Vyomasura

[2] Following the slaying of the horse-asura Keshi by Krishna and Narada's salutation of him, the deity tended the cattle along a mountain slope along with the gopas, the cow-herding youth.

Vyoma, a magically-gifted asura who was the son of Mayasura, disguised himself as a youth, and played the part of a cattle-lifter, stealing away a number of the boys who posed as goats and other creatures.

Realising that his friends had been taken captive, Krishna caught hold of this asura, "as a lion would do a jackal".

Mayasura assumed his true form as a massive mountain to escape from the deity's clutches, but to no avail.

Krishna hurled him against the earth and suffocated him, even as the devas witnessed this act, and liberated his friends by breaking open the seals of the caves.
