Ranked by Magic:
This is how much magic the species possesses. You will see that some have magic but it has limitations. That is not accounted for, it's just the raw power they possess.
I want to emphasize that all these rankings also represent an average since some individuals can be less magic, talented, or strong than others, even if they are in the same species.
Elves- They can only use it once they reserve their power. Because of this, they can only use it every once and a while but when they do it could wipe out a whole Kingdom.
Witches- Depends on the person but the most powerful is right below the Elves.
Anges/Demons- They have power from being who they are but can't do anything with it so they have meaningless roles in their respective environments.
Fairies- Also depend on skill but they get most of their power from nature which is everywhere.
Dragons
Werewolves
Mermaids/Sirens
Vampires- They get the magic from blood.
Humans- Deja vu or "fate" is their little magic but not a lot.
Trolls- They are connected to nature but have no power over it.
Giants- They are just tall.
Rank by Strength:
Strength is physical, not mental. This can just be a special ability or just overall. Again this depends on the individual.
Dragons
Werewolves
Vampires
Giants- Bigger so lifting big things are easier.
Angels/Demons
Elves- Everything below is just normal strength individuals. They use their magic as their strength if they have any.
Mermaids/Sirens
Witches
Faires
Trolls
Humans
