A Kāmāvacara god, Devadatta, in a previous birth.

He appeared to men on fast days and admonished them to lead evil lives.

Once he met Dhamma (the Bodhisatta), and the two had a discussion in mid-air, at the end of which Adhamma plunged headlong into hell (J.iv.100-3).

His vehicle was called Adhammayāna.
