    Taserface

    Description of 'Taserface' in the list 'The Dumbest Characters In The Marvel Cinematic Universe, Ranked' TaserfaceTaserface joined the Ravagers and led a mutiny against Yondu for command of the faction. He acts gruff and arrogant; he clearly lacks the smarts needed to lead his people.

    Why Is He So Dumb? Unknown.When Taserface captured Yondu, he eliminated nearly everyone loyal to him but kept his former captain alive. Taserface then left Groot alive, a major mistake given his status in the Guardians of the Galaxy.

    His Dumbest Moment:Taserface knew Yondu was dangerous with the Yaka Arrow. He left the arrow untouched instead of snapping it. This action let Yondu escape, grab the fin and arrow, kill everyone loyal to Taserface, and destroy the ship. Taserface named himself Taserface, thinking it would scare enemies, but it just made them laugh at him.

    His Dumbest Line:"It's too adorable to kill!"

    Trevor Slattery / "Mandarin"

    Trevor Slattery / "Mandarin" TrevorTrevor played "The Mandarin" for A.I.M. This villainous revolutionary leader scared Americans. When it became clear he was just the "face" of the group, not a real leader, he was a clumsy idiot.

    Why Is He So Dumb?Trevor took a job that made him a villain. He caused many attacks even without carrying them out. Trevor showed terrible judgment and poor impulse control.

    His Dumbest Moment:Once his true nature showed, everything Trevor said and did proved how foolish he is. Taking the Mandarin job was his dumbest moment. His talk with Stark did nothing to improve anyone's view of his intelligence.

    Roger Harrington

    Roger Harrington Mr. HarringtonMr. Harrington teaches science at Midtown School of Science and Technology. He supervises the school's academic decathlon team and teaches Peter Parker.

    Why Is He So Dumb?Though Mr. Harrington earned his degree from Culver University, he ignores everything around him. This makes him a poor choice to manage children in Washington, DC, and Europe.

    His Dumbest Moment:Chaperoning the Europe trip showed Mr. Harrington's foolishness. He dropped his camera in a Venetian canal. He did not research the trip beforehand. He took his kids to a closed museum. He accepted all the unexpected upgrades without questioning them, even though the situation seemed strange and possibly a trap.

    His Dumbest Line:"As you know, we made it out alive. And that's the important thing. I couldn't bear to lose a student on a school trip. Not again."

    Drax The Destroyer

    Drax the Destroyer Drax the DestroyerDrax the Destroyer was locked up with other future Guardians of the Galaxy members for an unknown crime. He vowed revenge on Ronan the Accuser for destroying his family. Drax possesses immense strength and boldness. This often leads him to act recklessly, yet he proves useful later.

    Why Is He So Dumb? He seems unintelligent because his species fails to grasp English subtleties like sarcasm and metaphors. This is a joke, not stupidity. His real lack of smarts shows up in nearly every situation. Drax does not think; he rushes in to hack, slash, and slug.His Dumbest Moment: Calling Ronan to Knowhere when no one was ready for his arrival. This left Drax barely alive, and almost killed Gamora. The Ravagers captured Gamora and Quill.

    His Dumbest Line: "The beast's hide is too thick to be pierced from the outside. I must cut through it from the inside."Drax called Ronan to Knowhere. Nobody prepared for his arrival. Drax held onto his life by a thread. Drax almost ended Gamora. The Ravagers captured Gamora and Quill.

    Why Is She So Dumb? Her confidence edged into arrogance. This made her open to bad choices in high-pressure moments.Dumbest LineHer Dumbest Line: "Sorry, the 'prisoners with jobs' have armed themselves."Who He Is: Alexei Shostakov, formerly and sometimes currently the Red Guardian. He was a father figure to Natasha Romanoff and Yelena Belova, but only because the Red Room assigned him that role. A former Soviet Union hero, the Red Guardian is obsessed with his past glory and being better than Captain America.

    Who She Is: TopazTopaz served as the bodyguard and right-hand woman to the Grandmaster. She enjoyed hurting people and barking at anyone she disliked. Topaz remained polite and sophisticated toward her boss, showing complete loyalty.

