He is a drug dealer. He sold the HFS to students without getting caught. He is a popular student, and is good friends with Molly, Juario, and other students. He lives in a mansion, where Morton went to see him. Morton Schmidt acts as a fellow drug dealer, though gives it to be confiscated. Morton and Jenko then find out that they are dealing with the One Percenters, which turns into a fight against the One Percenters. They find the supplier and it becomes a large battle against the drug dealers. Eric is arrested at the end of the movie. In 22 Jump Street, Eric is now in jail with Mr. Walters , who is in a forced 'relationship' with Eric, who considers Mr. Walters to be his "bitch".
Eric is a modern day hippie so to speak, he is very calm for the most part , but later on freaks out after his life may be turned around for the worse. He doesn't seem to care about his relationship with Molly, especially when he suspects Doug is texting her. Later on in prison, he reveals to be a forced homosexual and also seems agitated with Mr. Walters, as Eric doesn't like it when Mr. Walters considers himself to be his "Bitch". Eric possibly got Mr. Walters pregnant due to Mr. Walters having a vagina and Eric having sex with him. At the last scene of 22 Jump Street, We see Eric about to cry. Maybe because he is excited for his new daughter or son because he is having a daughter with a man or because he's gonna be a dad soon. He ended up having a daughter. Bro I'm sorry who the hell wrote that? Mr. Walters cannot physically get pregnant. He didn't have a kid. Eric is crying at the end because he's about to get raped.
Despite the fact that Eric is the secondary antagonist, he was the main antagonist for the majority of the film, but when Domingo emerge by action and Mr. Walters by having more bigger plans than everyone else, Eric is demoted to be The Heavy mainly because he was truly responsible for the HFS drug trade going viral.
