Domino

In the comics, Domino is known as the partner, confident, and lover of Cable. Her special mutant ability is that she can control luck in her favor – subconsciously, she initiates random telekinetic acts which make everything go in her favor. Of course, the objects she subconsciously manipulates need to be in her line of sight and the situation needs to be a stressful one (such as during a fight).

And this is a pretty useful skill, whose extent is not known. However, for the powers to activate themselves, she needs to take part into the fight. Furthermore, she also needs to take action. For example, if someone shoots at her and she stands still, she will be shot – but if she moves trying to avoid the bullets she will succeed. Or if a building collapses and she stands still, she will become a casually – however, if she moves and tries to avoid the falling bricks she will succeed. She manages to do that because her brain transmits bioelectrical pulses which guide all her movement – subconsciously, obviously.

Besides this useful power, she is also a skilled marksman, with all sorts of weapons, while also being an expert in explosives. When Cable is not around, she is the leader of the X-Force.

And just like Cable, Deadpool, and Wolverine she is also the result of an experiment which was considered a failure – most likely because she cannot control her power.
