The ultimate antagonist of the Stranger Things, Mind Flayer is the ruler of the upside-down. He was introduced in season 2 as the creature controlling Will’s mind. The creature had infiltrated his mind while he was abducted by the Demogorgon. Though it was shown that he had been locked away by Eleven in the second season, he is still a threat. The hideous creatures from the upside-down want nothing more than to destroy our world. He controls the vines, Demogorgon, and every other creature from his territory.

2. The Spider Monster is the next big threat

In season 3 of Stranger Things, this spider-like monster was introduced. He attacked the party at the Starcourt Mall. He is one of the biggest creatures so far to appear from the Upside-Down after the Mind Flayer. It was the tiniest piece left inside Will when Eleven closed the gate. It used the bodies of the Flayer to transform into a giant spider.


3. The Hospital Monster is scary in Stranger Things

They were killed by Nancy and Jonathan at the hospital and they transformed into a bloody pulp and attacked the couple. Till Eleven arrived and killed them. It was just as intelligent as it was scary. It was later absorbed by the Mind Flayer.

In the first season of Stranger Things, it is the creature that took Will into the Upside-Down and killed Barbara. Also, it is a scary creature with a petal-like mouth and sharp teeth. It is provoked by the smell of blood. The Demogorgon had a strong skin that was even bulletproof. It is hard to imagine that Eleven could beat it.

5. The Flayed were the agents of Mind Flayer

Though, they were not as scary as most creatures they served as spies of the Mind Flayer. They were humans that were corrupted by the mental powers of the Mind Flayer. After losing Will, he took over Billy to spy on Eleven and the others. There were other citizens that the monstrous being took over and caused a zombie-like attack. Also, he used them to sacrifice themselves for him.


6. Demodogs are quadrupedal Demogorgons

As Mind Flayer used them to save himself. Also, they are extremely strong and great diggers. And they are smart, fast, and agile.

7. Vines are just as dangerous

Though they are controlled by Mind Flayer, they were the ones that infiltrated Hawkins and ruined the city. The lead characters named the block tendrils, vines. They spread slowly and help the Mind Flayer expand its control. They are also the same creatures that had trapped Will and were inside him. This could be how Mind Flayer got into him.
