A devarāja, the god of rain. He was subject to the will of Sakka, and the books contain instances of his causing rain to fall at the command of Sakka (J.i.330; Mhv.xxi.31; J.iv.253).

He was also influenced by the exercise of asseveration of truth (saccakiriyā) e.g., J.i.331 f. Buddhaghosa (SA.i.64) describes him as Vassavalāhaka, and says that he was an inhabitant of the Cātummahārājika deva realm. Kokanadā and Cūḷa-Kokanadā were his daughters (S.i.29 f).

Pajjunna is mentioned among the Mahā-yakkhā to be invoked in time of need (D.iii.205), and he was present at the teaching of the Mahāsamaya Sutta. Ibid., ii.260.
