No offensive material ocs
Ocs with offensive materials are no fun to have in a roleplay, so please don't. For all you know it could be offensive to someone.
Offensive material includes:
-Swearing/cursing
-Overly gore
-Nude/sexual
No mary-sues/Gary-stus
No-one likes these types of ocs. They're no fun to be around. So please, no mary-sues/gary-stus.
No over-powered ocs
These again are no fun. An example is that the oc can't be hurt in anyway. If you want a gem oc that as a power like future vision (like Sapphire) then just ask.
Be creative
Be creative with your oc. Boring and plain ocs with no quirks or no flaws are not fun.
You can always be a canon character just ask which one you wanna be! ^^
