Dragon Hammer

Dragon Hammer[1] is a combination of the 10x Kamehameha and Dragon Fist used by Goku in his Super Saiyan 4 form. A technique also used with a combination of the God Kamehameha and Super God Fist used by Goku in his Super Saiyan Blue Kaio-ken form.

Overview
Goku fires the 10x Kamehameha directly at the opponent's chest. Then, while the beam is blasting the enemy, Goku flies through the attack and punches the opponent in their stomach with the Dragon Fist. Finally, Goku charges more power into the attack, resulting in the golden dragon overpowering the opponent as it coils around them and pierces through their stomach, inflicting a huge amount of damage.

Goku uses this attack during his battle against Omega Shenron. After Goku recovers his sense of sight, Omega Shenron still believes Goku is blind and even taunts him by allowing him to attack. At that moment, Goku fools Omega Shenron by suddenly opening his eyes and attacking him with the Dragon Hammer, seemingly destroying the Shadow Dragon. However, the victory is short-lived, as Omega Shenron survives by regenerating himself using Rage Shenron's technique, Electric Slime Body Built and continues the fight.

In the movie ''Dragon Ball: Yo! Son Goku and His Friends Return!!'', Goku uses a similar attack to defeat Aka (although the golden dragon at the end of the attack is not present).

In Dragon Ball Super (anime) Goku fires a fully charged 10x God Kamehameha at his opponent and then charges through the Kamehameha using a Super God Fist to end the attack off. Goku uses this attack against Hit but Hit uses Time-Skip to dodge it.
