*if your character is a monster, one word: spikes
*remember countries you were told by the news that are evil are always evil, so make sure that any character that is Russian or of any Asian country besides Japan are evil.
*Women are either tom-boys or girly-girls, if you choose in-between make sure she's the most average person in the universe.
*every character should be the same age
*villains should always be as visibly opposite as your main character the same is true for personality and motive.
*villains represent the opposite of your beliefs and heroes represent your beliefs.
*your character can't be deep and philosophical if they aren't depressed. Optimistic should = foolish.
*go crazy with hair highlights, everyone has hair highlights.
*totally assume either non-US characters act either exactly the same as US characters with no cultural differences or are completely strange and savage.
*Everyone must be conventionally attractive, nobody is flawed, strange looking, or possesses any interesting unique facial features (like different facial proportions), this is especially true for women. You want as many of your characters to get romantic fanart as possible so make sure you represent that in every panel that all your girl characters are potentially interested in eachother.
*Breasts = humor, the bigger the breasts the more humorous it is if somebody falls into them.
*step-parents are always cruel
*if a guy is tough he will have a gravely voice and is a loner
*if a girl is tough that means she will express no emotions...because no emotions equals tough and cool
*a character can never contradict themselves, people never contradict themselves it doesn't exist in real life so assume characters that have contradictions are a result of bad writing.
*If you are making an alien race make sure to make them human looking enough to ensure you'll have enough alien hotties in your roster of characters.
*What's that? You still wanna make your character unconventionally attractive? Well okay, just make sure it matches a specific fetish and that every character in your story satisfies this criteria.
Uhhgg I made myself want to vomit writing these.
