My hat's off to you. It's definitely a more original way of making the "evil twin." Especially since they're the same person, just one got a fairer deal than the other. (Still, having Ghost Widow in your court helps a little.)

I have several characters who are the opposite numbers of other characters, but I usually use the Praetorian Earth and portal technology to explain their existence. Lazy of me, I suppose.

Still, I like coming up with how I can start them in the same place and then totally twist their history.

Just out of curiosity, what is Midnight Call? Assault Rifle/Devices Blaster?
