The gravity shields were a pair of weapons carried by Nuhvok-Kal that could control gravity.1, 2, 3, 4, 5, 6, 7 They could negate or increase gravity around a target.2, 3, 4, 5, 6, 7 They made Nuhvok-Kal one of the most dangerous Bohrok-Kal2, 3, 7; as soon as Nuhvok-Kal brought them into play in a fight, it was over in seconds.2, 3, 7 They could completely eliminate gravity in a large area4, 5, 6, causing opponents to float away.1, 2, 3, 8, 7 They could be used to move huge obstacles, such as rocks.3 They could also increase gravity, making opponents too heavy to stand1, 8 or making them sink into the ground.2, 3, 7 They could increase gravity by up to 1,000 times normal.4, 5, 6 The gravity shields were detachable weapons, but they needed to be connected to Nuhvok-Kal to work.9, 10, 11
Since the Bahrag created Nuhvok-Kal by mutating an ordinary Nuhvok12, 13, 14, 15, the gravity shields may have originally been earth shields. They were destroyed when Nuhvok-Kal succumbed to its own gravity power and disappeared into a miniature black hole.16, 17, 6
