Cartoons you can roleplay/roleplay as ocs or real characters for are:
GRAVITY FALLS (new edition to this studio, enjoy rping as the mystery twins)
Fairly Odd parents
Mlp (My little Pony)
Doctor Who (Not a cartoon but WHO (get it?!) CARES!?)
Warriors (Not a cartoon either... unless you count sss)
Portal (Also not a cartoon... XD)
I will add a new one to roleplay as but not yet... it's a secret one based on a quick series of stories that I plan on writing (about birds)
You may be more than one character in a comment
you may use ocs or real charcters.
You must reply to comments when joining a roleplay unless youre starting a new topic/story.
you may be a character someone else is if they are real characters from the show and you're not contradictiing what another says (unless theyre in a differnt RP)
If you have an oc make a project for them if not then just be an existing character fromm the shows metioned.
like I said don't stick to one character... unless you really want to.
