Anime: Soul Eater
Now this anime is a great example of a concept being done great (unlike SAO *Cough*)
Medusa herself is a Hero-Turned-Evil โ she used to be a student and nurse at Death Weapon Meister Academy but then got the brilliant (not) idea to revive Asura.
Medusaโs design is a cloaked creature with slightly green pale skin and tired eyes.
This in itself is a reference to the greek Medusa, but now itโs more goth-y.
And it seems goth runs in the family!
Her daughter Crona is also a goth swordsman, and although she didnโt make the list she should be mentioned.
