Bowser and Iggy were both in Iggy's lab, a place that was filled with weird and random contraptions, and many chemical gases that were probably dangerous to breathe in. Bowser was pacing back and forth, seeming very anxious. "Iggy, this plan better work," he said.

"Of course it'll work, Dad," assured Iggy. "You kidnapped the princess a few hours ago. Mario has to be here by the end of the day since you didn't set up any levels. And then my plan will fall into place."

Bowser was still impatient. He thought Mario wouldn't show up, and the plan would be ruined before it even truly began. But even if the plan had more detail and was absolutely fool-proof, it was the fact that it wasn't his plan that made him truly anxious. He was afraid his trust in his son's hands—his crazy son's hands, at that.

"He better show up."

A few hours had passed. Bowser was sleeping on the floor of the lab, with drool coming from his mouth, when two hammer brothers came in, holding Mario. "Lord Bowser, Mario just came…" began one of the hammer bros. until he saw Bowser was asleep. "Lord Bowser?"

Iggy sighed. "Dad!"

"Huh? What?" Bowser woke up and sat up. He saw Mario being held by the hammer brothers. "Oh, Mario!" He jumped onto his feet. He noticed he had been drooling, and wiped it off his mouth.

"Ew," commented Mario.

"Shut up! Throw him in that tube thing over there."

"It's called a Multi-Transfusion Chamber!" whined Iggy.

"Whatever."

The hammer brothers brought Mario to the clear tube with many wires attached to it from both the ceiling and the floor. The tube opened, they threw Mario inside, and then the tube closed behind him. Mario stood up and banged on the tube. "Hey! You can't kidnap me! I have a reputation!"

"What about Super Princess Peach?" mentioned Iggy.

"Well…you used a wand that causes emotional breakdowns! That doesn't count!"

The hammer brothers left. Iggy walked over to a control panel next to the tube and began pressing buttons and pulling levers. "Releasing Gas #134!" he said as he pushed one, big command button. A green gas began to fill the tube Mario was in.

"Hey, what is this stuff?" said Mario. He pinched his nose and held his breath at an attempt to not inhale the gas.

"It's my newest invention: When you breathe in the gas, it activates neurons in your brain that signals nerves to pump the malevolence hormone through your bloodstream!"

"What?" asked Mario and Bowser in unison.

Iggy sighed. "It makes you evil."

"What? You can't make me evil! I'll hold my breath!"

"Yeah, but you have to breath eventually. And even if you hold your breath until you pass out, you'll begin breathing in your unconscious state."

Mario gulped. The entire tube was filled with green gas, so much that he couldn't even see the lab anymore. His face began to turn red and his heart began racing. Everything in his body told him to breathe. He tried to hold it in for as long as he could, but it was no use. He took one gulp of air, and then felt as though he was choking on it.

From outside of the tube, Iggy and Bowser couldn't see a single thing that was happening on the inside of the tube. All they could hear were gagging sounds. "Why is he choking?" asked Bowser.

Iggy laughed wickedly. "It's all a part of the process!" He laughed again.

Bowser stared at Iggy. "I'm starting to think your mom dropped you as a baby."

Suddenly, the gagging stopped. Iggy smiled and pressed the red command button again. The tube opened. The gas escaped the tube and Mario fell face-first onto the ground. Bowser sniffed the air. "Wha—that smells like my gym clothes after I play Mario Sports Mix!"

"Your sweat had a certain evil chemical I needed." Iggy went to a closet nearby. He took out a clothes pin and pinched his nose with it. He took a pair of pliers out of the closet, and ran to a metal box on the other side of the room. It read "QUARANTINE". Using the pliers, he took a shirt and a pair of gym shorts out of the closet with them. The clothes were emitting a similar green gas. Iggy handed them to Bowser. "That's part of the reason he was gagging…well, most of the reason."

Bowser sniffed the gym clothes and shrugged. "They smell fine to me." He grabbed his clothes.

Without either of the koopas noticing, Mario got off the floor and stood up. His skin was pale and his hat covered his eyes. The colors of his overalls had changed from red and blue to grey and black. He slowly walked over to a shelf of containers filled with chemicals. He grabbed and container and threw it at Bowser's head.

The container smashed against Bowser's head, releasing a boiling liquid. He fell to the ground and screamed. "AGH! IT BURNS!"

Iggy turned to see Mario. He smiled. "Ha! It worked! I made him evil!"

Mario grabbed another chemical and threw it at Iggy. Iggy jumped back just in time to avoid the green chemical. The container smashed, and the chemical burnt a hole in the floor in a few seconds. Someone screamed from the floor. "AGH! IGGY!"

Iggy gulped. "Maybe I made him a bit too evil." Mario turned to a wall of weapons behind Iggy. He charged for it, shoving Iggy out of the way. He quickly snatched a ray gun, a belt of grenades, and a club with spikes on it, and sprinted out of the lab. "Oh shit."

Bowser was still screaming, holding his face. "IGGY! My face is BURNING!"

Iggy's face lit up. "Oh, right!" He ran over to his dad and looked at the liquid. "Oh no! This is the worst thing that could ever happen! That's my Vaporizing Dihydrogen Monoxide!"

"What is THAT?"

"It's boiling water!"

Bowser stopped screaming. He put his hands down and sat up. He glanced at Iggy. "Boiling water?"

"I was gonna use it to make tea, but now it's all spilled!"

Bowser moaned and stood up. "Where's Mario now?"

"He's running around the castle with grenades, a club, and a ray gun."

Bowser facepalmed. "Ugh…you know what, let's find him."

"Find him? Are you suicidal?"

"Yes. But that's not the reason I'm finding him. I'm the most badass guy around! Everybody wants to be in the Koopa Klan! Since he's evil now, I'm sure I can convince him to join my Koopa Klan with my Bowser swag!"

"…"

"…What?"

"Your…what you just said?"

"Bowser swag—?"

"Don't repeat it!"

"It's my style! Bowser sw—"

"Don't say it again!"

Bowser walked triumphantly out of the lab and mumbled to himself, "I've got Bowser swag."
