The robots under Dr. Psychobos' control destroyed the platform Diamondhead made. However, Ben, Rook, Thrasher, and Blastus did not fall down to the horde.
Rook was holding onto the back of the combined form of Ben as Upgrade, Thrasher, and Blastus flying in the air. Like in all cases where Upgrade combines with technology the form was black and covered with green circuits. In the center of the chest was the Omnitrix symbol/Upgrade's eye. The form had the same height as Thrasher, but there were several differences. The feet were Thrasher's but had green fire coming out of them. The legs were longer versions of Blastus'. The torso was larger, filling up the upper part of Thrasher's chest. The elbow pads were that of Thrasher's but the spikes were larger, and were Blastus'. The arms were longer versions of Blastus' and ended with Thrasher's hands. The head was shaped like Thrasher's but rounder. Not only did the head have the spikes of both Thrasher and Blastus, but their ear pads were combined as well. The most noticeable trait was the right eye being blue and the left eye being yellow.
"What happened?" Thrasher asked in amazement.
"I never felt so incredible in my life!" Blastus said with glee.
"I turned into Upgrade," said Ben. "He can fuse with technology and improve it. Right now, other than Rook, we are combined."
"That explains why my mouth moved when I wasn't talking," said Thrasher.
"I can't wait to see how my weapons work as actual weapons!" said Blastus.
"While I am happy for your joy we have bigger problems to worry about," said Rook.
The robots on the ground were forming a pile to get to the four.
"I'll handle this," said Thrasher. "Steam Nostrils!"
Two vents opened up where a nose would be and a large blast of steam blew the robots away.
"Time to get Dr. Psychobos!" said Ben.
"Defend me my robots!" said Dr. Psychobos as he opened his head.
A group of floating robots flew up, forming a barrier in front of Dr. Psychobos.
"Pain Ball!" said Blastus. A tube with plasma balls appeared on the left side of the head, and a bazooka appeared on left right shoulder.
"Agony Arrows!" said Thrasher. A large arrow launcher with gigantic arrows appeared out of the right shoulder.
"Fire!" said Ben.
The plasma balls and arrows fired at the robots in the air, causing them to fall down to the ground.
"You fools!" Dr. Psychobos. "Any one with intelligence, and in this case I use the term loosely for you four, would know that by interfering with my control would unleash a horde of insane robots on us!"
"Instead how about some of this," said Ben. "Weapon of Rage!"
A green beam swiftly came out of Ben's eye and into Dr. Psychobos'.
"My eyes!" Dr. Psychobos said when he was temporarily blinded. Since he had pincers he couldn't easily rub his eyes.
Ben/Thrasher/Blastus flew forward and Rook leapt off their back and landed on Dr. Psychobos' head, and back to Ben's/Thrasher's/Blastus' back.
With Dr. Psychobos hit in the head he became dizzy and was about to fall off his platform. Fortunately, he was grabbed before he could while the platform shattered to bits on the ground. The robots under Dr. Psychobos' control fell down unconscious as well.
Ben/Thrasher/Blastus landed on the ground. Rook got off and Dr. Psychobos was put on the ground. Ben separated from Thrasher and Blastus, restoring them to their divided forms. A flash of green light appeared and Ben was restored to his human form.
"Good job landing on Dr. Psychobos' head there Rook," said Ben.
"For a while I did not think I would participate in the final part of the battle," Rook replied.
The robots who were unconscious started to get up.
"I told you fools this would happen," Dr. Psychobos said angrily.
"Oh man! He's right," Blastus said in a panicked tone. "Me and Thrasher are still fugitives!"
"I got a plan," said Thrasher. "Ben, Rook, Dr. Psychobos you have to pretend to be dead."
"Got it," said Ben. "I trust you guys."
"It is best we pretend to be deceased right now," said Rook.
"It appears I have no choice," Dr. Psychobos said wearyingly. "And I use the term loosely.
Ben, Rook, and Dr. Psychobos laid themselves on the ground sprawled, and closed their eyes.
"We did it Blastus," Thrasher said loudly. "We not only saved Insanus from being brainwashed but we killed the organics as well."
"Yeah," said Blastus when he realized what was happening. "Those organics didn't see it coming."
By then all the robots were awake and were confused about what they just heard.
A heavily armored robot with a cape and medals came up and said, "As implied when I declare planets New Insanus I am the ruler of Insanus. Arn't you two Thrasher and Blastus the ones who befriended organics?"
"Not true," said Thrasher. "You see Blastus and I discovered that an organic mad scientist attempted to control our people through viruses in the enhancement drives. When the two organics here on the ground came we only pretended to help them. Once we found the scientist Blastus and I killed the organics."
"After that we fought through all of you guys when you were brainwashed and kill that scientist!" said Blastus.
"The organics don't appear injured," the leader of Insanus said suspiciously.
"You see," Blastus said in a worried tone.
"You know how different alien races have different biologies," said Thrasher. "In this case while they do not have any external injuries they have a lot of internal injuries."
"Good point," said the leader of Insanus. "With my authority I know give you both pardons and declare today Thrasher and Blastus day."
The robots of Insanus cheered for Thrasher and Blastus.
"You did you old man proud," Thrasher's dad said to Thrasher.
"Look Mecha-Jodie," said Thrasher's mom. "Your brother is a hero."
Mecha-Jodie belched fire.
"Doesn't this remind you of when we killed organics?" Dreadnot asked Thunderbite nostalgically.
"Those were good times," said Thunderbite.
"It's good to know you guys aren't traitors after all," Weenus said to Thrasher and Blastus. "I GUESS I'M NOT GOING TO KILL YOU AFTER ALL."
"Tacklebot guesses you guys aren't as weak as Tacklebot thought," said Tacklebot.
"And I guess you guys aren't total losers after all," said Megawat.
"I'm sorry for doubting you Thrasher," said Maimy. "We should study some time."
"Thanks everyone," said Blastus. "I know were awesome."
"Now if you excuse us were going to throw these corpses into a lava river," said Thrasher.
Thrasher and Blastus activated motorcycle modes. Thrasher put Ben and Rook on the back of his seat and Blastus put Dr. Psychobos on the back of his.
Thrasher and Blastus drove off while the robots cheered, "Thrasher! Blastus! Thrasher! Blastus!"
