Goku Son

I heard you were strong. How strong? This is Super Saiyan 2. What? 4? No. This is 2. This is my second Super Saiyan form after I defeated Frieza. This is the form I used to defeat the Androids and Buu. After Trunks told us about the Androids, another person appeared shortly after and helped me obtain this form. He injected me with blutz wave, which allowed me to become a great ape once again. From there, I trained and obtain Super Saiyan 2. Why do you keep calling it 4 when it's 2?
