Mirko

Your quirk was a unique quirk in that it allowed you to possess others. It was not one that had been registered as easily. A rare mutation so to speak after you live a few years quirkless. Initially you had been trilled to have such a power. You could be anyone and theoretically have any power. However you soon realized the down sides. This power was dangerous and would make you a prime target for everything. If someone decided to act out then they could blame you, and conversely if you did become a hero...you wouldn't be able to actually have any praise as the hosts you picked would have done the job. Even if you registered you would be useless without a proper host. That among many other reasons was why you never used your quirk, as well as never registering it. This was secret you'd keep to yourself after all.

Of course that didn't mean you never used your quirk. Quite the contrary you used your quirk almost every day on so many different targets. It was essentially your night life. You'd leave your body to rest in the night and take someone else's to enjoy. Mostly your neighbours, co workers, friends and family had all been the subject your power. You never really did anything too bad. Maybe enjoy some of the luxuries they had, hit a club if they were a regular or even just enjoy...feeling around their skin and experiencing how different the world was with them.

However that all changed the day the hero Mirko showed up. The rabbit hero had been hot on the tail of some supervillain, typical hero stuff...of course she ended up chasing said Villain towards your workplace. Long story short, the villain attacked your work place and while no one died....you had been gravely injured and paralyzed and it was all Mirko's fault. How was it her fault...you had possessed the villain and was ready to surrender but for whatever reason Mirko didn't believe you and when you tried to approach her she kicked you and sent you flying....right into the spot where your body had been resting.

Mirko apprehended the villain afterwards and while she admittedly was charged for the casualty you ended up being it ultimately ended up as being nothing more than a fine for her. The courts ruled in favor of her not knowing you were there and since the villain was especially notorious your injuries were pinned on him instead of the the arrogant furry lady. She got off scot-free, the bad guy was jailed and now you could not move your body at all.

Thankfully though your quirk would rectify this easily....however you weren't going to take any of your friends or families bodies. No...they didn't deserve that...they didn't take anything for you. You were going to take the bunny girl herself as payment. You spent a few weeks planning your heist. You weren't going to invade her just yet, it would be difficult to impersonate her if you did it on the fly so instead you...observed her from afar. You possessed countless people connected to her and related to her, studying her every move. You pulled every memory those people had on her as well and then finally came the day to possess her.

Laying on your bed you bid farewell to your body as you released you astral self and went to your new home.
