Known as the king of the Demon Realm, Dabura was a slave to Babidi's mind control, making him his most powerful subordinate before Majin Buu is resurrected.
He was the one responsible for turning Krillin and Piccolo into stone with his spit, before Goku and the rest followed him and Babidi to their base of operations. He later fought on equal levels with Gohan in a one-on-one match, which was cut short when he took note of Vegeta's evil spirit, seeing another potential servant for Babidi. When Majin Buu is finally brought back, Dabura is disposed of by his master. Seeing Buu as far too big of a threat, Dabura tries to kill him, but fails, as Buu turns him into a cookie to indulge in.
In the afterlife, Dabura is eventually rehabilitated, having been rejected from Hell, given that it was his natural habitat to begin with. He is seen occupying Heaven along with the spirits of Videl, Bulma and Chi Chi, well after Buu's annihilation of the human race.
