10 Things You Need To Know About X-Men's Domino
9. Her Powers
Domino is a mutant with the ability to alter probability. In short, she has the ability to make certain things less or more likely to happen, essentially making her superhumanly lucky.
The more complicated answer is that, unlike someone like Scarlet Witch who can actually alter the laws of probability, Neena alters things through telekinesis. She has unconscious psychic abilities which allow her to affect things within her line of sight, such as nudging aside bullets so that they miss her or causing an opponent's weapon to malfunction.
Her powers also give her superhuman reflexes. Domino's body is basically able to instinctively plot out the best course of action e.g. knowing which way to run to dodge a falling rock. These powers only work if she's moving though, so if she just stood still, she would absolutely get smooshed by that falling rock.
While her powers can help ensure a bullet hits its target, she's also a well trained markswoman and an Olympic level gymnast, preferring to rely on her own skills and training than just her powers.
It's unknown just how powerful Domino's powers are, she's used them for everything from making sure she randomly presses the right button on a computer to manipulating storm clouds into shooting a bolt of lightning at a sentinel.
