Mike touched on this above but I definitely think it’s worth mentioning again. Mental powers were definitely the first thing that came to my mind when I thought of a type of power with a skewed gender distribution, far more so than I can think of for any other power. There are certainly a handful of notable and less notable exceptions, but by far powers such as telepathy, telekinesis, emotion based powers, precognition, etc. are far more common in women. Even powers such as Armor’s armor are often explained as having some kind of mental or emotional power behind them.

I did find it interesting however that they changed Negasonic’s power set for the Deadpool movie, effectively giving her Nitro’s powers and removing her psychic gifts. Of course Tim Miller has stated they chose to include her exclusively based on her name, so my guess is that was less intentional and more a result of the movie’s creative team deciding someone with that name needs an appropriately flashier power.
