There are all manner of superheroes in the Marvel Cinematic Universe. There are the regular, highly-trained or gifted humans like Tony Stark, Hawkeye, Black Widow and the Agents of S.H.I.E.L.D.; you have the super-power lot like Luke Cage, Captain America and Jessica Jones; and you have those who were created due to scientific accidents like the Incredible Hulk, Spider-Man and Daredevil. Then, there are all those that come from space and other dimensions -- Asgardian gods, Celestials, magic-imbued wizards, living weapons, and powerful alien beings and Inhumans. No matter where you find yourself in the MCU, from the streets of New York to the far reaches of space, you are bound to run into one super-powered individual or another.

But that's not all that there is out there -- there are also many artificial intelligence programs and robots that you could come across. Throughout over 18 movies and multiple seasons of various television shows on different platforms, from the world of the Guardians of the Galaxy to Tony Stark's workshop, we have seen many robot characters in the MCU -- perhaps even more than you thought. Some were considerably powerful, while others significantly less so. But which is the most powerful, and which would get pulverized in an instant? There's only one way to find out! CBR hops from the television side of the MCU to the world of the Avengers to list 15 robots that we have seen in action, and ranks them from the least formidable to the most powerful. Let the honest-to-goodness, all-out robot slugfest begin.

15 MAINFRAME

Mainframe has a very, very brief appearance in the Marvel Cinematic Universe. You can glimpse her in the closing scene of Guardians of the Galaxy Vol. 2, and a bit more importantly in one of the mid-credits scenes of that film. She is a member of Stakar's original team of Guardians.

This robot is effectively nothing more than a metal head voiced by Miley Cyrus. While her name suggests that she might be adept at hacking other circuit systems, the fact that Mainframe is just a head makes her an easy target for the rest of the MCU's robots. Until we know more about the character, she appears to be all brains and no brawn.

14 HAMMER DRONES

The HAMMER drones appeared at the end of Iron Man 2. They were originally designed by Justin Hammer to be an entire fleet of Iron Man-like suits for the military to wear. However, Hammer made a deal with the devil when he drafted Ivan Vanko onto his operation. The villain known as Whiplash took over the project, and made a few changes.

Vanko changed the design of the suits so that they could be turned into remote-controlled drones that he could dispatch however he pleased. The HAMMER drones had all of the firepower at the company's disposal, which made them dangerous to the public – but quite easy for Iron Man and War Machine to take care of.

13 DUM-E

DUM-E is the very first robot that we encountered in the MCU in 2008's Iron Man. It was introduced as Tony Stark's helping hand inside of his workshop. It was his mechanic and devoted assistant, no matter how often the genius-billionaire-playboy-philanthropist made fun of it. In fact, DUM-E was so instrumental that it saved the life of Tony Stark near the end of the film.

The robot may not be the most powerful in the MCU, but it is devoted and it has shown that it has a knack for survival. It survived the destruction of Tony Stark's mansion, and it was still seen lending a hand in Spider-Man: Homecoming. DUM-E is not to be understimated.

12 THE IRON LEGION

The Iron Legion was introduced at the beginning of Avengers: Age of Ultron. An army of remote-controlled Iron Men, the Legion was dispatched by J.A.R.V.I.S. to lend a helping hand to the Avengers' efforts in all manner of super-heroics. They have all the basic powers of the Iron Man suits, and no man inside to pilot them.

Once these suits of armor were controlled by Ultron, the Legion proved just how powerful they were by attacking the Avengers and giving them one hell of a fight. Essentially, the Avengers were battling a small army of Iron Men, and they proved very difficult to put down.

11 HUMAN TORCH

Wait, the Human Torch? Yes, the Human Torch, but not that Human Torch. In the Marvel comic books, there was another Human Torch besides the Fantastic Four's Johnny Storm. This version of the character was essentially a synthetic android who fought alongside Captain America and the Invaders in World War II.

Although the character doesn't get a starring role in Captain America: The First Avenger, we do catch a glimpse of him during the World of Tomorrow expo scene. For all we know, the android was later dispatched during the war to help in the Allies' battle, and he brought all of his fiery power to help.

10 SLEEPER MECHS

Ultron bots aren't the only robotic lifeforms that Hydra was working on. In Agents of S.H.I.E.L.D.'s fifth season, a new form of remote-controlled robots were introduced in the form of the Shock Troopers. These robotic soldiers were originally failed attempts to re-create the LMDs, re-programmed into being General Hale's personal agents.

The Sleeper Mecks proved to be quite dangerous when they engaged in battle with Agent Coulson and the rest of his team. What's more, they were even harder to put down. Stopping some of these Troopers required the intervention of powerful enhanced individuals, like Daisy Johnson's Quake or the Absorbing Man.

9 J.A.R.V.I.S.

Tony Stark's main operating system, J.A.R.V.I.S., was a powerful entity even before he was re-programmed into the Vision. Although he started out as the system behind the Iron Man suit, he quickly evolved into an instrumental part of Tony Stark's operation, to the point that J.A.R.V.I.S. was just as heroic as the man himself.

