In Hindu lore, the god known for taking forms as various avatars is Vishnu. He is part of the Hindu trinity (Trimurti) along with Brahma and Shiva. Vishnu's avatars, such as Rama and Krishna, manifest to restore cosmic order (dharma) whenever it is threatened by evil forces. Each avatar has a unique story and purpose, highlighting different attributes and teachings. Vishnu's ability to take diverse forms underscores the concept of divine intervention in maintaining balance in the universe.
