The battle between Goku and Rirudo takes place. Rirudo fires his specialty beam and turns part of the forest into metal. Goku gets disappointed that Rirudo's fighting style is still the same. Rirudo then attacks with a drill-powered tornado, calling it a "Hyper Mega Rirudo Punch", and Goku is impressed with the power.
Goku is knocked back, and he starts firing many blasts at Rirudo. All of which were blocked, but it pushes him deep into the forest.
Back at the tower, Pan forces her way back to the room Gill was in. A few steps later, the "emergency elimination system" activates. The room distorts again, and Pan is pulled away.
Back outside, Rirudo gets up. Goku tells him that even though his power increased a lot, but Goku is confident that he won’t be beaten. Rirudo is happy; he is delighted to get the Saiyan powers Dr. Myuu's been looking for. Goku understands that he impresses him, and demands that Rirudo show his true power.
Rirudo sticks his hand out and red sparks cackle around it. Then, some metal wires pop from the ground into Rirudo. Rirudo then starts to change to a completely silver metallic form, and whole ground becomes a smooth metal. Goku prepares a Kamehameha in the meantime, and as he was about to fire, pillars of metal rise from the ground hitting him. The Kamehameha is lost, and the pillars grow into metallic trees. Rirudo turns liquid and merges with the metal.
Back at the tower, Pan tries to enter again. Alarms sound, and robots surround her. Pan tells them that they don't understand how powerful she is, and the robots step back. She walks in and blows up the siren, and the robots jump her. Pan gets pissed and pulverizes all of them. The robots wind up falling off a ledge, except one, but when Pan looks at it, it got scared and voluntarily jumped.
Pan walks a few more steps and a robot approaches her from behind. She goes to attack it, but sees it was the old scrap scientist robot she saved a little while ago, and hugs (or crushes) it. Pan asks him about the system in top floor room (where Gill is). He tells her it’s an "Elimination System of Time & Space Teleportation Device", and it is the only way to reach Dr. Myuu's room.
Pan figures it's the same device that took Trunks. She asks him how to deactivate the system, and starts to charm him. The robot eventually answers, "I don't know", which Pan responds with an uppercut. The robot phases through the ceiling and appears coming out of the floor by Pan’s feet. Pan realizes why he was considered scrap.
Back outside, Goku avoids the growing metal trees, and one of them separates and turns into Rirudo. Rirudo is thinks he was underestimated and fires his beam, which hits the forest, turning it into metal. The forest then "melts" to liquid become under Rirudo's control. The liquid metal becomes a tsunami behind Goku, as Rirudo laughs evilly...
Rirudo merges with the liquid metal again, and tells Goku that he is one with Planet M2. He can control all metal on the planet, Goku is impressed, and Rirudo fires a metal blob at him, which Goku blocks by powering up. Now, Goku wants to stop playing and fight all out.
On Dr. Myuu's planet, Myuu is giving off an evil laughter. He reviews the fight between Goku and Rirudo, and is happy to finally see the "Legendary Super Saiyan". Myuu then talks to Trunks about how he can't wait to get his data. Then tells him he (Trunks) will be able to release his power after Rirudo captures the other 2 Saiyans.
Back at the tower, Pan and the old robot gets on the elevator, just as a bunch of drones rush into it with them. When they get out, none of them survived. Pan goes to confront Gill. She figures that Gill only befriended them to lure them to M2. She approaches Gill more and the alarm activates again, and starts pulling her away. The old robot goes to the control panel and pulls out a metal cylinder that deactivates the system. Pan thanks him, and blasts the wall, that her rear got stuck in (lol).
She confronts Gill again. Gill phases into a door to the next room, and Pan decides to use a Kamehameha to blast him out. Then, the door opens and Gill is with many robot guards with various arsenals. Pan starts a Kamehemeha, and Gill activates the backup elimination system. She looks and sees the old robot subdued by drones, and she is pulled outside again. The Dragon Balls and Gill's medal are sent with her, and when Pan discovers them, she wonders why.
Back at the fight, Goku tries to blast Rirudo, but being the liquid metal of the planet, he just reforms himself elsewhere. Rirudo proceeds to beat Goku up with various "metallic" attacks. In the end, Goku tells him that he's strong, and it does hurt a little. Rirudo laughs saying he would have to destroy all the metal on the planet or run forever if he wants to live. Otherwise, he should just surrender to Dr. Myuu...