    The Other

    Who He Is: The OtherThe Other acted as Thanos's vocal proxy and second-in-command. He represented the Mad Titan in his dealings with his subordinates and served as his personal servant. He gave Loki the Chitauri Army to conquer Earth and gave him the scepter, which held the Mind Stone.

    Why Is He So Dumb?The Other assumed he was as powerful as his master when he spoke for him. This proved to be his downfall.

    His Dumbest Moment:While speaking to Ronan the Accuser, The Other spoke down to him, treating him like nothing. Ronan did not tolerate disrespect. Ronan raised his voice to the Kree zealot, and Ronan swiftly snapped his neck with his Cosmi-Rod.

    His Dumbest Line:"Lower your tone! I may be your..."

    Red Guardian

    Who He Is: Alexei Shostakov, formerly and sometimes currently known as the Red Guardian, was a father figure to Natasha Romanoff and Yelena Belova. The Red Room assigned him this role. A former Soviet Union hero, the Red Guardian is obsessed with his past glory and being better than Captain America.

    Why Is He So Dumb?:Pretending to be a sitcom dad rubbed off on him. Two decades in a top-secret prison probably did not help. Shostakov shows paternal ignorance; he is embarrassingly uninformed and unaware of it.

    His Dumbest Moment:After twenty years in prison, Red Guardian responds to a package with cautious hope. Then, he watches cruel guards eat the items his fans sent, seeming like the same trick for the thousandth time. Red Guardian acts like Charlie Brown with the football, falling for the same trick and never learning why.

    His Dumbest Line:“Still fits.”

    Jimmy Woo

    Who He Is: Jimmy WooIs an FBI agent and former S.H.I.E.L.D. agent. He oversaw Scott Lang's home detention as Ant-Man. Jimmy Woo is friendly and amiable, but he lets his good nature hinder his job.

    Why Is He So Dumb?He thought he could outsmart Scott Lang, Hope van Dyne, and Hank Pym, three of the smartest people in the MCU. He also struggles to talk to kids. When he explained Lang's house arrest to Cassie, Lang's daughter, he failed to get his point across.

    His Dumbest Moment:He failed his job by letting Lang and others trick him. Though this helped the greater good, it did not look good on his annual review.

    His Dumbest Line:“Seriously? Yes! Oh. Sorry, Scott. They were your friends. That's insensitive. I just needed a win, you know? Anyway, I'll be back later for the official end of your sentence. Sorry for misjudging you, pal. You should feel great about yourself.”

    Skurge

    Who He Is: SkurgeThe Executioner managed the Bifrost Bridge after Loki took control of Asgard under Odin's guise. While there, he gained wealth from various realms. He used this position to impress women, but it failed. When Hela, the Goddess of Death, appeared, he dropped his principles, joined her, and became her executioner. Later, he turned against her and even sacrificed himself to save the Asgardians.

    Why Is He So Dumb?Skurge acts more like a warrior or mercenary than a thinker. Skurge emphasizes looking and acting tough like any Asgardian warrior, but he lacks the brains to support his strength.

    His Dumbest Moment:As with the rest of Asgard, he believed Odin, but Loki tricked him too. Despite believing Odin, he did not get rattled when he found out Odin was Loki. Later, joining Hela was just to save his life. This might have been smart then, but it brought him huge guilt.

    His Dumbest Line:Well, look who showed up. Thanks for scaring away my company and soaking my workplace in brains.

    Ronan The Accuser

    Why Is He So Dumb?:Ronan is powerful. He is not stronger than Thanos or others like him. This does not make him dumb. He made an idiotic choice to fight the Mad Titan, the full might of Xandar, the Ravagers, and the Guardians of the Galaxy.

    His Dumbest Moment:Ronan opposed Thanos. He held the Power Stone then, but that was reckless. His dumbest moment happened when he stopped destroying Xandar after Star-Lord's dance-off distracted him. He stopped to ask what Star-Lord was doing. That proved his failure.

