"Stranger Things" Season 5, Volume 2 finally reveals the origins of the Upside Down. Here’s how the wormhole works, what the Abyss is and how it all connects to Vecna.

The town of Hawkins is under attack from its greatest threat yet... puppies! Will the Stranger Things cast be able to defend their hometown, or will they succumb to the powers of these unstoppable furry creatures?

Stranger Things Season 5 is gearing up to it's finale. If you're an avid Stranger Things fan, you know that the Upside Down and its mysterious creatures (especially Vecna) have been the number 1 villain for Team Hawkins.

Stranger Things has been hinting at this reveal throughout Season 5. Look no further than its references to A Wrinkle in Time, which features wormhole-like tesseracts. Or how about Mr. Clarke fully teaching a class on Einstein-Rosen Bridges, aka wormholes?

Here’s what happens to Holly Wheeler in Stranger Things Season 5, including her abduction by Vecna and whether she escapes the Upside Down.

The claw-like structure has 12 long extended "fingers" shooting into the air, which fans are actually convinced are the Mind Flayer's limbs. You see the creature is seemingly inspired by a spider, which means that if it were dead per se, it would curl up on its back in the same way that a dead spider might.

Stranger Things has a canon stage play, First Shadow, that reveals the truth about how Vecna got his otherworldly powers.

This scene links back to Stranger Things: The First Shadow stage play, which goes deep into Henry Creel's backstory, making it canon to the Netflix blockbuster. The stage play premiered in 2023, almost two years before Season 5 ever premiered on Netflix, making this an extremely bold step on Netflix and the Duffer brothers' parts.

The "Stranger Things" euphoria is at an all-time high, as Netflix's record-breaking show is nearing its end. After five seasons, the series will come to an end on December 31 with its eighth and final episode.
