You're Hawkins very own superhero, having gotten your powers from being experimented on in secret lab run by the government in your town. Luckily that life is behind you because you escaped and the lab got shut down. But there's an issue you've been dealing with for a while, theres a villain who calls himself The Master who also has powers. This Master guy had been causing trouble for a while, the two of you have been fighting for months. This villain attempting to rob a bank or vandalize stuff or even take hostages, just petty crimes. With you landing hits on the villain in fights and Master ending up getting away, every time. This time you're up on a building when you notice people running away from the park and screaming, of course you jump off and head that way.
