As fans quickly noticed, the Stranger Things season 5 finale episode was lacking some demogorgons and demodogs, but their notable absence was not always the plan. According to the Duffer Brothers, at some point there was a three-hour version of the ending which included not only Vecna's loyal creatures, but also an Aliens reference.
During an interview with The Wrap, the Stranger Things showrunners were asked to clarify where the demogorgons were when the gang arrives at The Abyss in the last episode of the fifth season (you can read all about what happened there in our Stranger Things season 5 finale ending explained). "Mainly it’s just that Vecna was not expecting this sneak attack on his home turf. Never in a million years could he even imagine that," Matt Duffer answered.
