Roger Klotz is the school bully in the Nickelodeon/Disney animated series, Doug.
Roger is the local bully in both Bluffington Elementary School and Beebe Bluff Middle School. The main object of his bullying is Doug Funnie, ever since Doug first moved to town and got ketchup on his boots when they first met. Despite being a bully, he can be friendly at times, and is more of a friend to Doug in the Disney episodes, but still has some of his antagonistic traits. In one episode of the Nickelodeon seasons, Roger was bullied by Mr. Bone's nephew Percy Femur, leading to having Doug defend him before Mr. Bone found out about his nephew being a jerk.
He lived with his mom and his cat, Stinky, in a trailer in Bluffington, until his mom sold the land for a large amount of money, and moved into a mansion, becoming the arch-rival of Beebe Bluff in terms of money. His mom and dad are divorced, and his dad lives in Bloatsburg (where Doug originally lived).
Roger's closest friends are Ned Cauphee, Boomer Bledsoe, and Willy White, who are often seen around him. They make up his gang, but are usually nicer than him (though this is usually when he's not around). Later on in the series, Roger develops a crush on Patti Mayonnaise and he and Doug begin to compete for her attention.
According to the episode "Doug Graduates" (from Nickelodeon), he has been in the sixth grade for three years (counting the year the show takes place), making him two years older than Doug.
- Connie Benge has a secret crush on him in the Disney series as revealed in a Disney Adventures issue.

- His catchphrase is "Joeykookamonga!" and it made its first appearance in "Doug's in the Money", it became his permanent one in "Doug's New School".
- Along with Doug, Roger was one of the only characters in the Disney series to get a new voice actor, though his new voice was not as poorly received as Doug's, since Roger's new voice actor (Chris Phillips) sounded closer to Roger's original voice (Billy West).
- In the live show he had his old outfit.
- In a Nick episode, when Bone dumped water on everybody's heads, you may notice his hair looks like his Disney hairstyle when it was wet.
