Saved by the Bell has become notorious for introducing characters that disappear forever. Let’s list some of the most famous examples: Jessie’s step-brother, Eric Tramer, agrees to live with Jessie permanently but never reappears. Screech’s girlfriend, Violet Bickerstaff, disappears halfway through season three. Laura, a homeless girl and Zack’s love interest in “Saved by the Bell: Home for Christmas: Part 1 and Part 2,” lives with the Morris family until her father finds a job, but is never mentioned or seen again.
Even “main” cast member Tori Scott joins at the beginning of season four, appears sporadically, and then disappears before the graduation episode – though that was partially due to the order in which episodes were filmed.
Named After an Executive
In a well-known episode, geeky Screech builds a functioning robot. While the robot only appeared in three episodes, it was a famous detail of the character, and one of the ways he set himself apart from the other members of the cast – none of the other principal cast members could have done such a thing, that's for sure (except for maybe Jessie if it was for extra credit).
The robot's name was Kevin, which was the name of the NBC executive who was in charge of the show. While we have on the confirmation, we like to imagine the executive loved getting his name in the show in such a way.
Worked with Miss Bliss
Leanna Creel, who played Tori in the fourth season, might not have appeared in "Good Morning, Miss Bliss," but she did act with Miss Bliss's actress, Hayley Mills. Leanna, as well as her triplet sisters Joy and Monica, appeared with Mills in two of the three television sequels to the original "Parent Trap," almost thirty years after the original was released.
The Creel sisters appeared in "Parent Trap III" and "Parent Trap: Hawaiian Honeymoon." Both movies premiered in 1989, the same year Saved by the Bell made its debut. Hayley Mills was the actress who played both twins in the original "Parent Trap" and sings a duet with herself.
Magic to The Max
One of the most famous sets in the show – and indeed in pop-culture – is “The Max,” the diner where the gang would hang out after school. Several of the characters got part-time jobs there, the vivid decorating style became a classic symbol of the late eighties and early nineties, and the owner Max loved his magic.
In fact, Ed Alonzo, who played Max, is a real stage magician and illusionist – he even helped create special illusions for Britney Spears and her 2009 “Circus” tour. While he never does anything too crazy for the show, he's always ready to show off. However, Max never appeared after the second season for what is being called “Proto #MeToo allegations.”
The Almighty Time-Out
Somehow, for some reason, Zack Morris has a superpower. Just by yelling “Time Out!” he can freeze time for everyone but himself. He would use this opportunity to speak directly to the audience, move people around, get out of sticky situations, and get into more mischief. It was an especially weird part of a show with plenty of it, though it was much more common in the earlier seasons.
Zack's ability to do this is never really explained in-universe, though some commentators have noted it makes Zack into an almost deific character, especially that of a trickster God such as Loki, due to his manipulation, but is unable to handle even a taste of power. Only once is a character not frozen when Zack yells Time Out: Screech, in the glee club episode of season two.
