Dr. alexandra the doctor from another dimension

Background
Not much is known about Alexandra or her place of origin. Not even she knows! Besides her own name, Alexandra only remembers brief snipits of her past like her fathers name, his work, and the name of the "country" she came from. It is inconclusive whether her amnesia is due to the shift in dimensions, or an event prior.

Life in Universe 30
She was summoned to Universe 30 at random by a mysterious force and was then found by Dr. Artem, Dr. Egg the Hell Doctor, and Dr. Helm during a Gate experiment. Dr. Alexandra was quite taken by Artem and is his fiancée in Universe 30. He gave her a makarov pistol that stays in her inner coat pocket at all times. Currently, she‘s working on a personal project - rebuilding an old soviet PTRS anti-material rifle with a shorter barrel for ease of use - which will sport the three gopnik lines (the tripoloski) on the stock. She has christened this weapon the "Adidas fury". This is all that is known for now, but time will tell if she regains any of her past memories as she continues to live in our dimension.
