[b]Commandment I: A Perfect Character is a Boring Character. [/b] Your character is strong, charismatic, gentle, loving, always wants to be the hero, and is the type of guy that everyone wants to be. STOP. RIGHT. THERE. If this character is everything we want to be, what's left for us to know? Why would we want to follow his story? He's already perfect. Think of every character you know, point out their flaws. They're not perfect, why is that? Because a good character has a good struggle. We want underdogs, underdogs that are expected to fail so that we can root for them. We want someone that has to work hard and fail bad when shit goes down. They can't win every time, that's repetitive and boring. Bad guys come, good guy fights, good guy wins. Too genetic, too obvious, and there's no point in hearing he story.

Now try this: Bad guys show up. Good guy comes and gets his ass kicked. Bad guys cripple him, kill his dog, and get away.

Losers. We want to see losers struggling to fight. Knights in shining armor are unrealistic, because shining armor only implies they've never been in battle.

"But what if I want my character to be a strong hero?"

Even Gods have their flaws. (Serious flaws too, have you looked into Greek mythology?) I can't create a struggle for each type of character you'd like.(That would take too long) Just remember that with great power, comes greater collateral/psychological damage. Even heroes have weaknesses. Make them hate themselves, make them overly attached to someone, make something stand out. Which brings me to my next commandant.

[b]Commandment ll: For the love of God, give them a personality. [/b] She's shy, but adventurous. She's a jerk, but has a heart of gold. She doesn't fit in, but loves making new friends. She's a bitch, but wants love. See the pattern? Because I don't.

YOUR CHARACTER IS NOT AND SHOULD NOT BE EVERYTHING.

"But I want people to like my character, so I want her to have a little of everything"

OCs are like real life people. (Shits about to get deep). Each character has distinctive personalities that separate them from everyone else. One does not satisfy everyone's taste, instead of being very flavorful, one flavor must be chosen. Because each person is a different taste, and no one likes tasting the same flavor all the time. (That sounded perverted)

Choose one single trait, ANY trait, and stick with it. "But my character is more complicated." Honey, they all are, just stick to a single trait.

I like to go with the inner person outer person rule. The outer person is the personality they show to the world. The inner person is WHY the outer person exists. 

In order, the outer person may be: hot headed, attention hog, slutty, quiet, or adventures.

While the inner person may be: Unsure how to make people like him, doesn't like being ignored, wants to prove to her parents that they failed, abused as a child an unsure what to speak about, or never knew how wonderful life was until they left home.

Y'see people are like onions, there are many layers to all of us. We only ever see the outer layer, but the inner layers are what made the outer layer grow.

[b]Commandment III: Just because their life is shitty, it doesn't mean we should feel sorry for them.[/b] Just because your character's parents died in a fire, on their birthday, after they left a letter saying how much they hate their kid, it doesn't mean we will instantly like the character. Nobody likes complainers, nobody likes whiners. Life is a tragedy, but pity is not something g we should give all the time. And sulking is not how we should live all the time.

It's alright if a tragedy makes your character behave a certain way, (like the onion advice I mentioned) but your entire character can't revolve around a single tragedy. "I'm going to betray all my friends, family and pets because I have a debt of twenty dollars to pay." Don't blow tragedies out of proportion.