    His Dumbest Line:"YOU CALL ME 'BOY?!' I will unfurl one thousand years of Kree justice on Xandar AND BURN IT TO ITS CORE!! Then, Thanos, I'm coming for you!"

    Luis, Dave, & Kurt

    Who They Are: Luis, Dave, and Kurt are reformed criminals. They still get into dirty work when they help their buddy, Scott Lang. They lack the highest intellect in the Marvel Universe. They mean well. When things get tough, they do the right thing, making them good guys.

    Why Are They So Dumb?They focus on the end result. They spend little time preparing. This makes them act blindly often. Even when they follow a plan, they mess things up. This causes problems for everyone involved. They escape trouble just as fast as they get into it.

    Their Dumbest Moment:Their collective dumbest moment was also one of the most important for the MCU. They hatched a plan to take something, which turned out to be Hank Pym's Ant-Man suit. Scott worked out well, and they later became security experts with their own company. This plan was stupid from start to finish; Lang's inclusion made it work.

    Luis' Dumbest Line:"Yeah, my mom died, too. And my dad got deported. But I got the van!"

    Dave's Dumbest Line:"We broke into this spooky ass house, didn't we?"

    Kurt's Dumbest Line:"Old man have safe."

    Why Is He So Dumb?Korg fights for freedom. He struggles to organize, relying instead on his strength and toughness to win fights. Korg has good aims and acts friendly, but he lacks the intelligence of other MCU characters.

    Korg's Dumbest Moment:This happened off-screen.KorgKorg tried to organize a revolution but failed to print enough pamphlets. This resulted in his capture. Then, Korg entered the Contest of Champions to fight as a gladiator. Many people online call this a hilarious example of "paper beating rock."Korg offers a hilarious example.This involves "paper beating rock."

    Korg's Dumbest Line:"I tried to start a revolution but didn't print enough pamphlets so hardly anyone turned up. Except for my mum and her boyfriend, who I hate. As punishment, I was forced to be in here and become a gladiator."

    Star-Lord

    Who He Is:Peter Quill was taken from Earth at age 8. This happened after his mother died. The Ravagers who took him made him one of their own. He is a superhero, an outlaw, and the leader of the Guardians of the Galaxy.

    Korg is so dumb because...Peter is sensitive and caring. He is not the smartest person. He only received education through the third grade, which was not his fault. He grew into a capable adult, even if his feelings sometimes block smart choices.

    Korg's Dumbest Moment:He found the Power Stone. He showed it to everyone without knowing its importance. This led to his detention. The events created the Guardians of the Galaxy, which worked out. But Peter should have thought ahead instead of just reacting to everything.Avengers: Infinity WarPeter compromised the plan to take the Infinity Gauntlet from Thanos. The plan almost succeeded. Quill became so upset about what happened to Gamora that he ruined everything.Korg blew the whole thing..

    Korg's Dumbest Line:"I don't learn. It's one of my issues."

    Mantis

    Who She Is: MantisMantis is an empathic alien raised by Ego. When she first met the Guardians of the Galaxy, she knew nothing about other people, customs, or behaviors. She did not fit in well. Her bond with Drax made her decide to warn the Guardians and challenge her master. Later, she joined the Guardians of the Galaxy and fought Thanos inAvengers: Infinity WarandEndgame.

    Mantis is so dumb because...Her stupidity stems mostly from her lack of knowledge about the universe and the people in it. This makes her say and do things that seem unintelligent. Mostly, she is innocent, only now understanding the universe's nature.

    Mantis's Dumbest Moment:Her dumbest moment came inAvengers: Infinity WarMantis mentioned Thanos felt great sadness while she tried to stop him. This revealed he was grieving Gamora. Keeping quiet about Thanos's feelings would have let the team take the Infinity Gauntlet and stop the Snap/Blip.

    Mantis's Dumbest Line:"Listen! Ego's gotten exactly what he wanted. I should have told you earlier. I'm stupid. You are in danger."

