A possible villain origin for Equestria Girls.

Disclaimer: Dragon Ball inspired this origin story as they have good villains:

* We can all agree that Equestria Girls doesn't have enough villains or good ones. This is a story about a young adult named Artcraft. He is a tan human with dark hair, hazel-green eyes, and nerdy glasses. He's about as shy as they come; even Fluttershy would be like a stalwart knight by juxtaposition. This naturally made him ideal for bullies to pick on relentlessly; he only hung around Sunset and her friends as they were the only ones who didn't try to bully him. He respected them for that reason and found them likable.

During his private time, he would converse with his imaginary friend, Buu. Being a mental construct that was created from the grief that dwelled within Artcraft, he nodded and listened intently to him; Artcraft wasn't aware that this was shaping Buu's personality to have a hatred of all humans. He was, essentially, creating the world's most dangerous villain off of his venting, and he never knew it. Artcraft only thought about the despair he felt at that time.

Everything came to a head when Artcraft tagged along with Sunset and her friends; they investigated a falling anomaly that crashed into the Earth's surface. It was a glowing pink and completely intact chocolate bar. They didn't know that it was part of Discord's shenanigans before he was reformed; an unknown time skip had occurred, and this happened before Discord's first imprisonment by Celestia and Luna. Discord had decided to create relics containing fractions of his chaotic magic in his infinite boredom and then tossed them into the multiverse. Because that's totally not going to backfire at any point, right?

Artcraft, unfortunately, had a weakness for chocolate; he detailed the bar he ate as "the greatest chocolate bar he ever had in his life." This chocolate bar had 25% of Discord's maximum power in it for centuries until it reached Earth. The transformation took hold immediately, making his imaginary friend manifest and take over as the raging Artcraft-Buu; when he absorbed the Mayor of Canterlot City to regain his body after getting blasted by Sunset's beam of friendship, the mayor sadly lost his life, but this had... unexpected side effects for Artcraft-Buu, he became a fat and jolly pink guy with an innocent mind and the insane power of Discord's magic.

Since Artcraft-Buu was turned into what he was because of chocolate, he wanted to turn others into candy, cookies, and chocolate. He made genuine friends with Buff Biceps, who is the Equestria Girls' version of Hercule Satan. After nearly losing the only friend he ever had, who was also teaching him that killing was wrong, Artcraft-Buu was, understandably, distraught since a bandit ran in there and shot Buff in his chest. After healing Buff from his mortal chest wound, he struggled to keep this evil form in check and then purged it out, so there were two Buus: the fat one and the skinny grey one. The innocent was named Artcraft-Buu, and the evil was named Majin Buu.
