In the years since Tony Stark told the world he was Iron Man, the Marvel Cinematic Universe has introduced a huge cast of superheroes with a wide array of abilities.

From a genetically enhanced World War II soldier to a photon-blasting Kree-human hybrid, the MCU's decadelong saga has brought together the most ambitious super-powered team in cinematic history.

It has also inspired a lively debate about the strength of each character's abilities, and who would be considered the most formidable Avenger.

We rated every hero on a scale of 1 to 10 (with some exceptions) using evidence from the 22 interconnected MCU movies, including and especially "Avengers: Endgame." Here's our power ranking. (Note: This doesn't include details or storylines from the comics.)

This is your last chance to head back before "Endgame" spoilers.

28. Mantis

Abilities: As an empath, Mantis can read the emotions of others while touching them. She can also influence and alter their emotions, "to some extent," in her words.

Power scale: 1. Mantis' powers are quite potent. She was able to make Ego, an ancient and powerful Celestial, sleep against his will in "Guardians of the Galaxy 2." She was also instrumental in the near-defeat of Thanos in "Infinity War." But neither would have been possible without the help of other characters: In the former case, Drax carried her away from danger and saved her life; in the latter, Doctor Strange put her in place to subdue Thanos. Her skill set is extremely specific and, when it comes to most situations, not very useful.

27. Rocket

Abilities: Thanks to genetic enhancements, Rocket is extremely intelligent and far more durable than a regular raccoon.

Power scale: 1. Rocket is most useful in situations that require plotting, strategizing, laying traps, and manipulating science and technology. But in the thick of a battle, he's only useful so far as he can use a powerful gun. He was nearly crushed by an enemy ship at the end of "Endgame" and only survived because of Tony's snap.

26. Drax

Abilities: Drax has superhuman strength, durability, agility, and regenerative powers.

Power scale: 1. In theory, Drax is a great warrior. He was able to overpower most of Ronan's forces in "Guardians of the Galaxy." But, when compared with many of the Avengers, we haven't seen anything too impressive from him. Plus, he's not the brightest and his confidence is a bit over-inflated, so that has caused some problems (see: trying to attack Thanos alone in "Infinity War" and jumping inside of a monster's scary mouth in "Guardians of the Galaxy 2").
