Cubsrule2040's AGK Series is all about mainly Leopold Slikk.
His last AGK parody was uploaded 3 years ago, and now he mainly makes elevator and GoAnimate stuffs.
He has all of his AGK videos removed.
- Leopold Slikk - The main character, a 14-year old troublemaker. Leopold only cares about video games, especially Unreal Tournament, and things that he likes. He hates school and fails every subject. He is constantly getting into trouble, causing him to be grounded by his parents and getting suspension and detention. In many episodes, when he is in the principal's office, he smashes the phone to prevent the principal from informing his parents. His favorite foods are sausage eggs and the filet-o-fish sandwich.
- Leonard Slikk - Leopold's youngest brother. He gets good grades in school, unlike Leopold who gets all F's.
- Harold Slikk - Leopold's abusive dad. He always punishes and grounds Leopold for causing trouble at school and failing every assignment and exam. He gets mad easily at work, causing him to break his computer; he was fired from a job. His name originally was Hector but changed it to Harold sometime between the 16th and 17th episodes.
- Kathy Slikk - Leopold's mom. She punishes Leopold for creating trouble at school.
- Mrs. Konay - Leopold's teacher for all of his subjects.
- Mr. TissenCrupp - the first principal of Leopold's school. Each time Leopold does something bad at school, he gives him detention, suspension, in-school suspension, and informs his parents; however, Leopold often deprives Mr. TissenCrupp of the latter by smashing both the phone in his office and his computer keyboard. But he would give Leopold a longer suspension/detention time for smashing the phone in his office. He was fired after Leopold failed the Dumb Test and was replaced by Principal Beckwith.
- Mr. Beckwith - the second and current principal of Leopold's school. He became the school's next principal after Mr. TissenCrupp got fired. Like his predecessor, Mr, Beckwith suspends Leopold but also forces him to serve detention.
- Ronald Ramirez - the Angry Dominican Kid. Originally from the Dominican Republic, he moved to Germany after getting expelled from school. Initially Leopold and Ronald had arguments over which game was better between Halo 3 and Unreal Tournament. However, Leopold decided he liked Halo 3 and became good friends with Ronald. Like Leopold, Ronald hates school and fails every subject, and only likes playing video games.
- Adolf Hitler - Leopold's first substitute teacher after Mrs. Kone temporarily quit teaching. Leopold pulled a prank on him by building a robot that looked like Hitler himself and had the robot send hate messages to the students, causing Hitler to get arrested
- Hayden Panettiere - Leopold's second substitute teacher.
