There was nothing Complicated about Richards' role: a bikini-clad beauty who fell for Slater's somehow-acceptable chauvinism — and, of course, his Jheri curl.
Tad Pogue, Saved By the Bell (Season 3, 1991)
Fifteen years before he stepped into the towel — I mean role — of Grey's Anatomy's Dr. Mark "McSteamy" Sloan, Dane was just another doof in a neon tank top making trouble for Zack and the gang.
Stacey Carosi, Saved By the Bell (Season 3, 1991)
In terms of guest stars, Remini's Stacey hardly qualifies as "obscure." In fact, while all true Bell fans ship Zack with Kelly, I'd say Stacey was a close second. But, oh, those summer nights…
Violet Anne Bickerstaff, Saved By the Bell (Seasons 2 & 3, 1990-1991)
Another not-so-obscure recurring character was future 90210er Spelling's Violet, who showed Screech — I mean "Samuel" — the kind of love and affection denied to him by that ice queen Lisa Turtle.
Simply "student," Saved By the Bell (Seasons 2 & 3, 1990-1991)
I've never heard the wolf cry to the blue corn moon (sorry, Pocahontas!), but thanks to Saved By The Bell, I have heard Scott Wolf howl in the Bayside High School glee club. The original Finn Hudson, he was.
Heather, Saved By the Bell (Season 3, 1991)
For some students, the S.A.T.s are a stressful time; For Zack, it was mating season. Poor Heather was too dumb to see through his game — and probably too dumb to even spell "S.A.T.," to be honest.
Chad Westerfield, Saved By the Bell: The New Class (Season 1, 1993)
Marsden's character pretended to like everyone in order to win Homecoming King, but his plans were foiled when his true (anti-"nerd") feelings were revealed. As expected, his character is so much more enjoyable on mute.
Simply "janitor", Saved By the Bell: The College Years
Presented without commentary. I won't even apologize for the poor quality of the image.
Mark Carlson, Saved By the Bell: The New Class (Season 7, 1999)
Clearly a precursor to his days on Covert Affairs, Gorham suited up for his New Class guest spot, in which he was admitted to the Honors Corps.
Greg, Saved By the Bell: The New Class (Season 4, 1996)
Before he was flirting with a Gilmore girl and being a hero and whatnot, Ventimiglia was just a hospital volunteer named Greg who couldn't nab a date to save his life. (So unrealistic!)
Sandy, Saved By the Bell: The New Class (Season 2, 1994)
No, your eyes don't deceive you; that's actually sharknado-survivor Tara Reid as a Bayside High School cheerleader. (You Chuck fans might also recognize Sarah Lancaster, a regular from Seasons 2 to 4.)
Nurse Penny Brady, Saved By the Bell: The New Class (Season 2, 1994)
Before falling for Xander over in Sunnydale, Caulfield had another dork — briefly — in her life: Screech! He fell for her when they met during a Bayside High blood drive. (Sure, blood she can handle, but not bunnies.)
Hilary & Jennifer, Saved By the Bell: The New Class (Seasons 3 & 4, 1995-1996)
Union made two appearances — as two different characters — during New Class' run. She might have been a Highlander, I'm not sure.
Soleil Moon Frye
Robin, Saved By the Bell (Season 4, 1992)
Now, I ain't sayin' Robin was a gold digger, but… actually I am. The former Punky Brewster took Screech for every penny he was worth, leaving him with an empty wallet — and a broken heart.
Megan Jones, Saved By the Bell (Seasons 1 & 2, 1993-1994)
And then there's Lawson, who was a regular for New Class' first two seasons, before going on to play (or at least look like) a high school-aged character in every TV show ever made. Her credits include: Buffy the Vampire Slayer, The Vampire Diaries, Pretty Little Liars, Teen Wolf and now Witches of East End.
