Kim Possible's best friend and sidekick. The two of them have known each other since pre-school, and have been best friends for most of their lives. Ron Stoppable is easy-going, cheerful, and kind-hearted, but also extremely clumsy, goofy, and lacking in common sense. Kim Possible sometimes gets impatient with his randomness and weirdness, but thanks to his kind heart over the years she's learned to tolerate and accept it. Although Ron Stoppable is extremely extroverted, Kim Possible appears to be his only real friend, as most other kids are put off by his sheer randomness. His motto is "never be normal," as stated in the beginning of the first episode, Crush. The polar opposite of Kim Possible, Ron Stoppable is extremely accepting and seems totally unconcerned with appearance and peer pressure. However, he is afraid of practically everything else (including monkeys, although he has slowly managed to overcome this), and as such, he's had to constantly overcome his various fears.
On missions, Kim Possible usually uses him as a distraction, since he seems like he couldn't hit someone if his life depended on it (which it usually does). This may be due more to an aversion to violence rather than a lack of skill; Ron Stoppable has shown to be quite gifted in the "Monkey Kung Fu" skill (Tai Shing Pek Kwar) introduced by Monkey Fist (whom Ron Stoppable once defeated without any help), and Ron Stoppable has proven highly formidable on the few occasions he's been motivated to actually fight an enemy. During his time at Yamonuchi, a ninja school in Japan, Ron Stoppable was found to be worthy of the mystical Lotus Blade, which can take on the form of multiple weapons and be summoned at will. Ron Stoppable is also very good at dodging things, and on two separate occasions he's managed to successfully evade the combined attacks of both Kim Possible and Shego. He also has incredible amounts of dumb luck (which he calls "dumb skill"), and in a Clouseau-esque manner often manages to bumblingly help save the day by sheer accident.
Ron Stoppable's greatest interests are Tex-Mex food and video games. As a running gag, he has a tendency to have his pants ripped off by random accidents, as well as a tendency to come up with bizarre, paranoid theories that turn out to be totally false (such as mistaking Dr. Drakken's plot to build an army of killer robots as a plot to steal Christmas).
Although he often appears to be somewhat clueless and thick-headed, this is only because he's usually so random and unfocused. On the rare occasions when he's been motivated to concentrate on something, he's actually proven to be quite bright. He once built a doomsday machine out of random junk after being kidnapped by Drakken. Later, after a mishap that caused him to turn evil, he proved even more dangerous than Drakken by commanding fear and respect from Shego and almost succeeding in destroying the world.
Ron Stoppable is also an accomplished chef, and is reknowned as the inventor of the Naco. He has also opened a restaurant in Middleton High's Home Ec room, where he was booked solid months in advanced. Unfortunately the Board of Health shut him down when they discovered a live rodent, Rufus, serving the food.
He is also the Middleton High mascot, for which he wears a full-head Mad Dog mask with a working foam generator which he made himself.
Ron Stoppable spends much of the series trying to win other girls' affection, usually unsuccessfully. One or two have returned interest, though Ron Stoppable didn't notice until it was too late. Ultimately, he ends up pairing up with Kim Possible.
