Not totally set on this guys' design. I sorta had the idea for this modular android/robot who can switch out arms/legs, maybe more, to suit needs, or desires. Not sure how to really sure how to make that design obvious.

As part of the modular design, I imagine him being able to switch out cosmetic features, such as ears, tail and hair to look more like a different species.

Unlike Mu, he can use different magic crystals to modify is own power.
