Mutt Williams

Henry "Mutt" Williams was the son of Marion Ravenwood and Indiana Jones. In 1957, he accompanied Jones, Mac and Ravenwood on a quest for a crystal skull. He carried a switchblade and rode a motorcycle.

Biography
After Indiana Jones left Marion Ravenwood a week before their wedding, she gave birth to a son who she named Henry Jones III. Marion went on to marry Colin Williams who Mutt was led to believe was his biological father. Mutt also befriended Professor Harold Oxley, who became a surrogate father to him when Colin was killed during World War II.

When Oxley went missing in Peru, Marion followed and ended up disappearing as well. She managed to get a letter to her son telling Mutt to find Jones. He caught up the archaeologist just as he was leaving on a train to New York City, having decided to leave the country for London.

After convincing Indiana to come along with him, they go to a diner, where Mutt delivers a letter sent by his mother, "Mary Williams". But then two KGB agents who were watching tried to capture the duo, only being stopped by Mutt starting a fight between the Greasers and Socialites. The archaeologist and his new sidekick get away on Mutt's motorcycle, and a chase through the Marshall College campus begins, ending when one of the two persuing Russian cars crashes into the statue memorial of Marcus Brody.

After Indiana and Mutt solve the riddles written in dead language from the letter, they go to the possible location of Oxley - Nazca, Peru.

Behind the scenes
The character was portrayed by Shia LaBeouf in Indiana Jones and the Kingdom of the Crystal Skull.

Though it was long-rumored Mutt is Indiana's son, Spielberg laughed off the idea: "I wouldn't say it's a father-son story. The new Indy movie is about a great quest, an amazing quest &mdash; and that’s all I’m gonna say.". Indiana Jones: The Ultimate Guide by Dorling Kindersely details Mutt as the son of Marion Ravenwood, a detail mentioned explicitly in LaBeouf's foreword only, and a Royal Air Force pilot named Colin Williams.

There is a touch of irony in Mutt's chosen name. Like his father Indiana, he dispised his birth name, choosing a nickname of his liking. Indy chose the name of his beloved dog from childhood. Mutt chose a slang term for a dog (a mutt is a dog of two different breedings), which also indicates that he has two different parents.
