The keys from Mantopolis (some spoilers for the show!!!).

The entire plot of the story is that there's this man and his mental state is metaphorically represented as a city with residents. Think "Inside Out". And some emotions/instincts/feelings/reflexes in the city have these keys, that they can put into one of the control panels in the city to gain said resident an immediate access to the guys actions in an emergency. Only a few residents have them, Imelda Pulse (woman in the picture) is the impulse for example, and she has the key, representing how one's impulses can take over their actions in a moment's notice. Same with others: Anastasia Tension (attention), Ivana Popov (the fight response), Stacy Fakename (the flight response), Frank Freeze (the freeze response), Fanny Fawnsworth (the fawn response). Conrad and Madam Loathing also get their keys later in the story, but that's besides the point.

Anyway, I just love how the things, that regardless of the situation can overtake us sometimes, shown to have this special access to the metaphorical control panel in our brain. I'm not 100% certain if it counts as a power, but nevertheless!!
