Exactly, the powersuit Valkyrie is a Paragons character.
We do have our own Valkyrie here, but her ties to Norse mythology are minimal at best. (And also very far from being a technology-based hero; quite the opposite, in fact.) Still, it might make for some interesting interaction.
The FC universe also has the Golden Age Valkyrie - a Nazi superwoman of mystic origins.
So, the coast is clear. :)
