There are a lot of things that go into creating a super powered being, and all of them can be boiled down to two words: back story. You have to decide what power they have, how they got it, when it showed up, and a million other things before actually writing out the good parts. However, developing the super hero (or villain) is a bit more complicated.
The first thing to do with the development of a super is to teach them how to use their power. This can be a lot of fun because it gives you the chance to have your character make a lot of mistakes. The character is brand new to this and has no idea what the limits to this power are, or even if there are limits. So this is your chance to have them turn invisible in the middle of a first date, tear their car door off, or burn down the model airplane they’ve been working on forever. Teaching your character how to use their power can also help develop the super as a character. It helps to show how they handle different situations, or how they think about the world and the people in it.
The important thing to remember about super heroes and villains is that deep down they’re still human. They have the same wants, needs and motives as anyone else: love, greed, sympathy, anger, etc. However, what makes them interesting is the fact that they have power. They have abilities that no one else has, and that’s where writing these characters gets really interesting. Once the character has these powers (and knows how to use them) the logical next step is to make the “big decision.” Are they a hero or a villain. In comic books the decision to be a hero or a villain is almost always made after a major life event. This can be the death of a loved one, being framed for a crime, sometimes even after the character’s own death. What the writer has to think about is how the character deals with the particular event. This is just like any character development, but with the addition of powers. This may not seem like a huge addition, but it is, and this is because it gives a lot of possibilities for a reaction scene.
After any huge life event a person is going to feel a very strong emotion or maybe a bundle of emotions they can’t easily untangle. The trick to this part is figuring out how the power plays into it. When people are sad they cry, then they’re scared they scream and run away, when they’re happy they jump up and down, however, these aren’t just ordinary people. The tricky part (and often the fun one) is to figure out how the power reacts to this emotional cacophony. There’s a ton of different ways to do anything and the best part is it’s all up to you.
Happy Writing.
