[[WMG: Characters from ''WesternAnimation/TotalDrama'' are really some of the characters of ''6teen'''s doppelgangers.]]
* Jen and Courtney: Both are uptight, bossy [[TeamMom Team Moms]], and they even ''look'' alike.
** Only Courtney is worse.
* Izzy and Lydia: Both are psychopathic {{Yandere}}s.
* Jonesy and Duncan
* Wyatt and DJ
* Caitlyn and Lindsey
* Harold and Darth: They're both red-haired nerds with hidden talents. Each at one point got back at Jonesy/Duncan.
* Katie & Sadie and the Clones
* Nikki and Gwen: Both Goths.
* Heather and Tricia: Both are [[AlphaBitch Alpha Bitches]]

[[WMG: ''WesternAnimation/{{Stoked}}'' is an AlternateUniverse ''6teen''.]]
* ''WesternAnimation/{{Stoked}}'' takes place in the same universe as 6teen, just in different parts of the country (''Stoked'' in British Columbia, ''6teen'' in Ontario)

[[WMG: There is nothing outside THE MALL.]]
* The outside world of the mall is never shown. Employment opportunities outside the mall are never discussed. The mall seems to contain everything necessary to sustain life and society and hanging out at the mall seems to be every character's only pastime. The Mall is a giant arcology.
** There have been multiple scenes set outside the mall, including several set in the Masterson home and Jude's bedroom in "Dude of the Living Dead."
*** The masterson home is inside the mall. All those people live somewhere.

[[WMG: Nikki's family [[spoiler:moves back within a few months.]]]]
* In the GrandFinale, Nikki [[spoiler:unselfishly chose to go along with her parents' plans to move to Nunavut so that her father could get his dream job. Nikki has a very close circle of friends, including a very close boyfriend. There aren't many people in Nunavut, especially teens Nikki's age for her to get along with. To make a long story short, she'll be miserable. She'll try to put up a good front of being happy to support her parents, but, as good parents do, they'll see right through it. Nikki's father won't be able to enjoy his dream job with his daughter suffering, and his own job performance will suffer. He'll get fired and Nikki and her parents will move back, reuniting Nikki with her friends at the mall]].

[[WMG: All six members of the gang were reincarnated into [[WesternAnimation/MyLittlePonyFriendshipIsMagic the Mane 6]]]]
* Jen became Twilight Sparkle, Nikki became Rainbow Dash, Jonesy became Applejack, Wyatt became Fluttershy, Jude became Pinkie Pie, and Caitlin became Rarity.
* Alternately, Jonesy is Rainbow Dash because he is rather loud, and seems highly exited about sports. While Nikki is Applejack because of her sheer honesty, and strong disputes with whomever is Rarity.

[[WMG: Caitlin is actually a [[spoiler: SixthRangerTraitor]]]]
* Seeing as she never betrayed the gang and stayed their friend until the end of the show, this is pretty much {{Jossed}}.

[[WMG: The Girls of 6teen are based of the main ComicStrip/{{Garfield}} Characters]]
* Nikki is Garfield, Caitlin is Odie, and Jen is Jonathan Q. Arbuckle.
