What's that? Another Mario fanfic? This must be really bad then, just like all my other Mario fanfics and should be avoided! Well, no actually, at least I hope it won't be bad. Have any of you seen Game Theory? This fanfic is based off one of MatPat's Game Theories from YouTube. So if you haven't seen him discuss how Mario is a psychopath, how Bowser is an orphan and how Rosalina is the child of Peach and Luigi, then go and watch it, now! What's that? You've watched it many times and you're a big fan? Fantastic, then this story is perfect for you.

Mario was ten when it happened. He watched from a distance as the construction began to creak, and bits of it chipped off. Suddenly, the whole thing collapsed, sending pieces of wood crashing to the ground, crushing all beneath it.

Including Mario's father.

Feeling a hand on his shoulder, Mario looked around, to see that his little brother Luigi was hiding behind him, trembling like crazy.

"Is…it over yet?" Luigi asked his voice a little shaky.

"I…I can't tell," Mario replied. "I'm gonna go check it out."

"No!" Luigi stopped his brother in his tracks. "I mean…uh…be careful, Bro."

But before Mario could investigate, his mother appeared, telling him firmly that he shouldn't go any closer, it could be dangerous.

"But Ma, I want to see if Dad's OK!"

Before anyone could reply, all of a sudden, one of the bricks from the wreck jolted slightly. Everyone felt silent, and kept their eyes on it.

It budged a little, then a little more, but instead of the man they wanted jumping out, out leapt a huge ape, with a younger ape on his back.

Donkey Kong.

He cheered at his victory, and scampered off. Finally free from his cruel master. With the ape gone, Mario and Luigi's mother carefully approached the construction ruins. She sifted through debris, but when she finally found who she was looking for, it was too late.

Jumpman was dead.

Squish.

There goes one ant.

Squish, squish.

Two more.

"What are you doing, Bro?" Luigi asked, sitting next to his brother.

"What does it look like?"

Mario found strange pleasure in killing ants. He squished three more, one after another. However, Luigi didn't like his brother's new hobby. Every time Mario crushed an ant, Luigi flinched; Mario noticed this, so did it a couple more times.

Eventually, Luigi couldn't take it any more, and cried: "Stop it!"

Without hurting the ant, he covered it up with his hands, protecting it from Mario's wrath.

"It's just an ant, Weegie," Mario scoffed. "Why do you care?"

"It's a living creature, Bro."

"Animals don't deserve to be here. They're lower than us."

As dark as this statement sounded, Mario had been saying a lot of things like that lately, Luigi was used to it.

"You don't have to squish them!"

"Like you can stop me. Now give me that ant."

"No."

"Give it!"

Luigi held the ant out of Mario's reach, Mario jumped for it, and they ended up in a fist fight.

As they rolled onto the floor, trading blows, it wasn't exactly what you would call a fair fight. Mario was on top, punching the living daylights out of his brother, whereas, Luigi was concentrating on protecting his face, rather than fighting back – he wasn't a violent person.

This wasn't about the ant anymore; this was about trying to control one of Mario's famous rages.

Eventually, the fight had to stop when Luigi got punched on the side of the face – and he yelled.

"Ow! Bro, what'd you do that for?"

No reply.

"Am I bleeding?"

"No," Mario lied, watching blood slide down his brother's face.

Luigi glanced at him, and Mario's eyes darted straight to the floor, unable to keep eye-contact.

"Look, Bro, I know what this is about. It's about Dad, isn't it?"

"No," Mario lied again.

"It's OK. You can be honest with me."

Reaching out, Luigi placed a hand on his brother's arm. Although this was meant as a kind, reassuring gesture, Mario immediately felt restricted and claustrophobic.

He pulled away. "You're wrong! And I don't need your sympathy! I don't need you anyway, you're just my little baby brother! I don't need anyone, I'm better off by myself."

"Mario-"

"Leave me alone!"

That was the day that Luigi's brother stopped being…his brother.

He would manipulate, and punish Luigi for no given reason, only to then disregard and ignore him.

After a few days, Mario's mother had noticed something was up, so she took him to a doctor. And soon…

Mario had been diagnosed with ASPD.
