on this note, I think Vegeta's characterization in super would make more sense if they had stuck with him
edit Oh, and something else
Vegeta briefly gives up trying to surpass Goku in the fucking Namek Saga, when he gets wished back to life he see's Goku as a super Saiyan, and his reaction is to smile at Goku and basically thank him for giving Vegeta's life closure by killing Frieza and avenging the extinction of their race
cut to three eps later, he still hates Goku and wants to surpass him for some reason
Vegeta's rivalry with Goku never really made sense
he'd go from being sweet and reformed one second to being a genocidal maniac the next
Saiyan Saga, Vegeta gets shown Mercy by Goku and re-evaluates his choices,
cut to namek Saga, kills a Namekian villiage for no reason, gets killed and cries recounting the years of tourment Frieza put him through making him what he is now and begs Goku to kill Frieza so he can never do what he did to Vegeta to anyone else, Goku does and wishes him back. Vegeta thanks Goku and smiles at him
3 episodes later Vegeta hates him again for some reason...then he marries Bulma and has a kid and seems fully content with human life
then the Androids show up Goku has a heart Attack and vegeta becomes Bloodthirsty again
Vegeta loses to cell, feels like an idiot, becomes loving again
cut to the Buu Saga, Vegeta is suddenly evil again, then has a touching scene with Trunks, stops being evil again and dies
then at the end he decides it's best if he gives up trying to best Goku and just focuses on his new life with his family
then Super throws his concession of defeat out so he can still be Goku's bitter rival
