Neena Thurman (Domino)Edit
Domino is a mutant with the ability to subliminally and psionically initiate random kinetic phenomena that affect probability in her favor by making improbable (but not impossible) things to occur within her line of sight, thus causing her to have "good luck" and her opponents to have "bad luck." This phenomenon can be anything from an enemy's equipment failure to hitting just the right switch with a stray shot to shut down and overloading nuclear reactor. The full extent of her powers is still unknown.
This unconsciously controlled talent is triggered when she is in a stressful situation. This effect constantly emanates from her body at all times and is completely subconscious. However, it is also largely participatory - in order for the luck to take effect, Domino herself must engage in an action whose chance she can affect. She cannot consciously control her ability. Domino can only activate it by putting herself in a position in which she could be harmed. She has shown some level of control over her powers when she caused a lightning bolt to hit two Sentinels.
For example, if debris falling from the sky was about to hit her in the head, she would still be hurt if she stood still. However, if she tried to avoid them, she would move perfectly to avoid each and every piece about to hit her. In addition, if Domino were to stand before a hail of bullets she would be a bullet-ridden corpse. Instead, she might take action; in attempting to avoid the gunfire, she will miraculously bob and weave just right to avoid every single shot.
As a byproduct of her probability abilities, Domino's cerebral cortex emits a current of bio-electric pulses down her spine to instinctively guide her movements during such situations, which has the added affect of augmenting her natural reflexes and agility to near-superhuman levels.
