Snow and Tigress

Snow and Tigress are cousins who are both single-form shapeshifters. These two are different yet alike in many ways. Snow is bubbly and very enthusiastic. She is often very easily hurt emotionally and can hold grudges for years. Tigress on the other hand is more chill. She is very "live and let go" when it comes to conflict. Unless you're trying to hurt her family. Then you dead. Tigress is extremely short and bullies used to try to push her around because of her size. Tigress, however, is an extremely tough girl and learned how to fight back in self defence. This is why, despite her small size, Tigress is extremely buff and not someone you would want to pick a fight with. Snow is more insecure about her abilities and often feels small beside Tigress, despite being the taller one. 
Power wise, Tigress is better at speed while Snow is better at stealth. Both are trained in combat in their animal forms. Tigress can fight in human form as well, Snow can too but is admittedly the weaker fighter of the two.
