Linus Williams is the main protagonist of the Disney animated film Devil Dinosaur.


When he was two years old, Linus was diagnosed with high-functioning autism. His childhood wasn't much of an easy one; his short-tempered father often treated Linus harshly because of his symptoms. 

When Linus was seven, his father decided that he wanted nothing to with his autistic son & so, consequently, he left him & his mother. This altering moment in his life resulted in Linus's mother raising him. 

Over the next years, Linus was able to use the assets connected with his autism to help him excel in school. During those years, he became friends with Kyra Collins, who was a year older than him. He also developed a love for science fiction & all things mysterious.

After graduating high school, Linus, along with Kyra, started attending the University of New York.

Official Description

Many people think his ideas are crazy. Little does college student Linus Williams realizes that what he was just fiction is about to become a thrilling adventure!


Due to high-functioning autism, Linus usually has trouble understanding & communicating with others. Although he wishes to be more social, too often Linus tends to be withdrawn from people, usually being by himself. He also tends to get all moody, pessimistic, & is prone to anger outbursts.

Of course, being autistic also has its benefits. While his intelligence is at an average level, Linus can focus on things & has an incredible imagination. As a lover & expert of science fiction, he is interested in all things mysterious, always seeking truth in fiction.

Linus is a sweet-natured young man who is always seeking to be loyal & reliable in the best way he can. Of course, there are times when he tends to get all socially awkward. While he doesn't want to be seen as a wuss, Linus tends to get a little hesitant in doing extreme challenges. For example, due to being sensitive to cold water, he tends to be a little uncomfortable, like whenever he's on a canoe in the middle of a large body of water, as he's afraid of falling in.