    Baby Groot

    Who He Is:BabyGrootis the Groot who appeared at the end of the first film.Guardians of the Galaxyfilm as a sapling. He is the same species, just younger. He stays with the Guardians of the Galaxy and proves he is as deadly as his former self.

    Why Is He So Dumb?Baby Groot is not the same Groot from the first film. He acts like his offspring. He lacks smarts compared to his adult form because he is young and doesn't know the world.

    His Dumbest Moment:Baby Groot had several silly moments inGuardians of the Galaxy Vol. 2, and while they were cute and funny, he showed little world knowledge. One time, he failed to bring Yondu the fin after knowing what to look for. He brought a desk, a toe, and nearly everything else, but not the fin. Later, Rocket told him not to push a bomb button, but he misunderstood the orders and ran off with the bomb.

    His Dumbest Line:"I am Groot?"

    Darcy Lewis

    Who She Is: Darcy LewisDarcy Lewis studied political science at Culver University. That program made her Erik Selvig and Jane Foster's assistant, yet she knew little about their work. She was a bad fit for a lab assistant and should not have worked with them, but her education led her there.

    Why Is She So Dumb?She lacks understanding of science, quantum mechanics, or anything she does for Selvig and Foster.

    Her Dumbest Moment:She applied for a lab assistant job while studying political science. Six credit hours might have been fine, but it made no sense.

    Her Dumbest Line:"I am not dying for six college credits!"

    Thor

    Who He Is: Thor Odinsonis the Asgardian God of Thunder. He is Loki's adoptive brother and Odin's son. He was supposed to rule when his father stepped down, but his arrogance and refusal to follow Odin's orders showed he was unfit. Odin took his hammer and powers, banished him to Midgard. Later, he joined the Avengers, hunted Infinity Stones, killed Thanos, and acquired the mother of all 'dad bods.'

    Why Is He So Dumb?Thor is not unintelligent, but he makes very stupid choices. After living over 1,500 years, he does not learn from his mistakes fast. He needs many failures before he finally thinks about his life and his choices.

    Thor's Dumbest Moment:Thor defied Odin and attacked the Frost Giants on their home world. This angered their king. It revealed the truth about Loki's beginnings. It caused his banishment. It made him unworthy of Mjolnir and his powers.

    HisDumbest Line:"He's a friend from work!"

    Thanos

    Who He Is: Thanos, the Mad Titan, believes only wiping out half of life saves the universe. To do this, he hunts and gets all the Infinity Stones. He snaps his fingers with the Infinity Gauntlet, making his dream real.

    Why Is He So Dumb?Thanos is not unintelligent, dumb, or stupid. He might be the smartest character in the MCU. Still, he makes incredibly stupid decisions.

    His Dumbest Moment:Thanos's plan to end half of all life for safety was poorly thought out. Wiping out half of the plants, animals, and people would cause chaos, more deaths, and broken governments. It would also cut off food supplies, leaving most people starving. His goal did the opposite. He also kept underestimating his enemies, especially at the end ofAvengers: EndgameWhen he attacked the combined MCU force, he underestimated Tony Stark. This proved his dumbest move. It resulted in the complete removal of Thanos and all his people.

    HisDumbest Line:"You should have gone for the head."

    Captain America

    Who He Is:Steve Rogers became weak before the experiment. That experiment used a special Super Soldier Serum to turn him into Captain America. He fought HYDRA and the Germans in WWII. Ice froze him for seventy years. He woke up now. He led the Avengers against many threats and proved he was a good tactician.

    Why Is He So Dumb?Cap is not dumb. He does not always use his smarts for good choices. When he lets his feelings guide what he thinks is right, he often takes a hard path. This made his time now very hard.

    His Dumbest Moment:Cap always cared for Bucky. But as the Winter Soldier, Cap sacrificed himself to save his friend. While noble, it was not a smart move. He chose Bucky over Tony and even his country during theSokovia Accordsdivided the team inCaptain America: Civil WarCaptain America fought Tony with Bucky. This fight destroyed the Avengers. Thinking clearly, he should have worked with his friend, not fought him.

    His Dumbest Line:""English"
