Key:
Color	Type	What It Means
1,000,000	Manga	These powerlevels were never stated in the series, but were stated in the Japanese Mangas (mostly Dragon Ball Daizenshyu 7). There is NO disputing these. They came from Toriyama himself!
1,000,000	Scouter Reading	These levels cam directly from scouter readings in the JAPANESE version of DBZ. Ex: "Hmm.. the scouter only says 5,000."
1,000,000	Stated	These levels are stated by characters in the JAPANESE version of DBZ. Ex: "His powerlevel is more like 90,000" or "Sybamen have 1,200 each"
1,000,000	Guess-timate	These levels are calculated based on Stated and Scouter levels as well as "who can beat who" Ex: Gohan can beat Cell, so his level is higher.
