[@Steel Legion] Yea, the concept might look silly; I was trying to find a way to make my character less human to the extreme in a rather realistic setting so I don't feel detached in writing her savagery. A GMO, born through in-vitro fertilization from a surrogate mother with dubious loyalty, with a name she keeps changing to fit whichever locale she's in. 

No cultural value, no ancestry, not even any ethnicity she could associate herself to define who she is. The only thing she understands is that she's trained to bring destruction. Now imagine her having to struggle dealing with the more "human" side of the team.
