Simhika (Sanskrit: सिंहिका, romanized: Siṃhikā) is a rakshasi in Hinduism.

[1] In the Ramayana, after meeting Mainaka and Surasa, when Hanuman was crossing the ocean to Lanka, the kingdom of the rakshasa-king Ravana.

Even as he flew overhead, she captured Hanuman's shadow with her magic.

According to one account, forewarned about this creature by Sugriva, he expanded his size, and observed her vulnerability when she followed suit.

He turned himself small and allowed her to swallow him, ripping her apart from within, slaying her before he resumed his journey.
