[@Mr Allen J] She grew up with two brothers, I mostly mean street fighting as in informal not officially trained fighting. Not street fighter-esque type badassery. I also intended on editing out the bit about parkour, but evidently my edits did not save. 

This is also true, but she is also part human, I also don't see people in real life lifting cars, turning into part metal, telekinetically moving things, or flying. I think it's partially fair that not everything has to abide by real life standards.
