Vischnu, by force or fraud, overcomes them all.
His first Avatar is of the Fish, as related in the Mahabharata.

The object was to recover the Vedas, which had been stolen by a demon from Brahma when asleep.

In consequence of this loss the human race became corrupt, and were destroyed by a deluge, except a pious prince and seven holy men who were saved in a ship.

Vischnu, as a large fish, drew the ship safely over the water, killed the demon, and recovered the Vedas.

The second Avatar was in a Turtle, to make the drink of immortality.
