Here are a few figures I'd like to see in future books.
Krampus bad cop to Santa's good cop.
Baba Yaga the wicked witch of  eastern European folklore
Loki the problem child of Asgard.
coyote the class clown of western Native American mythology.

Share the mythological figures you'd like see and why you like them
