Shiro and the group notices it was well guarded and they soon found the ranger of the sanctuary that he chases them from earlier who is saddened to see the birds' nest fall due to the mecha was knock down in the fight and it was seen mouning the dead birds who got fall onto their bird houses. Seeing the birds are in danger in their sanctuary, Shiro 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. Shiro communicates the bird to leave the sanctuary to the safety of all the flock of birds. Shiro 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. Shiro discovers Zyuoh is causing all the mess inside the dam and he orders the mechaclones to attack him.

Two mechaclones manage to knock him into the river stream but he still make it into the shore as the chase continues. Shiro ends up in the cliff but was confronted by Thunder Megas piloted by Monster and it manages to knock him to the ground with its powered laser as his injured wrist is getting worse. With nothing else to do, Shiro decides to escape making Monster orders Zyuoh to go after him. When Shiro 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 Shiro much to his relief. Blue3 activates its Bio Missile to knock them off even a single punch to ground to put the mechaclones on the ground and smashes them into pieces. The Biomen are soon landed to reunite with Shiro and they confronted Zyuoh. Shiro transforms into Red1 to join the Biomen as they fight off the mechaclones single handedly. They quickly defeated Zyuoh with Bio Electron Charge making Monster to avenge Zyuoh from his defeat. With this, the equal fight ends in an easy bout by defeating the mecha with a single Bio Particle Cut causing Monster to flee via emergency jet.
