Key:

* Daizenshyus These levels came from the Japanese Mangas and Daizenshyus either by direct reading or calculation based on a direct reading. There is NO disputing these as they came from Toriyama himself! Ex: The manga states form 2 Freeza has over 1,000,000; or Vegeta: 18,000 * 10 (Oozaru) = 180,000

** Stated These levels are stated by characters in the JAPANESE version of DBZ through Scouter or otherwise. There is NO disputing these.

*** Guesstimate These levels are calculated based on Stated and Scouter levels as well as on a who can beat who basis. These are the only disputable levels.
