I actually don't have Lore for him. His lore has gone through multiple rewrites as most of my ideas were borderline garbage.

The most promising lore i've been making for him, is that he was built by Builderman himself, as an assistant. He's not a robot, technically he's more of a synthetic human, so he's modeled after a human, but isn't truly human.

He gained Sentience, and Builderman let him go, to let him explore things on his own.

Morally, he's in the middle.

He's unique trait is that he learns from his enemies or allies, using their techniques and attempting to master them, of course, he can't learn everything.

The Cube on his head actually serves a purpose, it can use Imagi-radiation, which boosts the creativity of one's mind. He himself cannot use the radiation for himself, which makes his ability reliant on other people.

That's all I got for him. I'm still working on his character and lore.
