Characters see a tv which shows live news reports about a guy that walks around the city streets followed by a crowd and on camera challenges some other guy to come fight him. His nickname is something about that he likes to fight, like a Brawler or similar, he probably had shoulder lenght hair and overall it was reminescent of how the movie They Live looked.
Rocky V has a guy that looks like that and he calls out Rocky to fight himHis name was Tommy “Machine” Gunn.
