They are Edward Platypus' four older brothers who bully their younger brother and are the reason Edward is bitter to the other Bean Scouts and are more successful than him.
They are shown to be ruthless, mean, rude, bossy, and arrogant as they bullied all the campers at Camp Kidney (including their younger brother Edward) until Edward stood up to them in the end.
They were revealed to have been campers in "O Brother, Who Art Thou". Cheesly ruled Camp Kidney with an iron fist and played tetherball with the campers just like they did with their younger brother Edward, and he and his brothers got away with it by acting sycophantic towards Slinkman. When they returned to camp, after having badly abused their younger brother Edward like a scapegoat, they intimidated, threatened, bullied, teased, and harassed all the other campers as before.
Their new reign of terror ended when their younger brother Edward returned in the long lost Rotten Cabin, and after running over Alpine, sent them running back home.
- They are very similar to Eddy's Brother from Ed, Edd n Eddy.
- Both are older brothers and bullies to their younger brothers (Edward's Brothers to Edward and Eddy's Brother to Eddy).
- Both were revealed to be responsible for their younger brothers' negative personality.
- Both harassed their younger brothers for their whole lives.
- Both hate children.
- Both were revealed to bully younger kids their whole lives.
- Both were eventually defeated by their younger brothers' friends (Edward's Brothers by having Edward and his friends stand up to them and Eddy's Brother by having a door fly in his face by Ed).
- They are the reason why Edward acts so bitter in the series, as their cruelty and poor treatment towards Edward caused him to develop insecurities he has carried throughout the series, and feel the need to establish dominance over the campers.
