Lord Ayyappa: Lord Ayyappa is the son of Vishnu and Shiva a very popular Hindu deity. Ayyappa was born out of the union between God Shiva and Mohini, an avatar of Lord Vishnu. Goddess Durga killed the demon Mahishasura, and his sister, Mahishi set out to avenge her brother's death. Mahishi had a boon from Lord Brahma that only a child born of Lord Vishnu and Shiva could slay her, so she was indestructible. To save the world from annihilation, Lord Vishnu incarnated as Mohini and wed Shiva, and thus Lord Ayyappa was born.
