Ah the bread to the butter of any plot: the characters. These people (or celestial beings) are the reason readers will stay with your books. And while you can and should write the characters you want to, there are some unspoken rules that you should be aware of.
Character stereotypes and how to use them
Of course no one wants to have stereotype character. But like every clique, stereotypes can be useful if you know how to use them. The buff love rival adds conflict and stakes. The red herring gives a twist to the mystery. Look at the standard stereotypes for your genres, hell for stories in general because they are the key to a good story as much as any plot.
There are so many character templates for any questions you may face about your characters and they are all free to use and download.
Why should we care about them?
Remember that your characters are more than just a pretty face. They need to have dreams and hobbies, something that a reader can attach to. The best way of doing that is giving your characters’ flaws, these are both things to overcome and also be used as a source of conflict and weakness. Flaws can be fears, prejudices or even bad experiences that they can’t let go of. Whatever it is, their flaws should tie into their arcs.
They’re not clones
Most likely, your characters are not exact copies of each other. They all have different experiences, thoughts and voices. Remember this when writing because without this, your writing will feel flat. These changes can come from a number of different places:
Characters are what hold the plot together and perfecting them is hard, just take your time and get to know them as closely as your best friends. Good Luck Xx.
