Aghasura

Aghasura (Sanskrit: अघासुर) is an asura featured in Hindu literature, most notably in the Bhagavata Purana.

He was one of Kamsa's generals,[1][2] and the elder brother of the demoness Putana and Bakasura.

[3] The killing of Aghasura by Krishna is narrated by the sage Shuka to King Parikshit in the Bhagavata Purana.

[10] In response, the demon also extended his own body's size, but started suffocating as Krishna was expanding more quickly than him, causing his eyes to pop out.

[11] The demon's life force, however, could not pass through any outlet, and therefore burst out through a hole in the top of Agasura's head, meeting his end in Krishna's hand.
