A male human?

Though she showed no interest in conversing with a humans, Mjolnir was actually really curious about the species.

She never actually met one of them before, with the only thing she knows about them being their resemblance to her kind and that they're made out of meat.

When one of the Valkyries informed her that their leader wants to meet her she got excited for a moment. Thinking that it might be her only chance to see a real, living and breathing, flesh and blood human she agreed to their proposal, after playing hard to get of course. 

Most of the Valkyries objected to the idea to the very end but they still let her inside. After a lengthy cleaning process to remove the radiations stuck to her she was led to a large building and made to wait inside what could only be the commander's office.
