He came out early in the Z saga, as a bad guy who killed his pal Nappa, who made the rest of the Z team besides Goku look like jelly.
Even after he was defeated on Earth, he managed to forge an uneasy alliance with Krillin, and Gohan.
Loved seeing him kill Zarbon.
He did pretty good against Guldo.
His raged assault against Recoome was impressive.
He did well and bad against Freiza's forms.
But all good things must come to an end.
After being wished back, he's man enough to wear pink. And cry in his sleep that he's not Aryan like Goku and the mysterious guy from the future.
Him and Bulma fighting was classic. I love the surprise when you find out that they get married (I guess) and have a son named Trunks.
He came in all confident when Android 19 had Goku pinned to the ground.
He made short work out the first two androids, until the next two are unleashed.
He was killer during his fight with Semi-Perfect Cell. Idiot did let him absorb 18.
I also loved it when he broke the punching machine into pieces.
I did find it kinda stupid when he turned into Majin Vegeta.
Way to end of the world dude.
So after dying a heroic death, he finds out that he just had an epic fail.
So he then turns into Vegito with Goku, and awesomeness happens.
His final moments and personality shined during the fight with Kid Buu too.
