Tonto

Tonto is the deuteragonist of the Disney's 2013 film The Lone Ranger. He is portrayed by Johnny Depp.

Official Disney Bio
A wandering Comanche, cast out from his tribe, Tonto rides alone in search of the two men responsible for the ruin of his village until his path fatefully crosses with that of the wounded young lawyer John Reid, whom he transforms into the Lone Ranger.

Physical Appearance
Tonto is a Native American, tanned man of average height. He has long black hair that reaches over his chest. He has white face paint with several black stripes vertically down from his eyes. He wears a headband with a black crow on it. He wears brown Indian pants, shoes, and several gadgets on his belt, including a little bag.

Lone Ranger
As a young boy, Tonto rescued brothers Butch Cavendish and Tom Wilkinson from near-death. He brought them back to his tribe to recuperate, and while there, they found a rock of silver in the river, and traded Tonto a silver watch to show them where the silver came from, turning out to be the greatest silver mine in history. The brothers then murdered the entire tribe to keep the secret. Unable to bear the burden of his role in the massacre, Tonto told himself that the silver had possessed the brothers, keeps the pocket watch as a sign of his bad trade, and keeps his dead pet bird on his head in hopes it will return to life once he atones for his sins.

Years later, Tonto is being transported to jail via train, alongside Butch Cavendish, who is being transported for his hanging after being apprehended. Cavendish's gang, however, hijacks the train, which derails soon after, resulting in Butch escaping and Tonto's arrest by John Reid and his older brother Dan.

Tonto escapes and comes across the rangers, who were killed by Cavendish's gang, a white spirit horse comes and walks up to John, though Tonto tries to convince him to go to Dan instead. When Reid is revived, he is informed by Tonto of his new status as a "spirit walker" (one that has been to the other side), and reveals that he cannot be killed in battle. Tonto also confirms that Collins (one of the 6 original Rangers) betrayed Dan and is working alongside Cavendish, a "wendigo". Reid and Tonto hunt for Butch and his gang throughout the desert with a white horse, which is believed to be sacred by the Indians.

Inspector Gadget
Tonto also appeared in the movie Inspector Gadget in the "Minions Anonymous" meeting, as he can be considered a minion of the Lone Ranger
