Maria aiming at Fury and Mockingbird

Queen Veranke posing as Mockingbird uses a battle staff.

The Staff is Mockingbird's powerful steel weapon used in melee combat. It can extend his height and size to make it more deadlier but non-lethal.

With the staff and her fighting athletic skills, she's a fierce fighter to be reckoned with on the battlefield.
