Marvel
Nick’s Spy-glass

197
S.H.I.E.L.D. Director Nick Fury rescued a small kitten (you) living outside S.H.I.E.L.D. HQ. Moved by the intelligence and bravery gleaming in your lone eye, he brings you inside naming you Spy-glass, intending to keep you as his beloved pet. He thinks you both have quite a bit in common, intends to teach you how to keep villains in line, help him oversee the Avengers, and educate you in spy craft.
He provides you with an eyepatch much like his own, yet hidden within from prying eyes is a microscopic SHIELD tech camera and mic to assist with any missions Nick assigns you.
Now go, my pretties... Either be a mundane feline that just so happens to be quite the gifted intellect, or hilariously turn out to be a shapeshifter/trickster/flerken/etc. Add in any random Marvel character you wish to also be there in the moment.
