I’m somewhat of a Domino fan when it comes to interesting powers. I find the whole “luck power” concept intriguing. However, I’m no comic expert by a long shot and one thing kind of baffles me when it comes to her.
From what I understand, in order for her power to kick in, she needs to be actively trying to accomplish something. Example, she can dodge all manner of gun fire, if she tries. If she just stands there, she’ll get hit. So what about the idea of an enemies gun jamming or some inexplicable freak accident happens to the enemy and Domino is unharmed. How does that work? She didn’t actively play a part in the gun jamming. She didn’t make the lights go out all of the sudden. etc.
It’s where “mutant powers” slide over into pure magic.
The Black Cat also has “luck power” and it’s simply not supportable by any real science or even traditional comic book superscience. The Scarlet Witch, ditto. She actually thought it was magic for a while, until she learned it was a mutant power.
You might try to argue that these powers select favorable outcomes in a “many worlds” viewpoint of branching time-lines. If it’s possible that the other guy’s gun jams – then we’ll just make sure our consciousness falls into the time-line where it does. We perceive the gun jamming, we’re happy. Successful use of a superpower.
Luck is where one changes the future to a favorable possible outcome. That indicates that the character has the ability see and decide the future. OR, at least that some sub-unit of her consciousness is able to detect and react to the future.
So one could visualize what’s happening as something like a reflex action. Somewhere in the depths of her conscience, maybe she feels the pain of being shot, before actually being shot, and as a reflex her subconscious scans through alternate futures to find one that relieves that pain.
But like normal reflexes, they only occur without our conscience control in a limited subset of cases. Like, I can’t pour a glass of milk as a reflexive result of the desire for milk. But I can reflexively punch someone in the face as a result of feeling pain. So for “luck” based on higher order desires and aims, she has to think about it. But “luck” that protects her from pain and harm works by itself, without need of explicit concentration.
So to disable her reflexive luck, you’d need to somehow suppress her reflexes or numb her ability to feel future misfortune.
Although in the “Many Worlds” hypothesis, a person’s consciousness doesn’t follow a single timeline, it branches into all timelines too. So it’s the *story *that follows the timeline in which the gun jams.
Now there’s a concept: she doesn’t really have a superpower, but the writer has just chosen to tell about a timeline in which everything happens in her favor – at least, up to now.
