hi! assuming I'm not pushing my luck, I'm definitely interested in this. I already have a power in mind, so I figure I'll explain it now and see if it's fair game. fair warning, it's a bit of a strange one.
the first name that comes to mind is screen manipulation: they can enter and travel through any sort of working screen, from TVs to phones to billboards, anything's fair game. in addition, if the screen is currently playing a form of visual media, they can enter into a sort of 'pocket dimension' that replicates that media exactly - in that dimension, they can bend the laws of physics to enhance their attributes to an extent (except personal durability and speed), change their form to match the media playing, and influence the 'characters' to do as they wish, to a point. they can also retrieve inanimate objects from this dimension and bring them back, with limits, such as nothing supernatural and nothing that couldn't fit through the screen.
does this sound like it would work for the RP? sorry if it got a bit long-winded!
i wouldn't be opposed to the general concept of video/screen manipulation, but i would need to see it fleshed out with strengths and weaknesses first. i'm not sure about the practicality of the pocket dimension and how it would be used in the roleplay. it's like a version of the video powers in infamous: second son though, that game was dope.
