Will Stronghold

William Theodore "Will" Stronghold is the protagonist of Sky High, as well as the narrator of the film's opening and ending. He is the son of a famous superhero couple, the Commander and Jetstream, but does not seem to have inherited any powers until mid-film.

Personality
Will is depicted as a loyal and kind person, who values friendship and family more than pride of being a superhero. In the beginning of the film, he was completely distraught by the possibility that he may never inherit any powers, as a nurse discussed some rare cases whereas the child of two super-powered parents might never acquire any of their powers though they might activate later. He taps into his dormant power of super-strength when his arch-enemy, Warren Peace, threatens to attack his friends, forcing him to unleash the hero within; although this comes as a shock, he is overly excited by his new powers.

His popularity status escalates greatly after this, but also at the cost of his friendship to Layla, Magenta, Zach and Ethan. In the end, he puts friendship over pride and apologizes to his friends for his behavior. His partnership with Warren Peace eventually allows them to develop a close friendship, and his friendship with Layla escalates into a romantic relationship.
