Goku vs Vegeta / Kamehameha vs Galick gun / dragon ball

As Saiyans, our worth as warriors is measured and judged at birth. Those with no potential like you are sent to inferior planets like this. Thrown away and forgotten like the garbage you are. With enough hard work and training, even garbage can surpass the elite. Ha ha ha, that's quite a sense of humor you've got. You're about to learn the hard way that effort alone isn't enough to reach my level!
