Kamehameha - Goku's signature move, taught to him by Master Roshi.
Kaioken - Taught to him after his first death by King Kai while training for the fight against Vegeta and Nappa in DBZ. The Kaioken Attack doubles the user's powers at an increasingly powerful force, but if one does not have a high ki level, it can be detrimental to the user's health.
Spirit Bomb (Genki Dama) - Taught to him by King Kai, the Spirit Bomb gathers energy from all living things and creates a gigantic ball of ki.
The Ultimate Ki Bast - Taught to him by his former enemy, the Legendary Super Saiyan Broly, its the most powerful attack in the DBAF world. Only Goku and Broly can use this attack. but only after surpassing Super Saiyan 4. After the attack is finished Goku will turn back to regular form. This blast can destroy planets while being charged, adding to its dangerous power. Far stronger than the Spirit Bomb, Broly first mastered this technique when his rage broke loose.
