Marvel Costumes for All Ages [Costume Guide]

Superhero costumes have long been a popular theme for Halloween dress-up. Though Spider-Man has always been on top, options have only increased thanks to the Marvel Cinematic Universe. And while capes, spandex, and masks have mostly been a kids' game, there are tons of Marvel costumes for adults who want to dress up as their favorite characters from the latest superhero blockbusters. If this sounds like a fun time, then we're sure you'll enjoy this guide to our favorite Marvel costumes for all ages!

It’s time, once again, for the Avengers, X-Men, and others to assemble. If you’ve been following the Marvel Cinematic Universe over the past decade, you know that big things are on the horizon for Earth’s mightiest heroes. The Avengers movies have been a favorite of many superhero movie enthusiasts, and it's not hard to see why! Avengers movies like this might feature up to 76 characters, which could make for one epic group Halloween costume. Check out our list of superhero costumes for kids and adults and figure out how you’re going to assemble your team of Earth's mightiest heroes.

Iron Man Costumes

Tony Stark has some of the coolest tech in the Marvel universe, which shouldn’t come as a surprise because he’s a billionaire. Dressing in Iron Man costumes for Halloween doesn’t mean wearing real metal Iron Man suits, of course. Do you know how heavy that would be? There are Iron Man suits for men and women—though that would just be an Iron Woman costume, right?—made from fabric or molded plastic. If you're looking for a true metal superhero outfit, you may have to forge your own.

Captain America Costumes

Another character leading the charge among the Avengers is Captain America. Steve Rogers has become one of the most popular Avengers, especially after being proven worthy enough to wield Mjolnir. And there’s no denying his strength and leadership were needed in the fight to save the world from the mad titan Thanos. Slip on one of these Captain America costumes and you too can lead the charge in your favorite superhero costume.

Spider-Man Costumes

Do you wish you could do whatever a spider can? Find the perfect Spider-Man suit that will help you climb walls, leap from buildings and shoot webs...okay, maybe you won’t have those powers, but you’ll still look like a friendly neighborhood Spider-Man. This, however, is a good thing because with great power comes great responsibility. Since you don’t have the powers, why would you have to worry about the responsibility? (Spider-Man costumes are popular superhero costumes for kids, so maybe don't tell them the responsibility bit.)

Black Widow Costumes

Black Widow might be the toughest Avenger of them all. She doesn’t have a high-tech suit or a shield made out of advanced metal to protect herself, yet she manages to do some damage when it comes time to fight. It certainly doesn't matter what kind of trouble she finds herself in. She's resourceful enough to take care of herself and even puts up with the cumbersome task of keeping heroes like Iron Man, Captain America, and even the Hulk in check. You'll feel ready to take on any costume party with these Black Widow costumes!

Thor Costumes

Thor, son of Odin and god of thunder, is a force to be reckoned with as one of the strongest Avengers. (Although you might not want to enter that debate.) While Thor may have undergone a physical transformation in losing his long hair in the movies, anyone who knows the character knows that he’s most recognizable with his long hair. If you’re not in a big costume group, you can pair Thor costumes with Hulk or Loki!

Incredible Hulk Costumes

Incredible Hulk costumes are a smash! If you’re feeling angry (or are always angry), express some pent-up rage dressed up as Bruce Banner in full Hulk mode. The superhero costume idea speaks for itself, and you can choose whether you want to go with a mask, a simple wig, or full-on green makeup. If you're looking for a fun couples costume idea, there are some options with Hulk. You can dress up as Tony Stark, his scientific counterpart in the MCU, Black Widow, his love interest, or his buddy Thor from their team-up in Thor: Ragnarok.

Black Panther Costumes

All hail the king! After making waves at the box office, Black Panther has quickly become one of the more popular Marvel superheroes in the entire MCU. Next to the Iron Man armor, Black Panther’s suit is one of the best superhero costumes in movies. That's because it's virtually indestructible and can turn the energy it takes into a counter-attack. Much like his home country of Wakanda, the Black Panther is one of the more stealthy superheroes, so it should also come as no surprise that his entire suit can be carried around in a necklace and forms around his body when he needs to leap into action. With these Black Panther costumes, you still achieve the stealth look of T'Challa's superhero suit, but you'll need to put them on the old-fashioned way.

Guardians of the Galaxy Costumes

If you’re looking to assemble a team of misfits, Guardians of the Galaxy costumes are probably more your style. Whether you’re looking to dress as a cunning leader like Star-Lord, a skilled fighter like Gamora, or a trash-talking raccoon like Rocket—or Guardians of the Galaxy group costumes with all of them—these Marvel costumes will put the fun in dysfunctional. Dressing up as the Guardians of the Galaxy is a great idea, but your group costume is going to need a few things: a sweet ride to cruise the galaxy with, an awesome mix filled with killer tracks, and a Groot.

Avengers Costumes

Of course, there are many more superheroes in the Avengers. One might argue there are too many—though they'd be wrong. But if you’re looking to assemble the biggest group of heroes, you’re going to need some Avengers costumes. You can’t count out marvelous superheroes like Doctor Strange, Ant-Man, or Captain Marvel herself. And you can't forget Hawkeye, either, although previous promotions for the Avengers have.

X-Men Costumes

Before the MCU and the Avengers, there were the X-Men! If you grew up on the 1992-1997 animated series and the film series starting in 2000, they're probably who you'd consider to be classic Marvel characters. We're talking about fan favorites like Wolverine, Rogue, Jean Grey, and Deadpool. (Yes, Deadpool was totally in the X-Men and he had the trainee jersey to prove it!) We couldn't forget about them, either, which is why we've got a great selection of X-Men costumes for you to choose from!

So which of these Marvel costumes will you be wearing to save the world—or, you know, win the annual Halloween costume contest? Everyone has their own favorite superhero suit, but there's just something super cool about seeing so many heroes coming together. If you want to dress up for the premiere of the latest superhero team-up film or solo adventure, round up your pals and check out all of these superhero costumes to put together your own unique team.
