The exact opposite of Animal Cruelty, this category includes heroes who are kind and friendly to animals (cats, dogs, birds, amphibians, dinosaurs, apes, fish, rabbits, reptiles, rodents, insects, etc.), have saved their lives, or have an interest in animals.

Some of them have difficulty with human interaction, often because they fear or dislike humanity because of their common abuse or mistreatment of animals until they know the true meaning of family, friendship and/or love.

NOTE: Do not add heroes who are Animals themselves to this category, unless exceptions are found: for instance, if said character is an anthropomorphic animal and is kind to non-anthropomorphic animals, they can count for this category. Animals that are kind to other animals can fit under Philanthropists.
