Dabura is the king of a Demon Realm, and Babidi's right-hand man, being placed under his control by a spell. Dabura has the special power of turning his enemies to stone, simply by spitting on them. His name is originally taken from a Japanese pronunciation of the last half of the incantation "Abracadabra."

It is mentioned by Goku that Dabura's power is equal to Perfect Cell's.
