>>35324310It's a character version of what you see yourself as in the form of an animal you like
For example, if I'm a nerdy dog lover, I might design a lanky golden retriever who wears glasses and a bowtie. Alternatively I could imagine myself as a muscular rottweiler who's easily to get along with and fucks all the ladies he comes across.
You can go on to add other stuff like clothing and personality traits, but that's the basics of a fursona.
A pokesona is just that but a Pokemon as your character. So like an Arcanine or a Rockruff.
