Super Kamehameha

Super Kamehameha is Super Saiyan Goku's standard special move in Super Smash Flash 2.

Overview
When inputted, Super Saiyan Goku puts his hands to his side in a shell-like position, then concentrates his Ki to make a ball-shaped energy point, that gets bigger as the special button is held. When the button is released, Goku then thrusts his hands forwards, releasing a giant beam of energy. It is an advanced and more powerful version of 's Kamehameha.

True Kamehameha
When the move is fully-charged, it starts being referred to as True Kamehameha, turning Goku into his Super Saiyan 3 form and releasing an enormous wave of energy, with even greater range. The name of the move comes from Raging Blast, a Dragon Ball Z game.

Origin
Goku first uses the attack against Piccolo during the 23rd World Martial Arts Tournament. Later, Super Saiyan Goku uses the Super Kamehameha in an attempt to repel Frieza's Nova Strike during the titanic battle on Namek, but Frieza manages to escape the energy wave and rams Goku into the ground.

Cell uses the Super Kamehameha against Goku during their match in the Cell Games. He later uses upgraded versions against Super Saiyan 2 Gohan.

The Super Kamehameha is frequently used in many Dragon Ball Z video games, such as Dragon Ball: Daimaō Fukkatsu, Dragon Ball Z: Goku Hishōden, the Budokai series, the Budokai Tenkaichi series, Dragon Ball Z: Battle of Z, and Xenoverse series; it is a common staple on many characters' movesets. It is also Adult Gohan's Ultimate KO in Dragon Ball Z: Supersonic Warriors 2, as well as Goku and Cell's regular super Dragon Ball: Tap Battle.

True Kamehameha
When Kid Buu fires a Super Kamehameha at Goku, he blocks it and fires the True Kamehameha. Kid Buu manages to deflect it to the side, but loses his right hand and left arm in the process. Goku calls it the True Kamehameha when insulting Kid Buu, claiming Buu's Kamehameha is merely a cheap imitation.

While fighting Beerus on King Kai's Planet, Super Saiyan 3 Goku attempts to hit Beerus with his True Kamehameha twice, in the first time, Beerus easily blocks the attack with his finger, and in the second time, he simply dodges out of the way and gets behind Goku, causing the attack to blow a hole through King Kai's planet.

Goku also uses a similarly powerful Kamehameha as a Super Saiyan 3 in the Dream 9 Toriko & One Piece & Dragon Ball Z Super Collaboration Special, in order to deal the final blow to the monster Akami.
