He first appears in American Pie where he attempts to offer sexual advice including purchasing and giving his son Jim pornography after finding him masturbating with a tube sock.
He helps to host the competition, which includes competing to remove girls' bras the fastest, a light saber duel and catching a greased pig, with the final challenge being to hold off from ejaculation while receiving a lap dance.
American Reunion marks Noah's last appearance in the franchise and reveals that his wife (otherwise known simply as "Jim's Mom") has died three years prior to the events portrayed in the film, and that he is still grieving her loss.
When Jim decides to turn on a porn movie that Stifler rented, he accidentally uses superglue instead of lubricant to masturbate, permanently gluing his entire hand to his penis and boxer shorts.
On the day of the wedding, Jim announces his appreciation and love for his friends Paul Finch, Kevin Myers and Steve Stifler and then happily marries Michelle.
Naked Mile also alludes to Jim's paternity as Noah proudly informs Erik, Steve and Matt's younger cousin, that Michelle successfully gave birth.
At the class reunion, Michelle shows up without telling Jim, and they both lightheartedly act like strangers before they go into the high school's band room and have sex on a desk.
After returning from his first year at Michigan State University with Oz, Stifler attempts a reunion party at his home, which is shut down thanks to the neighbors calling the police.
Throughout the film, he attempts to re-create his teenage years (such as seeking revenge on a group of mean-spirited teens and throwing one of his trademark parties) but fails each time as his friends and everyone else have outgrown this.
In a surprise turn of events, he meets Finch's gorgeous mother and finally has his revenge by having sex with her on the lacrosse field as the MILF Guys, John and Justin, happily watch.
Kevin Meyers first appears in American Pie as the suave leader of the pack, and he is the friend of Jim Levenstein, Chris "Oz" Ostreicher, Paul Finch, and Steve Stifler, and the boyfriend of Vicky.
Kevin reappears in American Pie 2 where he, Jim, Oz and Finch return to their hometown in East Great Falls, Michigan, for the summer break after their first year of college.
Together, they set off for a rented house by the beach in Grand Harbor, Michigan, where they intend to spend the whole summer, but Kevin is forced to invite Stifler along as well in order to successfully cover the costs.
As a groomsman, he aids Jim in finding the wedding dress Michelle finally settles on after long hours of searching, which is made by only one designer, Leslie Summers, working for one store.
Paul reappears in American Pie 2, where he, Jim, Kevin, Oz, and Stifler return to their hometown in East Great Falls, Michigan for the summer break after their first year of college.
Upon hearing that Cadence is hoping to attract a decent guy, Stifler adopts a more meek attitude and acts like Finch, and avoids swearing and speaks of philosophy.
Later, Stifler realizes that he actually feels bad about his previous actions, prompting him to bring in the football team he coaches to set up the entire room with new flowers.
Christopher Russell "Oz" Ostreicher first appears in American Pie as a member of the high school lacrosse team and as a friend of Jim Levenstein, Kevin Meyers, Steve Stifler, and Paul Finch.
Like the majority of the other characters (excluding Jim's Dad, Matt Stifler, and The Sherminator), Oz does not appear in any of the spin-off films, but his name can be seen on the check-out card for "The Bible" in The Book of Love.
Vicky appears at the five boys' lake house when they host one of their many parties, where she tells Oz and Kevin, while they're playing pool, that she had sex with only one guy whilst in college.
After Finch's reputation is destroyed due to a diarrhea incident at school, he meets up with headphone-wearing Jessica during prom, who hands him a $50 alcohol flask with his first initial engraved on it.
During the end-of-summer lake house party hosted by the guys, Jessica and Stifler share a sexually tense moment after expressing awe that Sherman is about to have sex with Nadia.
Matt was first introduced to the series alongside his elder brother watching Nadia, the foreign exchange student, strip-tease in Jim Levenstein's bed room.
However, as the summer progresses, Matt suddenly develops a friendship with his fellow campers and romantic feelings for the drum major Elyse, whom he had recently had an off screen relationship with prior.
Upon hearing that Cadence is hoping to attract a decent guy, Stifler adopts a more meek attitude and acts like Finch, and avoids swearing and speaks of philosophy.
He is a burly homosexual man who is a regular at a gay bar the boys unwittingly visit, to find a fashion designer named Leslie Sommers to make Michelle's wedding dress.
He takes great joy in both embarrassing and patronizing Oz, such as providing the DVD to his appearance on Celebrity Dance-Off in order to not only humiliate him but to make him look bad in front of Heather.
Whilst he is presented with several opportunities to have sex, Erik decides he only truly wants to lose it with Tracy, his girlfriend, causing him to ride a horse back to her house and inform her that he doesn't care what happens as long as he's with her.
The BETAs move into their new mansion, courtesy of the GEEKs, and hold a massive toga party, where Cooze, much to his relief, finally sleeps with Denise and all suspicions of her being a man are gone.
Though Girls' Rules received poor reviews,[6] Lizzie Broadway's portrayal of Stephanie Stifler was regarded as a high point of the film with Flickering Myth describing the character as 'as brash and opinionated as the OG, but with a likable feminist bite'.
