It's a miss translation from the Ocean dub and original FUNImation dub of "over 8000". Dragon Ball Z Kai fixed it, but I'll answer either way.
In the Dragon Ball universe, the characters enhance physical strength and do special energy attacks with a force called Ki. Vegeta has a scouter that can detect the level of Ki a person has, and give it a numerical representation to connect the power with. At the time the show uses the line, 8000 was considered a high power level, despite later sagas having characters brush off strength in the billions.
I guarantee it's over 9000.
There are many companies that are ISO 9000 certified in India. The ISO 9000 was first published in 1987.
IT'S OVER 9000! *breaks the scouter in his hand* ''What 9000?!'' It eventually exceeded 21000 when Bulma checked via another scouter. ⌐_⌐ IT'S OVER... WAIT THE SCOUTER IS UPSIDE DOWN... IT'S *in not yelling voice* 1006. -_- It's less then 9000!! Vegeta actually says "It's over 8000!" but it was translated wrong from Japanese to English! Oh no!! Then Nappa should've yelled "What?! Only 8000?!!" After the Ginyu Force arrived on Planet Namek, Ginyu's scouter eventually read Goku's power level to be over 190,000 (or is it 180,000)!!! When he becomes SSJ, he goes to about 15 million.
yes,it's over 9000
Vegeta: Wait, let me get my scanner. Napa: Vegeta! Vegeta: It's 1006. Go get 'im, Napa. Napa: YES! *runs into battle, getting powned* Vegeta: Oops, had it upside-down. IT'S OVER 9000!!!!!!!!!! Napa: What, over 9000? *crushes scanner*
