Harry Osborn (Spider-Man Films)

Harry Osborn is the tritagonist of the Spider-Man trilogy. He is Peter Parker's best friend, and the son of Norman Osborn.

First Movie
When he finds out that Spider-Man had fought and killed his father as the Green Goblin, Harry snaps, "What have you done?!" and tries to aim a pistol, but Spidey had disappeared. At the ensuing funeral, Harry tells Peter that he's the only family he has.

Second Movie
When he unmasks Spidey as Peter, Harry swore more revenge, by discovering his father's Goblin chamber, with bombs, performance enhancers and the Green Goblin suit.

Third Movie
Harry suits up as the New Goblin and attacks Peter, who tries to tell him what really happened, to the point of causing a coma. Later, Harry helps Spider-Man fight Venom, only to get stabbed by his own glider, just like his father. At his best friend's own funeral, Peter narrates, "Harry chose to be the best of himself. It's the choices that make us who we are, and we can always choose to do what's right."
