The Evil Heart (in Japanese: エビル ヒアート, Ebiru Hiaato) is a demonic magic stone that absorbs the energy of whoever holds it upon contact and one of the many objects in Devil May Cry 2.
It flies at and attaches itself to the Protectorate member Lucia at the Uroboros factory located outside Uroboros City on Dumary Island. It began to drain both her powers and her life essence minute by minute. The Evil Heart was no more after it becomes the Electro Heart when Lucia quickly placed it into a power slot located within a laboratory inside the factory. Lucia then proceed to the other side of the factory to confront Arius.
