Shiva is the Gods' representative in the fifth round of Ragnarok. He is a prominent deity and the leader of the Hindu Pantheon. He is a Chief God and known as the "Cosmos' Bhairava," the "Strongest God of Destruction," and the greatest brawler in Heaven.
Shiva is introduced as a carefree, proud, and powerful God. However, he has shown violent tendencies, even against Zeus himself but stood down in respect of his senior. This is further reinforced when he boldly became shocked by what his opponent thinks of Ragnarok, stating that it is the best event.
