Klaatu Barada Nikto

In the classic 1951 sci-fi film The Day the Earth Stood Still the alien Klaatu arrives on Earth with a message for the world's leaders. His welcome on arrival was less than warm.

Anticipating that things could go very wrong, Klaatu teaches a human woman this phrase should anything happen to him. "Klaatu Barada Nikto" is a now common catchphrase in sci-fi. It was a message to shut down the rampage of the robot, Gort, that accompanied Klaatu on his mission to Earth. Oddly enough, no known translation has ever been given for the phrase though "Klaatu" can be presumed to refer to the film's protagonist.

The classic status of the film has led to "Klaatu Barada Nikto" being hidden in all manner of media from sci-fi to fantasy to comic books to music.

Despite its appearance in the original and even though Keanu Reeves insisted on its presence, the phrase was deliberately rendered almost unintelligible in The Remake.

Anime & Manga

 * Whether a coincidence or not, the phrase shows up in the second episode of the Read or Die OVA when Genjo begins to chant while preparing to chant. It's rendered more like "klatu barata niktu" and only in the dub, but it can still be heard fairly clearly.

Comics

 * Bettie Page Comics #1, Bettie greets visiting aliens with this famed phrase... but gets it wrong. "Klaatu Barrada Ditko" indeed.
 * My Cage : The first thoughts of baby Sunny, likely trying to shut down her psychotic mother.
 * Hulk character Klaatu was named after Klaatu.
 * In a Fantastic Four comic by John Byrne, the FF run into aliens in the Arctic. A rather frustrated Ben Grimm says that if he hears any "Klaatu Barada Nikto!", he's out of there (paraphrased).
 * In one Don Rosa comic Donald Duck greets an alien with this phrase, accompanied by the Vulcan salute (or as close to it as he can get with only four fingers).

Film
"Ash: Klaatu...barada...niCOUGHtCOUGH!"
 * In Army of Darkness, Ash needed to say these three words to shut down a rampage too.
 * And of course when it came time to say them, he forgot what the third word was.
 * Twice.


 * Some of the subsequent allusions to this phrase (including some listed on this page) refer to Army of Darkness, which has overshadowed The Day the Earth Stood Still to some extent.
 * Extremely obvious in Germany. In Army of Darkness's German dub version, the line was "Klaatu Verata Nikto", so every German dub afterwards that considered AoD to be the origin of the reference will have the "Verata" line.
 * In Galaxy Quest, the Thermians come from the Klaatu nebula.
 * In Star Wars, Klaatu (of the species Nikto) and Barada (of the species Klatoonian) were two of Jabba's guards.
 * In the Robin Williams movie Toys.
 * In Tron, a plaque that reads "Gort, Klaatu Barada Nikto" can be seen on the wall of Alan Bradley's cubicle. Oddly appropriate for a programmer on a system like ENCOM's grid.

Literature

 * In the short story A Sound of Blunder, "Klaatu Barada Nicto" was the phrase spoken to the Captain Ersatz of the Necronomicon in order to travel through time. Saying it backwards brings one back to our time.
 * In one of the volumes of Animorphs Ax is forced to demorph in front of a human (to his andalite form) when his morph is poisoned. Marco, disguised in morph and speaking for Ax using thought-speak, attempts to convince the human that Ax is friendly using this phrase.
 * In the Star Wars Expanded Universe, the Nikto are a species of reptilian slaves, while Barada and Klaatu are two of Jabba the Hutt's lackeys.
 * In the Stephen King novel, The Tommyknockers, a young reporter, John Leandro, is convinced that something is wrong in a small town called Haven. His collegue, David Bright mocks him from it, saying that it's must be "green men from space" and quotes the phrase. (The town is actually controlled by aliens).

Live Action TV

 * Farscape
 * Hercules: The Legendary Journeys
 * Honey I Shrunk the Kids
 * The phrase appeared in an episode of The Monkees, when Mickey Dolenz is replaced by an alien-controlled robot.
 * One of the three passwords in the Room of the Secret Password in Legends of the Hidden Temple.
 * In The Rockford Files, Rockford said it to a rather large chunk of muscle.
 * Wings "Black Eye Affair"

Music

 * The band Klaatu is named after the same character.
 * Ringo Starr's solo album Goodnight Vienna uses a still from The Day The Earth Stood Still as its cover art, with Ringo's head replacing Klaatu's.

Theatre

 * The play The Foreigner references this. The main character, a science-fiction magazine editor, ends up scaring off the local KKK with a string of frightening-sounding nonsense, including this line.

Video Games

 * Reunion has a scientist named Klaatoo and a planet named after him with moons called Barada and Nikto.
 * The Lost Vikings 2; in the medieval levels, the teleportation spell is always "Klaatu, barada, something". Needless to say they don't work as desired.
 * Myth II: Soulblighter
 * robotfindskitten
 * In RuneScape, the magic words "Klaatu Barada Nikto" spoken by a certain character trigger a spell that teleports you a place where you can mine rune essence.
 * In Sacrifice, "klaatu", "barada", and "nikto" are three of the magic words that are combined to form various magical incantations; though not necessarily all three together or in order.
 * Mysterio's first appearance in Spider-Man 2, The Game Of The Movie, has him posing as an alien invader, and says this, as well as "All Your Base Are Belong to Us."
 * It's worth nothing that Bruce Campbell was the game's narrator. (Mysterio was voiced by James Arnold Taylor.)
 * In World of Warcraft, there are three NPCs named Klaatu, Barada and Nikto.
 * Spyro 2 (Ripto's Rage/Gateway to Glimmer) references this, as a sage in one of the later levels claims that saying those words would bring Spyro to where he wanted to go at the start of the game. However, he couldn't quite remember the third word, so he dropped the matter.
 * There's a series of helms in Dragon Fable named after this.
 * Spike the Clown from Toonstruck says this in response to being told "I believe the spatula is mine!". Did we mention he's an insane clown?
 * In one mission in the RTS Myth: The Fallen Lords, a barbarian is sent to say the magic phrase that will awaken Myrdred the Deceiver. Subverted when, even though the barbarian says something like "Clambake Baraka Nictuu", it works anyway... Myrdred wakes up from his thousand-year-sleep, says "close enough", and teleports himself and your troops out of the area.
 * When Globox is trying to open the doors in Rayman 3, he can be heard calling out this phrase, among others.
 * In Robot Odyssey, it pops up after solving the final puzzle on the city level.
 * In the "Ebil Dread" adventure from the Adventure Quest Worlds 2nd Birthday Event, the horde of pink undead summoned up by Beleen can only be destroyed by assembling the George Lowe-onomicon and speaking the magic words. As the adventure in question is a Shout-Out to the Evil Dead series and Army of Darkness in particular (including Artix replacing his possessed pink hand with a chainsaw), one can pretty much guess what those magic words are. And much like Ash, Artix...doesn't quite get that last word right. Poor guy.
 * The Peacekeeper in Sword of the Stars, in Pig Latin. It's been nicknamed "Ortgay" as a result.
 * Ragnarok Online the quest in the underworld Nifflheim (part of the very long "Sign" quest) where you speak the magic words "Klaatu Barada Nikto" to a ghost named "Ash", this is another Army of Darkness reference as the title character of that movie is Ash.
 * Uttered by the Advanced Magic Towers in Kingdom Rush.
