Gwen in alternate universes

--Spin To Win or Lose Gwen--
Being a spin-off of Spin To Win or Lose and the sequel Rocket To Insanity, STWoL Gwen appears in the very first episode. She competes against the contestants in a Family Feud crossover universe. Later in the episode, she bumps into a wall while flying and falls on Gwen. Gwen gains her memories.

In "Fresh, Sparkling Ignorance", she warns the others about the changes to the timeline caused by burning the cabins. She also mentioned another altered timeline, although does not go into detail. Presumably, it is either a universe where Gwen and Bridgette's plans won the challenge (as they were technically still in the past), or a timeline where Harold died for real.

she also appears in "finished cluster of chaos", when everyone goes to the STWoL universe for a meatball-finding challenge. she flyed gwen into the air when she came, and she flyed right behind gwen during the entire rest of the episode. she also gave gwen a necklace.

in "downtime plus elimination 9", she briefly appeared to grab gwen after her elimination. to everyone else, it looked like gwen just vanished into thin air. gwen did not see her coming, but presumably remembered it from both sides shortly after.

--Friday Night Funkin' Gwen--
When the contestants went to the FNF universe, Gwen met FNF Gwen (who is from a video), who sits on a speaker alot and runs a "Dance Dance Revolution"-esque game with FNF Trent and FNF Duncan. she immediately receives one of Gwen's memories of Camp Wawanakwa. She then asks Gwen about it. having gained Gwen's memory of gaining STWoL Gwen's memories, she touches Gwen's arm to get the rest of her memories. (and presumably getting STWoL Gwen's memories in the process.) Gwen receives FNF Gwen's only memory, which is the song in the video. presumably gwen danced so well because of this shared memory.

--MALE GWEN--
A male version of gwen appears in the gender-bent universe episode. he doesnt do much in the episode, but he shows gwen around and eventually they share their brain too.
