Create a power based on the last media property you consumed and the medium.

Power related to the media whether directly or based on name, concept or idea. Can be an existing power tweaked but has to relate to the property in some way.

Next is the form or medium you consumed said thing. A video game is a touch based power. Film/tv is visual. If you ate a branded thing it can be taste. Music is sound.

An example would be you listened to an Image Dragons song. You are capable of creating auditory illusions you can control in anyone who can hear. You watched a documentary on animals; in your line of vision you can transform someone or something into an animal you can imagine. You played an MMO; upon touching someone or yourself you can assign an archetype of a fantasy class complete with various abilities and skills related to said class. Ate an item with an advertisement for an upcoming movie/game etc; you can regurgitate items that belong to the property in question that function normally however you’re only limited to the size of your throat.

Edit: Feel free to make the ability yourself or if you can’t think of anything let someone else make one.
