Simhika got the boon from Brahma that she can control anyone's shadow. Later, she controlled Devi Chhaya, mother of Lord Shani and wife of Surya, the sun god. And eventually got defeated by Shani and Hanuman. Simhika was forgiven by Hanuman, but he told her that whenever he finds her in later phase of life he'll kill her. Later, when Hanuman was climbing the ocean to Lanka, the kingdom of Demon Ravana, Simhika was hiding in the ocean and captured Hanuman's shadow, Hanuman dived into her mouth and came out tearing up her stomach, ending the life of Simhika.
