Hello, I am looking for a power for my character and I need help finding a good one. Jack Nightmare, a white haired hero, is my character and I cannot seem to find a suitable power for him. I've looked into Darkness Manipulation and all the other "dark-based" powers that aligns well with Nightmare.

Now this character is like my Superman: I've had this character in my head for a very long time. Really long time. So, in need of a power is the big priority for me in writing his storyline. I would appreciate some good help.
