I made a HP/Hamtaro themed OC! I saw some other's having HP-themed animal characters and was like "Heck I want one!!" So since I also love Hamtaro I decided to make a mix character. Based on Snape of course, since he's my favorite. I haven't decided if I want to name him Severus or Severham, so for now I'll call him Sev!

I imagine his owner me is a big HP fan and thus named her hamster after Snape, and him being a bit theatrical and loving that he was named after someone decided to basically adapt his personality a bit. And dress like him because aesthetic.
That or I'm going to name him Alan and he's just this cosplay/theater obsessed hamster that lives his life dressed up as different characters because his owner needs a life and finds him these outfits. Who knows.
