Doom has used his brilliance to save his family and only required as payment the right to name her... Valeria is as good a name as any.

Funnier still, The family just didn't mind the name if she was alive and healthy, even though it was a ploy.

Uncle Doom. I still liked him as Infamous Iron Man.

It's a cool name.

I’m pretty sure Dr Doom named her, since doom did something, thus the F4 owed him something
