It's Over 9000!

", is an Internet meme that became popular in 2006, involving a change made for English localizations of an episode of the Dragon Ball Z anime television series titled "The Return of Goku", which originally aired on April 19, 1997.

Aliens serving the galactic tyrant Frieza possess "scouters," devices that duplicate this ability technologically and can quantify different combatants' power levels objectively, though warriors can employ ki-manipulation techniques to mask the full extent of their strength.

[1] He noted that the Daizenshuu 7 book quoted the dubbing team as saying that speaking "9000" in English was a better fit for Vegeta's animated mouth movements; on the other hand, Elvy made the assertion that Dragon Ball Z's Ocean dub "was notorious for making translation errors (such as Goku believing Vegeta killed Grandpa Gohan or Bardock being a so-called "great scientist") which can't be explained away so easily".

[1] An edited video clip of the scene from the episode was originally uploaded by YouTuber Weston "Kajetokun" Durant on October 17, 2006, as an inside joke for his friends, making fun of how Drummond phrased the English line to fit Vegeta's on-screen mouth movements, which were animated to fit the original Japanese line.
