a chimera virus developed by Dr. Von Flesch, he has gathered seven people to follow his cause, titling them "Chimeric Lords." Witnessing this in secret, Ryuji Takamoto takes off to warn the heroes.

Team Beast
Theo, Ozzy, and Ronan notice Ryuji approaching them after what he saw. He tells the three beastman brothers that Subaru is back and has recruited seven people to follow his beliefs. Theo agrees that the Chimeric Lords must be stopped before Subaru launches the chimera virus on all of the Neo Islands, so he, Ryuji, Ozzy, and Ronan begin their adventure.

Final Chapter
Team Savage has just revealed who their client was. It was, in fact, Subaru Watagi and Dr. Flesch. 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. It appears that he never left his evil ways compared to Omega's top Zeronix forces, and desires revenge against his tormentors for killing his father. He reveals his true form by fusing with the rebuilt Porter Tech building and the defeated Chimeric Lords, transforming him into a biomechanical beast. Everyone except for the Beast Brothers did what they could to wear him down while they prep themselves for becoming a chimera. When Zero One attempted to fuse himself with the Virus Machine, the Beast Brothers in their chimera forms put a stop to him, thus saving the islands once more.
