i actually have quite a few characters some names i have no idea where they came from i will just think of them like kymura i feel like ive seen the name somewhere but i havent (or i just dont remember)
ive also came up with tamaki (who i named after a lm soundfile XD )
and of course my main fursona afkinz the idiotic oversized antlered tabby cat...
i usually base my characters personality off myself and their backstorys i will just try take any normal thing (such as both parents are dead) and i will twist it (quite often i will have the character such as tamaki and afkinz to be results of animal testing so they wont have parents but then theres warrior who woke up in the middle of nowhere with no idea where he came from
