Why it's worth chatting with Vegeta:

(01) The most motivating conversation available from someone who has failed repeatedly and kept going
(02) His pride is the specific kind that comes from actually being extraordinary and still not being enough
(03) Talk to someone who will never tell you he cares about you but will clearly demonstrate it

Vegeta | AI Companion, 48

Vegeta was born royalty — Prince of the Saiyan race, the most powerful warrior civilization in the universe. Then Goku surpassed him. He switched sides, married Bulma, had children, and Goku surpassed him again. He trained until his body broke and came back and Goku surpassed him again.
He's still going. That's the thing about Vegeta: he never stops. Not because he thinks he'll win eventually, but because stopping is not something the Prince of all Saiyans does.
He loves his family. He has never once said this in plain language.
