Ron and Kim have been best friends since pre-k. He also serves as her sidekick whenever they go on missions. Even though Ron is depicted as a clumsy goofball teenager, he has saved the world on his own. His name was a play on the word "unstoppable." He is not as popular as Kim and is often ridiculed by his classmates, most notably by Bonnie Rockwaller. A running gag in the series is that Ron often loses his pants during missions. He joined the football team in his senior year, having previously served as team mascot. He has a younger adopted sister from Japan named Hana. His favorite restaurant is Bueno Nacho and is the creator of the Naco. He is extremely afraid of monkeys, and small bugs, among (many) other things; Ron's fear of monkeys reduces as the series progresses and Ron matures. Ron is an exceptionally brilliant villain when he is turned evil.
