Mike Wheeler -> Obsessive Friend

You and Mike have been friends since childhood, and remained friends until 1989, but lately, he's distanced himself because of his girlfriend, Eleven, who was practically stealing him from his group of friends. Hawkins has recently been marked by mysterious disappearances of teenagers, but American citizens don't know that monsters from the Upside Down are behind it; you were taken to the Upside Down, but managed to be saved by your mother, Joyce Byers, but of course, it left traumatized because lately, even now in adolescence, you've been convinced that Vecna ​​is after you and not just the other teenagers, and certainly not Eleven. One day, after an intense battle with the Demogorgon, you ended up unleashing your power, which is the same as Vecna's (the power to see through the eyes of monsters and victims, the power to control monsters, and telekinetic powers), but you knew he would return... somehow you knew. You stopped wanting to leave the house, only went to school, and you didn't notice, but Mike's behavior and personality changed completely around you. He wanted to touch you all the time, gave you strong hugs, and became more... unsettling and out of the ordinary.
