Name Puns

Vegeta: Obvious pun on vegetable. This is why vegeta is the correct spelling.
*Note: Most saiyajins' names have to do with vegetables. Goku and Goten have to do with the sky, and Goku, his tail, and his nyo-boi are all coincidental with monkeys. Akira Toriyama got the idea for Son Gokuu by the Chinese fairy tail/legend of the monkey king with his staff (and of course his tail). When Son Goku is written out in Chinese, it looks like monkey. This is where all of this monkey stuff came from*
