This is so random, but it came to mind and since it's media origin is so versatile, I think the roleplay could be too.

I love cartoons. I just do. Children's animation, adult animation -- everything. If it wasn't obvious enough by my Felix the Cat profile picture (because yes, that's him.) Anyway, I recently began rewatching Steven Universe. Along with that, I had a super unrelated dystopia conformity-theme type dream and it was super weird. But anyway, it got me thinking that something with the same vibe and feel as Steven Universe's [i]Homeworld[/i] endeavours would be super interesting. You know, unique beings all created for set purposes operating under something greater. 

Bonus points if you actually know Steven Universe... I would say it's not required but since the entire concept hinges on the knowledge of Steven Universe, I think it might be, just a little.