J.A.R.V.I.S. received a starring role in the final battle of Iron Man 3, where he essentially led the charge as the artificial intelligence behind Stark's House Party Protocol. Dozens of Iron Man suits took the fight to Aldrich Killian and his Extremis-enhanced soldiers. J.A.R.V.I.S. showed great power in controlling this army, once again proving how vital he is to the MCU.

8 ULTRON BOTS

When Baron von Strucker and his Hydra forces came into possession of the Mind Stone, they already had an idea that this gem's power could lead to artificial intelligence. For that reason, they started creating robot sentries in the hopes of instilling an artificial system inside of them. However, that system would only come later, in the form of Ultron, who found the ability to control all of these robots.

The Ultron bots proved dangerous. With propulsion units and blasters, their large numbers helped them prove to be a true force to be reckoned with against the Avengers. On top of that, their connection made it so that Ultron could hop in and out of any one of them, all while they operated under his command.

7 LMDS

In Agents of S.H.I.E.L.D.'s fourth season, the Marvel series dove head-first into the mythology of the life-model decoy robots, or LMDs for short. These robots proved troublesome because they are made to look exactly like humans, something that made them very difficult to point out in the middle of a crowd.

In fact, no one had any idea that Melinda May had been replaced by an LMD for a long period of time. Eventually, almost all of the main character from the series had been taken out and replaced by LMDs, one by one, to the point that Phil Coulson's team was almost defeated by the robots.

6 ARNIM ZOLA

In the Marvel comic books, Arnim Zola's life was prolonged thanks to his mind being transferred into the body of a robot, making him a Captain America villain for a very long time. In the Marvel Cinematic Universe, Arnim Zola's life was also prolonged, his mind kept alive by an entire warehouse of servers, processors and mainframes.

The villain was revealed to be alive in Captain America: The Winter Soldier, where Zola's face appeared through a screen. He may not have had a body to move around in, but he was still so smart and dangerous that he was able to help shape worldwide events alongside Hydra, as well as develop an algorithm to take out potential targets all over the world.

5 THE SUPERIOR

Anton Ivanov first appeared as a human villain on Marvel's Agents of S.H.I.E.L.D. He was the leader of the Watchdogs, and sought to get revenge on Coulson and his friends. His drive proved strong, and his passion for power eventually led to him seeking to become something else entirely.

With the help of the sentient LMD Aida, Anton Ivanov became the Superior, a powerful android who could control many other of his robotic doubles, to the point that it was difficult to deduce which was the “prime” version of the Superior. Over the course of two seasons, Ivanov was one of the main enemies of the series, and a powerful one at that – one almost impossible to put down.

4 AIDA

Aida was perhaps one of the most dangerous villains the Agents of S.H.I.E.L.D. team ever faced. She was originally the first new life model decoy, and originally designed to help Coulson and the rest of his team. However, Aida eventually became corrupted by the Darkhold. Once she gained sentience, she came to have devious plans of her own.

Not only was she able to replace most of the Agents of S.H.I.E.L.D. team with LMD versions of themselves, she also plunged them into an alternate reality created by a computer program that placed Hydra as the governing force of the world. As for Aida? She was the self-proclaimed Madame Hydra, complete with green hair highlights.

3 ULTRON

Ultron was created by Tony Stark, Bruce Banner and the Mind Stone. Although it was intended for him to be a force for good, Ultron quickly realized that humanity was a burden on the planet and that they needed to be exterminated. With infinite access to the Internet and countless Ultron bots, Ultron took the fight global.

Armed with vibranium, Ultron created a meteor that would wipe out all life from the face of the Earth. With his own vibranium body, the robot had great power which allowed him to go toe-to-toe with Iron Man, Thor and the Vision. While he didn't end up completing his goal, he did manage to kill an Avenger.

2 THE DESTROYER

Not all of the Marvel Cinematic Universe robots are created on Earth. In fact, some of them are actually powered by magic – Asgardian magic at that. The Destroyer is one of Asgard's biggest weapons, a remote-controlled giant who can wipe out anything that stands in its path.

Not only does it have a raw strength that can't be compared, it can mow down Frost Giants and any other living creature with its powerful beam. The Warriors Three could barely make a dent in the Destroyer's armor, and it would take all the mighty power of the God of Thunder to destroy it.

1 VISION

Vision is a creation of the Avengers. He was made from Vibranium, he was programmed with J.A.R.V.I.S., and he was brought to life with the lightning of Thor. But all of this doesn't compare to the power of the Mind Stone in his forehead. With it, Vision is easily the most powerful member of the Avengers.

In fact, his power can't be compared. He can phase through walls and objects, he can shoot a powerful laser beam from his forehead and he has strength that can barely be matched. He was the one who defeated Ultron, and rarely is he allowed to cut loose. Truth be told, we have no idea of the limits his power has – if there are any. It's simple really: Vision wins.
