Frieza and Goku in “Unfinished Business”

Poor stupid Saiyan! You honestly think you've won? Your puny mind never could understand! I am Frieza, the most powerful being in the universe! And you are nothing but a beast! A fragile animal! You can't win, because I am mighty! And you, are not! Now learn! Learn what happens when you mess with the most powerful being in the universe! [while Goku flies away, Frieza blasts Goku from behind]

Huh? You fool! Ha! [Goku throws back his own blast, which goes through Frieza's and hits Frieza, completely burning his body]

Aah! Ahh! AAH!
