Seeing the birds are in danger in their sanctuary, Shirou decides to let the birds to keep away from the dam due to his innate ability to communicate the animals as his group needs to return back to the Bio Robo as he left to lead the birds to safe much to their group's reluctance. Shirou communicates the bird to leave the sanctuary to the safety of all the flock of birds. Shirou manages to intercept the mechaclone one by one to proceed to get inside the dam. He also manages to ambush two mechaclones at the same time. Shirou discovers Zyuoh is causing all the mess inside the dam and he orders the mechaclones to attack him.

With nothing else to do, Shirou decides to escape making Monster orders Zyuoh to go after him. When Shirou gets cornered, Zyuoh accidentally slip on the cliff making Monster to carry him from the mecha's hand once he orders to deal with him. Without warning, The Bio Robo emerges to save Shirou much to his relief.

The Biomen are soon landed to reunite with Shirou and they confronted Zyuoh. Shiro transforms into Red1 to join the Biomen as they fight off the mechaclones single handedly.
