In 'Spider-Man 3', what alias does Harry Osborn adopt as a villain?

In “Spider-Man 3,” Harry Osborn adopts the villain alias New Goblin. After his father Norman dies as the Green Goblin, Harry blames Spider-Man for the tragedy and becomes obsessed with revenge.

Harry uses technology inherited from his father, including a glider and weapons integrated into a new combat suit. Unlike Norman, he does not rely on the same goblin serum; his abilities come primarily from advanced equipment and his own training.

The name can cause confusion because Harry is sometimes associated with the Green Goblin or Hobgoblin in other Spider-Man stories. In the 2007 film, however, the character is identified in the credits and promotional material as the New Goblin. He eventually remembers his friendship with Peter Parker and joins him against Sandman and Venom.
