At the mountainous construction site, the workers discover a strange large robot in silhouette called Balzion the robot ally of Bio Hunter Silva. This causes the workers to flee from its appearance and it begins to make a rampage by hitting yellow lasers from both of its eye and creating landslides from within. This causes the Biomen to investigate these sudden attacks. Blue3 uses his Super Electronic Ear which he senses a terrible force is causing havoc to another place which he informs them while Green2 uses his Super Electronic Scope to detect someone's approaching and to see Silva approaches to the robot which they knew him as the Bio Hunter as they tie cover and hide. Despite their efforts, Silva easily detects their Bio Energy from within as he senses their presence while hiding as they attempt to make a stealth attack against him but failed as Silva manages to hit them with his Anti Bio Blaster and flees in a hurry. The Biomen became wondered why Silva left the battle.
At the Bio Base, Peebo becomes strange on Silva's actions and realizing that Silva was searching for Balzion. Once he merges with the Balzion, he would completely destroy the Earth much to his horror and he cannot forget of what he had done for destroying the Bio Star and it's all up to him to stop Silva as he gets his own Bio Laser and leave but is unaware that Shirou is calling him in the base. The Biomen return to their base to find Peebo until he was shown at the monitor which he attempts to stop Silva alone. He also informs them about Silva's mission to find Balzion and he will stop him for getting it and the group will use full of Bio Energy without him. After Peebo hung up to do his final mission, the Biomen decides to find him with no other choice.
When Peebo tries to find Silva, he saw a yellow lightning even other people saw this as well as it manages to destroy the satellite base. As the weaken man almost fall unconscious, he was confronted by Silva as he completely lose consciousness Silva notices it was the robot Balzion but is unaware that the weaken man was just a disguised mechaclone knowing of his location. Silva finally reunites with his robot ally, he does not realizes it was a trap set by Farrah and Mettzler until Peebo confronts him. Silva becomes confident to see Peebo fight despite he was shaking himself in horror from his appearance and Silva demonstrates how its done by attempting to shoot him directly. Due to Peebo's scare, he got caught from their trap while avoiding the blast. Peebo wonders about what's the trap come from while being bound in chains as Silva attempts to shoot him. Peebo attempts to shoot his gun scarily but manages to hit Mettzler from behind. The Balzion that Silva searched was none other than a disguised neo mechagigan, Battle Megas. Peebo now realizes that the trap set by the Neo Empire Gear is to trap Silva after noticing the mechagigan's appearance. Silva becomes angered from tricking him as he attempts to shoot Mettzler with his Bio Blaster but Farrah manages to shoot him causing him to avoid. Silva attempts to shoot both as both Farrah and Mettzler eventually teleported.

The group are soon attacked by Silva from his blaster gun and sensing their Bio Energy. Peebo now explains why the people gives them Bio Particles due to their purpose to protect their planet from any invasions will come and go and destroy the last of it. It was the destiny of the Biomen to work together and stating that they are not his enemies which Silva refuses to know and stating that the Bio Energy was his. Peebo still tells him that the Neo Empire Gear is their enemy as Silva refuses to believe and hits him with his Anti Bio Blaster as the Biomen manages to protect Peebo from being hit and Red1 states that both are going to reckon with the Biomen. The group are now fighting against Farrah and her squad while Farrah and Farrah Cat faces off Silva in a gun fight which they are equally matched.

When the Biomen attempts to follow their trail, they were blocked by Mettzler who attempts to hit them with a blast to summon mechaclones to corner them but in it's illusion type. Despite his efforts, Red1 eventually knocks Mettzler with a Bio Blaster from his eye and the group are soon defeats him with a Bio Electron Charge. The Biomen now faces Battle Megas which is now piloted by Farrah and the group activates the Bio Dragon in auto-control launch as the group enters the Bio Dragon to form their Bio Jets and to form the Bio Robo to fight the mechagigan.

Red1 soon activates the Bio missiles to knock the mecha with a blast even Farrah activates the missile to retaliate them. The Bio Robo now wields the Super Maser to make a electric flash to stun the mechs and eventually finishes off with a Bio Particle Cut causing Farrah to flee via emergency jet.
