Veerbhadra

Veerbhadra was a powerful being created from the wrath of Lord Shiva. This manifestation was quite fearsome in appearance and larger than life, while also being more powerful than all the Gods.

Daksha Prajapati was a son of Lord Brahma and the father of many daughters, including Dakshayini or Sati.

Dakshayini had a wish to get married to Lord Shiva but Daksha objected as he didn't respect Lord Shiva as much as the other Gods.

Daksha held a Yagna where he invited all the Devas instead of Lord Shiva, who Daksha considered unsuitable.

Shiva had still arrived at the Yagna with his ganas. He was not greeted by Daksha and Dakshayani couldn't stand this humiliation.

Dakshayini jumped into the sacrificial fire and this angered Lord Shiva. He manifested as a demon named Veerbhadra, destroyed Daksha's Yagna, trampled on Indra, broke Yama's staff and killed Daksha by beheading him.

After this incident, Lord Brahma himself prayed to Lord Shiva to forgive all the Gods and return Daksha's life. Lord Shiva agreed to it and gave back Daksha's life and replaced his head with that of a goat. He also undid all the damage that he had caused.

Then Lord Shiva was invited to the Yagna and all the Gods respected him henceforth, including Daksha. Such is the greatness of Lord Shiva and his Veerbhadra Avatar.
