When you have an oc with antlers, there are certain things to think about..
I have a reindeer oc named Beige, and there's certain things I have to take into consideration when designing a story for him. For one, all of his shirts and jackets must have a zipper (or buttons) in either the front, back, or side, because he can't just pull a shirt over his head with antlers.
Also, he rides a bike everywhere, because there's not enough head room in a car for his antlers.
He has to have his bed in the middle of his room to leave space for his antlers, or else he scratches up his wall in his sleep.
Beige came from a colder climate, with many reindeer citizens, but had to move to a new city where there are very few. People are cruel, so I imagine him to be picked on a lot for being different. I imagine a lot of antler tugging, trying to clothesline him, hanging things in his antlers, etc. Due to the bullying he prefers to keep to himself, is very cautious and shy, with trust and confidence issues.
He's such a cute character though. Hopefully I'll be able to build a story around him soon.
