Kamehameha

Kamehameha is the most well known power attack it was originally created or thought of by old man or known as master rotie. It has been through the hole of dragonballs, dragonball Z and dragonball Gt series, it was the first power attack shown on dragonballs and was used by old man to put out fire mount for the Ox king ( Chi Chi's father). After seeing the attack goku sort of adopted the technique and destroyed a little red car. The Kamehameha was used also used by gohan and some other dragonball Z warriors at times, but is mostly known as goku technique In Dragonball Gt goku changed the kamehameha to x10 and etc which really increased the power of the Kamehameha but turned it to a red power beam instead of blue. Also in one of the last Gt episodes when goku and vegeta fused at ssj4 they did the most powerful Kamehameha to try and destroy the first star dragon, it was called big bang Kamehameha and was formed different to the original one and formed a ball then was blasted out wards, instead of forming in the hand then being released as a beam like the original Kamehameha .
