There are very few policies which apply across all Wikia. These can be found on the Central Wikia at Wikia:Category:Policy.
Vandalism is prohibited and will be punishable with a warning, temporary ban, or a permanent ban depending on the severity of the vandalism.
Bullying other users is against the rules.
Sockpuppetry (creating a different account usually to avoid a ban) is prohibited and will result in a permanent ban. If you need to create a new account for a harmless reason please let the admins know.
The Character style should go:
Section: History. This should include the full history of the character.
Section: Personality. If the character has a personality, this should be added so readers understand the character's personality.
Section: Gallery. This should include pictures of the character if they are seen.
Section: Trivia. This should include facts about the character. This shouldn't be to obvious or uninteresting.
[[Category:Policy]] to any policy pages will add them to the policy category. This is found here.
