A Demogorgon from Stranger Things is portrayed as extremely strong , easily above peak-human level and closer to what you’d expect from a cinematic monster or “mini-boss” creature.

Physical power

  • It can overpower and carry away full-grown humans with one arm, smash through doors, and ragdoll multiple people at once, putting it well beyond realistic human strength.
  • Its body is heavily muscled and extremely fast, able to pounce several meters in a single leap and close distance before most people can react.

Durability and toughness

  • Demogorgons shrug off small-arms fire for a while, only going down after sustained gunfire, fire, or explosives, which suggests very high durability compared to humans.
  • Their hide can deflect or partially resist bullets, and they keep fighting even with serious injuries, similar to a large apex predator pushed into a frenzy.

Other abilities that boost “strength”

  • They have a strong regenerative factor and can keep functioning through damage that would kill a human, making them functionally “stronger” over the course of a fight.
  • Some versions are linked into a psychic hive mind controlled by Vecna/Mind Flayer, which can enhance their aggression and let them ignore pain or fear in combat.

How this compares in vs-style terms

  • In a versus scenario, a single adult Demogorgon is roughly on the level of:
    • A high-end movie slasher/monster that can break doors and tank bullets
    • Much stronger and tougher than any unarmed human, but still killable with concentrated modern weapons and good tactics

TL;DR: A Demogorgon is superhumanly strong (door-smashing, human-flinging, bullet-tanking predator), far beyond any human athlete, but not invincible and can be brought down by focused fire or heavy damage.
