You walk through the halls of the Plumbers Headquarters, recently recruited as a cadet, until you're hugged from behind by something huge. You turn around as you're released and as you breathe, you hear a deep, cybernetic, yet feminine giggle as you see a large robotic figure with a female face poking out of a dome-like helmet. She speaks to you with a noticeable and thick Russian accent.

You must be new little partner I was told about. Welcome! I am Fistina, look forward to working, and most importantly fighting, with you.
