Kamehameha

Kamehameha (亀破波, かめはめは, Turtle Devastation Wave) is 's and Super Saiyan Goku's standard special move in Super Smash Flash 2. The move involves Goku (and under Kaiō-ken) or Super Saiyan Goku concentrate their Ki into a single point between their hands and then thrusts forward to shoot out a powerful streaming beam of ki. It is also Goku's signature move in both the manga and anime.

The Kamehameha is formed when cupped hands are drawn close to Goku's side and the ki is concentrated into a single point between the cupped hands (and the hands must be really close). The hands are then thrust forward to shoot out a streaming, powerful beam of energy. This attack has limited range, and decreases in power as it gains distance. Kamehameha goes through four initial stages (flashing and growing in size once every second: after the third stage it takes two seconds to reach the highest range) over approximately 5 seconds; then it maintains a constant size (and the range cannot be increased after reaching this point) but glows brighter, with the interior flashing. Continue holding it after it reaches the final stage, and it will continue to charge; after 20 flashes, it will release automatically. This is full charge. At point-blank range a fully charged Kamehameha does 51% damage. If done from a distance it will deal 34% damage. It is possible to release Kamehameha at any charge by releasing the special button (Stage I = 12% damage, stage II = 26% damage, stage III = 31% damage, stage IV = 51%). It can OHKO certain characters at close range when near the ledge or in the middle of a stage. It takes eleven seconds for the Kamehameha to be fully charged. Similar to the Falcon Punch; Goku has the ability to turn around while charging the move.

Kaiō-ken Kamehameha
When used by Kaiō-ken Goku, it is called the Kaiō-ken Kamehameha (界王拳・かめはめ波; World King Fist Turtle Devastation Wave). This attack is much faster and has better range but is weaker and cannot be fully charged unless the player immediately charges the attack once using Kaiō-ken, and releases it as soon as it is finished charging.

Super Kamehameha
When Super Saiyan Goku uses Kamehameha, it is called the Super Kamehameha (超かめはめ波, Chō Kamehameha) and is much more powerful and has a longer range. While charging up a Kamehameha in midair it will slow your descent. When Super Saiyan Goku releases a fully charged Super Kamehameha, the attack becomes known as the True Kamehameha (本場のかめはめ波, Honba no Kamehameha), turning into his SSJ3 form and releasing a giant wave of energy.
