In Equestria...

Caboose was knocked out, and Sigma approached him. "Time to die, you fucking pathetic waste of space!", Sigma said. Suddenly, Sarge, Simmons, Grif, and Tucker charged at Sigma, firing.

"Attack!", Sarge screamed.

"We're gonna fucking die!", Grif nervously shouted.

"Okay...", Sigma said. He slammed his hand into the ground, summoning a domed energy shield around him that blocked the explosions. He then leaped out through an opening at the top and attacked Grif (grabbing the Brute Shot in the process) and Tucker who quickly rolled out of the way. Simmons then raised his rocket launcher up and fired at Sigma.

"Take this!", Simmons shouted. Sigma nimbly flipped over the rocket and crashed down in front of Simmons, slicing his launcher in half with Grif's Brute Shot. Tucker took out his sword and swung it at Sigma, but he blocked the blow and knocked him aside. Sarge raised his shotgun and fires, but Sigma blocked that as well. In a rare act of bravery, Grif suddenly pounced onto Sigma's back and grabbed him by the neck, throwing him off-balance.

"Yah! Ah, ah, ah, this guy's like a bear!", Grif muttered as Sigma grabbed the orange-clad soldier and threw him off, but as he fell, Grif reclaimed the Brute Shot. "Yoink!" With Sigma now unarmed, Sarge charged forward to tackle him but Sigma punched him to the ground then grabbed him by the leg. Sarge fired again but the Meta dodged. He then swung him around twice and flung him into Grif and Simmons.

"Guys, this plan isn't working!", Tucker said. Suddenly, something hit Sigma. The Mane Six charged at the Artificial Intelligence, with Twilight and Rarity rapidly firing blasts of magic.

"Come here, you big son of a bitch!", Sarge said as he fired his shotgun from behind Sigma. However, Sigma grabbed the shotgun and tossed it aside. He grabbed Sarge by the neck and began to strangle him. "Hey Grif! I've lost my shotgun! What am I going to do without my shotgun? Shotgun, dammit!"

"There isn't a Warthog around here, dummy!", Grif shouted.

"Which means I win!", Sigma said. "Any last words, Sarge?!"

"Yeah, I got one", Sarge replied. "Now!" Suddenly, Tucker's sword stabbed Sigma in the chest, which then moved upwards, splitting the head in half, causing the ten A.I.s to escape Maine's body. The sword was wielded by Caboose, who regained consciousness during the fight. He opened the A.I. Storage Unit, which began absorbing the Artificial Intelligences. Sigma, however, managed to escape. He reached a human height and faced the heroes.

"You think you've won?", Sigma asked. "I am the ultimate A.I.! You can never defeat-" Suddenly, a revived Agent Maine grabbed the Storage Unit and used it to absorb the A.I. that was assigned to him. "No! You can't do this!"

"Shut up", Maine growled. "What do we do with this thing?" Suddenly, the Storage Unit began to shake. It then exploded as all ten A.I.s combined. "Okay, seriously: WHAT THE FUCK?!"

"I AM FINALLY THE PERFECT ARTIFICIAL INTELLIGENCE!", Sigma bellowed as he looked down at the heroes. He was now ten times bigger than a human.

"RUN!", Caboose screamed. "This is my fight!"

"You don't have to tell me twice!", Grif said as he and the others ran through the Blood Gulch portal.

FIGHT!

"This will be over quick!", Sigma said as he stepped on Caboose. However, the blue-clad hero used his super-strength to hold up the massive foot. He used the Great Key to slice the foot off, but it quickly regenerated. However, using his enhanced strength, Caboose shoryuken'd the massive beast in the crotch, dealing some heavy damage. "Gah!" Caboose then hurled the Great Key into the air, and it flew straight into Sigma's right eye, dealing more damage. "OW!"

"You're right, Sigma! This will be over quick!", Caboose said as he leaped high into the air and latched onto the Great Key. He dug it deeper into the wound, causing more damage... and excruciating pain. "My name is Michael J. Caboose, and I... hate... YOU!" He leaped off of the monster, sword in hand, and threw it at the left eye, completely blinding the villain. He used a wrist-mounted grappling hook to swing up to the back of the monster's head and delivered a powerful kick that caused Sigma to fall forwards... causing more excruciating pain. The sword completely broke through the eye. "It's over." He picked up the broken Storage Unit and put it back together. It absorbed the massive beast.

K.O.!

Back at Blood Gulch...

Caboose held the Storage Unit. However, Maine died because Sigma had full control over him, so that meant that Maine no longer had a soul.

"Buen trabajo, Caboose. Ahora puedo deshacerme correctamente de este dispositivo (Good job, Caboose. Now, I can properly dispose of this device.)", Lopez said. The Mane Six and Spike approached the blue-clad soldier.

"Thank you", Twilight said as she and her friends returned to Equestria.

Later...

"Bueno. La Unidad de Almacenamiento de Inteligencia Artificial y los monstruos dentro ya no existen (Okay. The Artificial Intelligence Storage Unit and the monsters within are no more.)", Lopez said.

"Good job, Lopez!", Sarge said, despite not understanding what the robot just said. "Hey, Caboose, ya did something good today. Ya saved an entire world from ultimate destruction, and you also stopped all ten A.I.s from causing said destruction. Ya might've lost a friend, but remember: We're here for you."

"Thanks, guys", Caboose said.

"Bien, en serio: tiene que haber una forma de arreglar mi configuración de idioma (Okay, seriously: There has to be a way to fix my language setting.)", Lopez complained.

"Sorry, Lopez, but unless the people who made our show say otherwise, you're stuck like this", Donut said.

"Mierda (Fuck.)", Lopez replied.

"I have a feeling that everything will be alright now that Project Freelancer is no more", Sarge said.

"¿Ey qué es eso? (Hey, what's that?)", Lopez asked. The others turned around to find a gray Pegasus pony with weird eyes.

"Guys, I don't think Twilight closed the portal yet", Caboose said. Suddenly, a purple aura appeared around the gray Pegasus and pulled her back through the portal before the portal closed. "Oh, well, nevermind."
