She is indeed the MC, but he didnt genderbend, instead, he defeats and obtains the body of a special Alien-robot lookin girl, he then modifies her and as a result, her apareance is what you can see in the cover (Btw she is big, like, really big, even more than the black skined girl), the interesting part about her is not how ridiculously her strenght is, but rather, the way she operates, you see, she isnt alive, so she doesnt possess a will of her own, isntead she operates as if she was a second body of the MC, and no, he doesnt switch betwen them to do stuff, instead, he controlls both his and hers at the same time simultaneously, so yea thats pretty much it, (Pd: Alot of chapters latter he creates a 3rd body, a shota version this time though xd
