Hero's Theme – Angel in the night (Basshunter) An hip, modern kind of guy, who is still in love with his ex-girlfriend
Side Kick's Theme – Don't wanna stop (Good Charlotte) A more reclusive guy, who's in a relationship that he's unsure of but can't think of leaving it.
Love Interest's Theme – Wake me up when September ends (Green Day) A morose girl, quite quiet when you first meet her but with a deep, emotional core. She was hurt badly in the past, and still suffers from it such that when any good times start to fade she tries to hide from it, only to come out when everything's gone to shit again.
Antagonist's Theme – Espionage (Green Day) A highly skilled, well-educated agent, working for some corrupt businessman or agency of some kind. Think the spy from Team Fortress.
Final Battle Theme – Awake and Alive (Skillet) The antagonist uses mind games to mess with the hero's heads. He shows them that to the world, the hero is a criminal and the antagonist's boss is a well respected member of society, and he has no chance of winning. Eventually they break out of his control and beat him.
Return Home Theme – Accidental Death (Rilo Kiley) When the hero arrive home someone mistakes him for the antagonist and shoots him, he then has a flash back of his life while he slowly bleeds to death. Whether his friends manage to save him is unknown...
Well, that's depressing...
