Gary
Gary is a recurring character on Stuart Fails to Save the Universe who appears as Denise’s boyfriend in multiple universes, becoming what Stuart comes to see as a running joke in their multiverse catastrophe.
When we meet Gary in the post-apocalyptic reality of 101 “Spoiler: Gary Dies”, Gary and Denise are a couple surviving on the streets of Pasadena by mugging passers-by. Denise began a relationship with Gary after believing Stuart had died in the apocalypse, while Gary had been dating Denise’s friend Lisa, who was eaten by cannibals in Sherman Oaks.
After Stuart and Bert explain that an alternate version of Stuart has sent them on a mission to Caltech to undo the apocalypse, Gary and Denise are sure Stuart and Bert are about to die. After catching up with them outside Caltech’s heavily armed perimeter, Gary suggests creating a diversion so the others can sneak in under supply trucks. When Bert comments that Gary has done this before, Gary reveals he was in the Army Special Forces. The diversion ends almost as soon as it begins: Gary is killed immediately after stepping out, leaving Denise devastated.
When we meet Gary in the AI-controlled reality of 102 “Spoiler: Zack's in This One”, he is once again Denise’s boyfriend. After Stuart tracks this universe’s Denise down and finds her with Gary again, he concludes that Gary is part of a running joke the multiverse is playing on him.
Unlike his rugged post-apocalyptic counterpart with a history in the Army Special Forces, this version of Gary is clean-cut and preppy. He is oddly accommodating when Stuart arrives to “claim” Denise, because the AI-controlled society has trained people to avoid upsetting each other. Gary openly admits that Denise cannot stand him, while Denise confirms that she only stays because leaving him would traumatize him and trigger the implants in their necks. Gary is content staying with Denise because she is only unhappy when she is sober, and that is not very often.
After Denise learns that Stuart was telling the truth about the vari-state quantum interference device, she leaves Gary and joins Stuart, Bert and Kripke. This version of Gary is left behind in the AI-controlled reality, while Denise travels with Stuart into the next reality.
