Top 10 Dumbest Mistakes In The MCU

“Guardians of the Galaxy” (2014)

While a few Guardians are trying to offload the Orb that contains the Power stone to the Collector, a drunken Drax is left alone for a little too long. He finds a communication hub and decides to challenge the villainous Ronan the Accuser to a fight. Was calling out the highly trained Kree warlord who killed your family and wanted the power stone a bad idea? Definitely. After the whole group's exact location is revealed, Ronan and a few members of his army arrive to cause trouble. While the accuser beats Drax to a pulp, his subordinate Nebula grabs the orb. Even the notoriously reckless Rocket calls his future teammate out for messing up their mission this badly.

“Spider-Man: Far From Home” (2019)

Peter Parker was already feeling weighed down by the responsibilities that come with being Spider-Man. He only feels more pressure after he inherits E.D.I.T.H. from Tony Stark and almost slays a classmate with a drone connected to the high-tech glasses. So, Peter decides to give them to one of the many responsible adults he worked with to save the universe. Just kidding. He hands them off to Quentin Beck, a superhero stranger he just met. This doesn’t turn out well. Beck uses E.D.I.T.H. to cause destruction so he can appear to be the world’s greatest superhero. Honestly, this could’ve been avoided if Peter made a longer list of options of who should get access to killer drones.

“Hawkeye” (2021)

If you sneak into a black market auction and find a suit that belonged to a vigilante named Ronin, should you put it on? That’s the question Kate answered when the Tracksuit Mafia attacked an auction. Her decision to put on the Ronin costume and take out enemies actually could’ve worked out alright for Kate Bishop. However, she didn’t ditch the suit right away. Instead, she keeps it on while she stops by her apartment. This allows the tracksuit mafia to trace Kate right back to her doorstep. And to make matters worse, they’re easily able to figure out her identity. Kate might’ve been able to stay ahead of the tracksuit mafia if she had just made a costume change sooner.

“Thor: Ragnarok” (2017)

Loki isn’t exactly known for his good judgment. In “Thor: The Dark World”, he tried to get the villain Algrim to make Thor suffer. But Loki’s actions led to the death of his mother instead. He made an even worse judgment call when his Asgardian sister Hela arrived on Earth. When Loki became intimidated by her power, he called on the Bifröst Bridge to escape. Unfortunately, his vicious sis followed them for the rainbow ride while sending him and Thor to the gladiator prison planet Sakaar. Hela used her ability to draw power from Asgard to slay warriors and conquer the kingdom. The only way to stop her was to destroy Asgard completely. A split second decision cost Loki and many others their home.

“Avengers: Infinity War” (2018)

A team that includes Spider-Man, Dr. Strange, Iron Man, Drax, Mantis and Star-Lord should be able to pull off some tremendous feats. At the very least, they should be able to get one glove off a universe-threatening alien, right? Unfortunately, Peter Quill doesn’t always think about the big picture. Iron Man and Spider-Man were extremely close to removing the Infinity gauntlet from the mad titan when the emotional Guardians leader decided to ask the villain about Gamora. Once Quill learned that Thanos slayed her, he hit the big bad in the face and disrupted the team’s plan. The titan took advantage and was able to get his hands on the Time Stone. In the future, Quill will hopefully wait until a plan is finished before questioning a villain.

“Avengers: Age of Ultron” (2015)

When given access to the mind stone, Tony Stark convinces Bruce Banner to help him build a new way to protect the Earth. Together, they create an AI program named Ultron. But the humans decide to leave it alone with a computer system named J.A.R.V.I.S so they can party. When Ultron wakes up, it takes out its fellow AI immediately. Shortly after this event, the villain decides that protecting Earth means devastating the earth’s population. You'd think a couple of nerdy scientists who quote sci-fi movies would’ve watched movies with evil AI’s and decided against Ultron. But they ignored the obvious warning signs and created a villain who nearly caused an extinction event.

“Guardians of the Galaxy Vol. 2” (2017)

Peter Quill was feeling pretty special about his relationship with his long lost father Ego. The Guardian could even access great celestial powers while hanging on his dad’s planet. For a moment, it looked like Quill would take over the universe with his dear old pop. However, Ego throws a wrench into the plan when takes his villainous monologue a step too far. The villain admits that he gave Quill’s mother Meredith cancer because she was too distracting. This revelation instantly breaks any loyalty Peter felt for his murderous father. If the villain’s “ego” hadn’t been so big, this celestial being might have achieved his goal of universal domination. Instead, the Guardians of the Galaxy destroyed his planet-sized brain with a Groot-placed bomb.

“Iron Man 3” (2013)

From the moment he declared he was Iron Man at a press conference, Tony Stark’s proven he doesn’t feel the need to hide who he is. But he once took his comfort with the public a little too far. After his friend Happy is hurt while investigating the Mandarin, Tony gives up his address and challenges the villain to confront him on live TV. But he soon learns that some information should be kept secret. By the time Tony realizes his mistake, his house is destroyed and he nearly loses his girlfriend Pepper. What makes this whole debacle worse is that the Mandarin isn’t Tony’s only enemy. If that villain didn’t attack, surely some other criminal would have shown up to do the job.

“Spider-Man: No Way Home” (2021)

After Peter’s framed and unmasked by Mysterio, he and his loved ones suffer. He and his two best friends seemingly can’t get into any of the universities they applied to. Instead of calling admissions, Peter Parker tries to fix everything with magic. Although Dr. Strange has a memory spell that can fix things, Peter fails to go over the details until the casting begins. The teenage hero soon distracts the sorcerer with questions and causes a major spell malfunction. Peter’s actions lead to multiversal villains attacking, the death of his aunt and more. He ultimately has to erase himself from everyone’s memories to set things right. In the end, today’s lesson is to communicate with college admissions departments before asking for world altering spells.

“Avengers: Infinity War” (2018)

During a pivotal battle in Wakanda, Thor’s battle ax flies through the air and lands in Thanos’ chest. The Asgardian then takes a beat to savor his achievement and uses Stormbreaker to cause more suffering. However, he could’ve easily taken out the hand with the gauntlet full of Infinity Stones while enjoying his triumph. Thor could’ve also taken a moment to cut off the titan’s big purple head. Unfortunately for the Asgardian, Thanos is still able to complete the Snap with an ax in his chest. Thor’s failure to follow through immediately resulted in the disintegration of half of the population of the universe. It just goes to show that you should always choose the head over the heart.
