I still like the idea of Ralsei being Kris' monstersona, but it seems less likely now.
Especially because Kris seems to be a dog kinda furry actually.

No he's not. When you look at the fridge while Susie is around, Kris starts autistically pointing out all the differences between Asriel and Ralsei. Ralsei is gonna turn out to be Kris's childhood monstersona.
