Day 25 - Best anime villian
Medusa from Soul Eater
She is sinister, scheming, and incredibly cunning, allowing her to amass a small but effective entourage to carry out her plans. Her body contains 1,000 magical snakes which can be used as weapons called "Vector Arrows," as well as to place them inside the bodies of others to communicate with them telepathically or to kill them from the inside.
