Tommy Hagan is a supporting antagonist in the first and second seasons. He is a student at Hawkins High School. Tommy is Carol Perkins's boyfriend and Steve Harrington and Nancy Wheeler's enemy and a former friend.
Tommy was a student at Hawkins High. He dated Carol Perkins, and was a friend of Steve Harrington and Nicole. According to classmate Barbara Holland, Carol and Tommy had been "having sex since, like, seventh grade".
The same group of teens - minus Barb, who had mysteriously vanished - hung out together at school in the days after the party. Nancy, however, became concerned about Barb's disappearance, and gradually became less active in the group.
When Jonathan Byers was revealed to have been at the scene of the party, hiding in the foliage and taking photographs, Tommy, Steve and Carol broke his camera and tore up his photographs.
Steve decided to check up on Nancy, as he was worried about her - Tommy and Carol teased him for caring. They drove to the Wheeler house, where Steve got out and climbed up the roof, aiming to enter Nancy's bedroom via the window. Steve saw Nancy and Jonathan together, and mistakenly came to the conclusion that they were sleeping together.
The next day, Steve, Tommy, Carol and Nicole graffiti-ed abusive, obscene slurs against the walls of the Hawk Theater. This led to a fist-fight, with Jonathan beating up Steve. The police came to the scene to arrest them all, but Steve, Tommy, Carol and Nicole escaped.
While outside a petrol station, Steve decided to turn his back on Tommy and Carol, deeming them to be "assholes". After Tommy threatened to fight him, Steve got in his car and drove off to apologize to Nancy and Jonathan.
After the arrival of Billy Hargrove, Tommy quickly becomes friends with him, as Billy outdoes Steve in terms of popularity. At Tina's Halloween Party, he dressed up as Johnny Lawrence from The Karate Kid.
Two days later, Tommy belittles and ridicules Steve after Nancy has dumped him and is shown laughing maliciously when Steve suddenly becomes aware that Nancy has gone off with Jonathan.
In 1985, Steve told Robin that Tommy H. would've made fun of Steve or wouldn't be prom king.
Tommy, like his girlfriend, Carol, is shown to be very shallow and mean-spirited, never missing an opportunity to ridicule Steve about his relationship with Nancy, ultimately resulting in Steve falling out with him.
He is particularly nasty to Jonathan Byers, making rude comments about his missing brother Will, speculating that Jonathan may have killed him. There seems to be no redeeming qualities about Tommy, being depicted as a one-dimensional bully. He is shown to be completely indifferent and unsympathetic about the disappearance of Barbara Holland.
The only thing that Tommy did in the series that could amount to an act of decency was during the fight between Jonathan and Steve. After initially goading Steve on to beat up Jonathan, Tommy soon realised that Steve was losing the fight badly, and was taking a severe beating from Jonathan. This prompted Tommy to attempt to intervene on Steve’s behalf, trying to pull Jonathan away and even plead with Jonathan to easen up as “(Steve) has had enough”. This act of decency, however, was quickly undone mere hours later. Although Tommy bought Steve painkillers and soda to ease the latter’s injuries, Tommy insisted that Steve owed him money for this. Then when Steve called his friends out for being jerks, Tommy instantly turns on Steve, threatening to beat him up worse than what Jonathan did.
It can be inferred that despite Tommy’s hatred of Jonathan Byers, he still acknowledged that Jonathan was a dangerous fighter and hence, it is unlikely that Tommy would ever have considered fighting Jonathan. Thus, despite Tommy accusing Steve of running away, it proves that ironically, Tommy is truly a coward in contrast to Steve who proved himself to be brave after all.
