Question: what are dbz characters named after?
Answer: Saiyans are all named after vegetables. Vegeta, both the prince, his king father and the Saiyan home planet (originally named Planet Plant), means Vegetable; Raditz is 'radish', and Kakkorotto is 'carrot'. The villain Freeza (originally Friezer) comes obvious, and his brother Cooler and their father King Cold.
