The Tripura demons
The three sons of Taraka who won from Brahma three flying cities of iron, silver and gold, built by the architect Maya, that could be destroyed only by one arrow at the moment they aligned; Shiva burned them with a single shot from a chariot made of the cosmos. Wikipedia's Bhimashankar page attaches a demon called Tripura to that shrine too.
