Most of the time people like to do oc alicorns because alicorns are somewhat special and rare. But 90% of the time most alicorn ocs l see are not even royalty or even a special creature. I only have 2 alicorn ocs and there is a proper reason for them to be one because they're royalty. imo its weird for most people to make a random oc who is a plain pony that lives in a normal life to be an alicorn. Sorry for anyone who has an oc like that, l'm just being honest. I don't mind people for making those kinda oc characters, I just think it can be a little off.
