Mahākāla (English spelling)

Japanese: Mahākāla（英語表記）Mahakala

…He is also considered the founder of dance, and is called Nataraja (the king of dancers). Furthermore, when he destroys the world, he assumes a terrifying black form, and is therefore called Mahākāla (the Great Black). He is also called Pashupati (the Lord of Beasts), and later a sect of Shaivism called Pashupata (the Lord of Beasts) was formed. …

From Shiva

…While Brahma is the creator of the world and Vishnu is the maintainer of the world, Shiva is the destroyer of the world. He is called Mahākāla (Daikoku) because he appears in a frightening black form when he destroys the world. He is also known as the destroyer of three cities because he pierced and burned the three cities of the devil (Tripura) made of gold, silver, and iron with a single arrow.

From [Daikokuten]

...The Sanskrit word Mahākāla is translated as Mokākāra, Mahakara-ten, Daikoku-shin, or Daikoku-tenjin. He is the incarnation of Mahāshurā (Daijazāten) and the god of war.
