In the comics, and in the movies, most superheroes are loaded. Batman is positively swimming in buckets of cash. Iron Man oozes dollar bills out of his pores. Arrow is loaded. Even the superheroes who aren't bazillionares, like Flash, and Superman, aren't hurting for cash. You just generally don't see your garden-variety superhero on the corner, cardboard sign in hand.
Superheroes need cash to do their jobs. Those fancy costumes and tools cost an arm and a leg. The Batman not only has to shell out money for special outfits, he also has to maintain the Bat Cave, Batmobile, Bat Plane, Bat Boat, and whatever other patented Bat vehicle he creates. Those high tech specially designed suits that Iron Man wears are not found on close out at the local Walmart. Superman not only has to keep himself in spandex, he also has to keep himself in those fake glasses he wears to fool Lois Lane. Even the Flash has to keep himself fed, since his super fast metabolism means that he has to eat more than the entire offensive line of the last Super Bowl winner.
Not all of us have trillions of dollars lying about in a vault, which is really a shame. That doesn't mean that superhero-dom is not for you, however. Maybe you won't have all the cool toys, but since most people have no idea what to do with a batarang, anyway, that's probably a good thing. Anyone can be a superhero, no matter the income. There's a few decisions that need to be made first.
1. Cape or No Cape? One cannot deny that Superman looks pretty awesome in a cape. And Batman would not be so very mysterious and 'bat-like' without a cape. A cape can make a person feel...super. If that piece of material is all that stands between you and your new career as a superhero, then go for it. However, after viewing the movie The Incredibles, my feelings on capes underwent an adjustment. And there are a number of successful superheroes who do not have capes. A cape would slow the Flash down, for example. So capes are really a personal decision.
2. Practice Your Stance Every superhero has a stance. It's expected. It may be a law of the Universe or something. Superman has that hands-on-hips, legs wide apart, cape flowing in the breeze. It's that stance that conveys to the world, "I am mighty!" A number of other superheroes have adopted a similar stance, but that's certainly no reason not to come up with your own unique way of letting the world know that you...are mighty.
3. Theme Music Every time Captain America shows up on the screen, there is soaring music to let you know that he is there to save the day. Batman usually has some dark score soaring in the background to let you know that he's there, even if he is in one of his secretive moods. Theme music sets the stage for the hero, and if there's a song that makes a person feel heroic and superhero-ish, then that should be their theme song. Eye of the Tiger seems to be a favorite, but really, any song will do. No one has to hear it but you, through your headphones or in your head, if you don't want anyone to know. If it makes you feel super, it's worthy.
4. Sidekicks Are Essential Batman has Alfred, and Robin. Superman has his mom, and a few other insiders. Iron Man has Pepper Potts, and War Machine. Captain America has the Falcon, and Bucky Barnes. The Flash has a team of scientists and police officers on his side. Half of Star City apparently knows that Oliver Queen is the Arrow, but they are all essential to his do-gooder team. Every superhero needs a helper, and that's a fact. Heck, just getting into those spandex outfits must take at least two people! And some good deeds require more than one person to complete them. Soup kitchens, for example, couldn't exist if only one person was running them.
5. Do Some Good Deeds This is the most essential part of being a superhero. Batman's life is dedicated to taking back Gotham City from criminals. Superman is all about truth, justice, and such. The Flash rushes in to help as many as he can. Superheroes come in all shapes and sizes, but the one thing that they all have in common is the desire to help others in some way. You don't have to be a superhero for that, you just have to want to help. It doesn't require super strength to volunteer to read to senior citizens. Helping out at the local animal shelter doesn't require a special spandex suit. It just requires YOU. Giving your time to worthy causes doesn't require any extra equipment or cash, but it will sure help you feel like a superhero.
You can even wear a cape and have your sidekick follow you around with your iPod speakers blaring your theme song.
