Goku using Kamehameha.
|Effect||Goku or Kaiō-ken Goku charges and then releases a massive beam of energy.|
When performed, Goku cups his hands to his side and concentrates his ki energy into a single ball-shaped point between them. Holding the special input charges the energy, and when the released, he then thrusts his hands forward to shoot it out in a streaming beam of energy, while uttering "HA". Kamehameha goes through four states of charge, with Goku utterring "KA","ME","HA","ME" and the energy ball flashing with each stage of charge, though after the third stage it takes two seconds to reach the fourth, full charge, which maintains a constant size and glows brighter. With each ascending charge, the beam becomes larger, travels more range, and deals more damage and knockback to opponents hit. At its lowest charge, the beam is weak and travels very little range, but at full charge, it is much more powerful and travels a great distance.
When being used in midair, the move dramatically slows Goku's descent while charging, pushes him back on release (with higher charges pushing him back more), and he can launch it backwards as well. The backwards-thrown version is called a Reverse Kamehameha, and behaves exactly the same as a normal Kamehameha.
Kaiō-ken Goku's version of the move is called Kaiō-ken Kamehameha (
The Kamehameha is Goku's signature move in the Dragon Ball franchise. It is the first Ki-based attack to be introduced in the franchise and continues to be the most commonly used, due to being not only iconic but also simple and practical. Master Roshi invented the technique, but took 50 years to develop it. Goku was not taught the move directly, but first learns it upon seeing Master Roshi perform it once in order to put out the fire on a burning mountain.
Even in the earliest points of the series, long before large-scale destruction was a common occurrence, its destructive power and reach were supernatural in magnitude. Along with destroying the aforementioned mountain, it was also used to destroy the Moon to stop Goku, rampaging as a Great Ape, from destroying the World Tournament.
Being such a common attack, it was natural for variations to spring up as the series went on. Out of the variants that appear in Super Smash Flash 2, the Feet Kamehameha, seen in his down aerial, is first used by Goku against Piccolo, the Reverse Kamehameha was first used by Master Roshi — disguised as "Jackie Chun" — against Goku, and the Kaiō-ken Kamehameha was used notably against Vegeta IV and Frieza. All variants tend to appear as separate attacks from each other in the video game adaptations.
- In its first appearance in v0.7 of the demo, the fully-charged Kamehameha was the single most damaging attack — barring Final Smashes — in any version of SSF2, dealing 51% damage. Its power was significantly reduced in later versions.
- Prior to v0.9b, the interior of the stored energy would flash at full charge. While this trait has been removed from the regular version, it still occurs with Kaiō-ken Kamehameha.
- The Kaiō-Ken Kamehameha went through a number of drastic changes between versions of the demo. In v0.8a, Goku skipped the charge entirely, instead immediately releasing a stage 3 Kamehameha. In v0.8b, the charging returned, but it is quite difficult to fully charge as the Kaiō-Ken would most likely run out an instant after stage 3 began, interrupting it.
