Shatrughna (Sanskrit: शत्रुघ्न, romanized: śatrughna, lit. 'killer of enemies') is a prince of Ayodhya, King of Madhupura and Vidisha, and a brother of Prince Rama in the Hindu epic Ramayana. He is also known as Ripudaman (vanquisher of foes). He is the twin of Lakshmana. He is a loyalist of Bharata, just like Lakshmana is to Rama. According to the Valmiki Ramayana, Shatrughna is the re incarnarnation of Sudarshana Chakra (Rama). Shatrughna also appears as the 412th name of Vishnu in the Vishnu Sahasranama of the Mahabharata. According to the Ramayana, Rama is the seventh avatar of Vishnu, while Lakshmana, Shatrughna, and Bharata are the avatars of Sheshanaga, Panchajanya, and the Sudarshana Chakra respectively.
