Arite is Martin Smarty's bratty son with a rebellious attitude. He was placed under Ron's care so he can become a more respectable child. However, that didn't go so well; almost immediately he released all the Smarty Mart pets in the store. Despite his tough-as-nails attitude, he seemed to care greatly for a trio of otters; saving them from rampaging robots, then skating away. He also liked Ron's pet Rufus and Rufus seemed to like him too. He then later saved Ron, Kim, Barkin, Rufus and the otters from the robots, but said he only did it to save the otters and Rufus. His father then learned to love his son the way he was and wanted Artie to teach him how to skate. Later, while his father and Shego were watching TV he walked in and called Shego "new mom," which made her walk away warily.
Artie dresses in typical skater fashion; wearing a black shirt and a purple beanie with a skull on it. Also he wears plaid shorts with converse shoes and his skateboard is never very far from him. His ears are also pierced and he wears braces.
