Tom J. Hanniger is the hidden true main antagonist in the 2009 3D slasher remake film My Bloody Valentine (also known as My Bloody Valentine 3D).
He was portrayed by hit television star and CW natural Jensen Ackles, who also portrays Dean Winchester.
In the beginning, he was nice and had a girlfriend until a year later on Valentine's Day, Warden wakes from his coma in the hospital and goes on a murderous rampage at the abandoned mineshaft where there is a party, attended by many teens including Axel Palmer, his girlfriend, Irene, Tom Hanniger and his girlfriend, Sarah.
Tom was initially reluctant to go to the mine party, but he goes anyway. He leaves Sarah and goes back to his car to pick up some beers before departing inside.
Sarah goes in alone and gets lost looking for Axel and Irene. She runs across a teen and a few seconds later he is stabbed through his eye.
She is confronted by Warden in full miner's garb, carrying a bloody pickaxe, and she flees, finding several dead bodies.
Axel grabs her and they, along with Irene, hide from the killer. Warden eventually sees the trio, and they run out of the mine, meeting Tom as he comes in. Warden hits Tom with the pickaxe, injuring him, while the other three run for the car.
Tom spots them, but Axel escapes with Sarah and Irene, abandoning Tom. Tom runs back into the mine in an attempt to escape Warden. Before Tom can be killed, the police arrive and shoot Warden who makes his getaway back into the mine. Tom also appears shocked by the events.
After 10 years, Tom came back home after his father's funeral to sell the mine, having vanished since the incident and it was unknown where he was since he was devastated by the events and unable to see Axel and Sarah after they had abandoned him in the mine to die.
