One of Vegeta his best lines
--------------------------------------------------------------------------------------------------------------------------------------------------
What clown? Are you feeling angry? Humiliated? Is that it? Fool! You don't know what humiliation is! Don't worry I will teach you how it taste, just how you have taught me. Me, a warrior elite. At my fingertips I held the power to destroy entire worlds. I am a Saiyan of royal blood. The last of our kind. And on my shoulders rest the glory of an extinct warrior race. Whole civilizations once trembled at the sound of my name. But you didn't, did you Kakarot? And at your hands, your COMMON hands, my honor and my pride, the foundations on which I ALWAYS stood, began to crumble at my feet. It was at your hands I suffered my first great humiliation, toppled by a piece of low-level trash! It is time to take back what is mine. I will NOT live my life as your second. That time is over, every breath you take is an assault to my honor. But no more, Kakarot. By MY hands, you will be cut down inch by inch, the way YOU have cut down my pride!

Meaningless, huh?! What do you know of meaningless?! Spend most of your life ruled by another! Watch your race dwindle to a handful! And then, tell me what has more meaning than your own strength! I have been made the blood of a Saiyan prince; he [Goku] is nothing but a joke! Yet, I had to watch him surpass e in strength. My destiny, thrown to the waste-side! He’s.. He’s even saved my life as if I were a helpless child. He has stolen my honor. And his debts… Must be paid.

Silly robot, do you really believe you have any chance against a Super Saiyan like me? Your circuits must be malfunctioning. Fresh out of the factory with no warranty and already broken. Such a pity.
