Didi

Created by a grieving wizard after a fatal accident claimed the life of his son. The wizard, Tome, hadn't originally set out to create a Majin but rather return his son Didymos to life. When that proved impossible rather than stop, Tome decided that he would instead recreate his son through magic. Using a ritual he'd found inside his master's old grimoire he made his attempt.

If Tome had taken the time to read the ritual and it's warnings in their entirety. He'd have known that the spell created only Majins, not other species. He hadn't, however, and was left surprised and defeated when Didi and not his son stood before him. Freshly conjured, Didi was void of any personality or sense of awareness. He only stared blankly at his creator as Tome berated himself for his failure.

"Tear it all down and start over."

Didi interrupted the statement as an order and began to act. Without warning he began to ransack his creator's abode, much to Tome's surprise. Before the wizard could issue the command to stop, however, Didi spotted Didymos's corpse and absorbed it. Didi collapsed to his knees shortly after, becoming overwhelmed by a sudden flood of memories and emotions that forever changed him.

After he recovered Didi spoke his first word, "Dad?" and Tome, sobbing, embraced him.

Despite absorbing Didymos, Didi didn't become a perfect recreation of the wizard's son. Something that became clear not even days after the absorption.

A majority of the child's memories were foggy and difficult to remember for Didi. Aspects of Didymos's original personality were even altered or missing entirely as well. Didi was rambunctious, impish, and enjoyed pranks and crass jokes. All things that Tome had never seen his son show any interest in.

But none of that changed anything for him. As far as the wizard was concerned, he'd gotten his son back.

The years ticked by and Didi continued developed into his own person or at least he tried to. With the passing of time Didymos's memories and emotions became clearer to him. Which made him feel lost and confused, and he soon began to act in defiance of them. Didi did whatever he felt the original Didymos wouldn't do. Practice magic, pick fights, eat tons of candy, it didn't matter what it was so long as it was something the other him wouldn't do.

Which is exactly why he ran away two days ago. He couldn't handle it anymore, he loved his father but he couldn't live in Didymos's shadow anymore. Didi wanted, no, he needed to be his own person.
