Rei Light, Unfortunate Scientist

This is my character in a DnD my friend made up. It takes place in modern day, but something is happening in the world that is going to cause an apocalypse.
This is Rei Light, a self taught engineer of 6 years, studying robotics and energy weapons.

So far, my scientist has managed to mess up his robot's CPU and communicatons systems, so he has the intelligence of a child, and can only answer yes or no questions, and speaks in sentence fragments that sound like my voice. So I guess he's kinda like Emerl from Sonic Battle, if anyone's played that.
I'll keep this updated if anyone's interested.
