Finally finished!!!
As the title suggested, Zer0 broke his helmet during combat and ready for the final blow.
Multiple people commented on what Zer0 should be, cyborg alien whatever... Now, I'm getting tired of all these "You got it all wrong" bitching and whining. I think Zer0 is a slightly augmented human, and I draw him as how I imagined him.
If you think he's something else, go draw your own Zer0.
My headcanon is that he is alien, but this is exciting and fun and he's also cute so go you
anywayz it's great details drawn in here
