For as long as there have been superheroes there have been boys who run around with their arms outstretched pretending to fly and have super powers. Superheroes are big, not only in popularity but in the larger-han-life personas. Kids love the heroic fantasy, the myth, the idea of being a superpowered macho man who can right wrongs, battle bad guys and save innocent people with ease.
Right now, some of the most popular boy's Marvel Comics Halloween costumes are Thor, Iron Man and the X-Men. Really, if you're ever unsure, all you need to do is look at what the most recent superhero film releases are. That said, the kid you're buying the costume for probably has a personal favorite superhero, and chances are, you knew who it was before you started reading this article.
The artists at Marvel have a longstanding tradition of designing iconic characters with brilliant, memorable costumes. The simple primary and secondary color schemes, iconic designs and general coolness all make up a formula that boys of all ages love and will always love.
By the time you read this, there's a good chance that Captain America and the new Ghost Rider films will have been released. In other words, if your kid is a fan of these characters, grab the costumes for them now while you can, because chances are they're going to be sold out by the time the next Halloween rolls around.
