Don’t worry despite the title your characters can still be great heroes but behind every hero is a person and here I am planning to help you flesh him/her out.
I believe everyone reading this already know this but I’m saying it again.
Your character is not allowed to be perfect.
Your characters isn’t allowed to be loved by everyone or allowed to be able to do everything perfectly.
What your character is allowed is human traits such as flaws, fears, past failure and so on.
Since this post is supposed to be on creating characters I think I won’t give you a speech on characters and instead simply share how you can go about creating them.
This is my method. (I call it building bridges)
Everyone has a past and it doesn’t even have to be a messy one to be significant. It can range from having your parents murdered to being middle child in a house with too many children.
Now I build a bridge and see how it affect the characters personality.
Fears can come in packs it starts with the big fear which creates the smaller fears.
I decide on the great fear by looking at the characters past.
Using the example of parents being murdered we can say the characters fear is being helpless which can lead to smaller fears such as fear of being sick.
Using the middle child example we can say the big fear is being underappreciated which can lead to the smaller fear of losing.
( it isn’t so much the fear that matters it’s how it is handled)
Now I build another bridge
Flaws are not always a weakness it is simply a part of being human .
Flaws can come in packs like the fears one big one with a few smaller ones.
Now again using the character whose parents were murdered and whose fear is being helpless we can say that because he fears being helpless he feels the need to do everything personally and thus his flaw is being a control freak and not letting people help him.
Using the middle child who fears being underappreciated we can say that because of his fear he is very competitive and treats everything like a contest.
Hopefully you understand the method by now.
It is basically everything is made out of smaller things and every action has a reaction.
The minute you understand this you can use it for the rest of your character which includes a quirk and how they treat people , what drives them and so on and so on.
