From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
The Dodohameha (どどはめ波, Dodohameha) is a combination of the Dodonpa and the Kamehameha and used by Tiencha. Tiencha draws his hands behind his back and charges two golden-yellow energy spheres around his hands. He then shouts, "Dodohameha!" and brings his hands together in front to fire a large energy sphere at the opponent, inflicting a high amount of damage.
Dodohameha is named in Dragon Ball Z: Budokai 2 and is one of Tiencha's attacks.
