oooug OC decisions

Hello world!!
I was going to submit an OC so I made myself a template... but the problem is...

I DON'T HAVE AN OC READY!!

I'm really indecisive on which OC I should roleplay with... What kind of OC would you guys like to roleplay with?
I have almost any kind of OC made for most settings such as sci-fi, fantasy, and more. I have OCs that are completely original and then there's OCs that are based on shows such as Murder Drones, BFDI, and corru.observer.
