-I LIKE THE AVENGERS OKAY?!-

The Maximoff twins weren't the only Maximoff offspring, no. They have a sister, younger by several years. She actually was with them in the experiments, but they didn't know.

She was altered more so then her siblings, she has the same powers as Pietro along with a different power. The power to become an animal, not just any animal. No. Her spirit animal. A wolf. Now classified as a monster she was chained by Hydra until her siblings escaped, that's when she left.

A few years later word comes around that a giant ash grey wolf is prowling the streets near Sokovia.

And it wears the bracelet that the Maximoff sister had been given by her older siblings.
