Nicktoons Originals

Background
Nicktoons TV was launched by Nickelodeon in 2002 as a channel for their entire cartoon library, consisting mainly of archived ones (such as Ren and Stimpy, Doug, etc.). In 2003, the channel was rebranded as Nicktoons before being renamed to Nicktoons Network in 2005 and back to the former name in 2009.

1st Logo (2003-2005)
Logo: It utilizes the 2003 Nicktoons logo, saying "NICKTOONS", as it rotates in thin air like a boomerang until it splats on a pulsating gold light wall which fades to black.

Technique: CGI.

Music/Sounds: A splat sound.

Availability: Seen on later airings of the 2002 interstitial series Foul Facts.

2nd Logo (2004-2005)
Logo: Just the tail-end of the Nicktoons "Color Bars" ID, sped up, with the 2004 Nicktoons logo shining and sparkling.

Variant: An in-credit version was spotted on The Presentators, alongside the Aardman Animations and Nickelodeon logos.

Technique: CGI.

Music/Sounds: A harp glissando.

Availability: Seen on US airings of The Adventures of Napman. The in-credit combo is seen on The Presentators.

3rd Logo (September 23, 2005-February 13, 2008)
Logo: A car engine with the Nicktoons Network logo on the gates to the Nicktoons Studio (replacing the Nick footprint logo, especially the black footgate on the gate entrance is replaced by two flames) is shown zooming in and out as flames and smoke emit from the exhaust pipes over a cardboard coloured background with a moon and a cloud near the top right. A piece of paper with the Nicktoons Network logo slides in from the right as a crumpled ball of paper is thrown on top of it and unwraps, revealing the words "POWERED BY THE NICKTOONS STUDIO".

Technique: 2D animation by eXOpolis in Los Angeles, CA.

Music/Sounds: The sound of a roaring engine followed by 4 whooshing noises as the engine zooms in and out and sputtering sounds.

Availability: Was seen after other shows that reran on Nicktoons Network from 2005 to 2008. Replaced by the fifth logo.

4th Logo (February 25, 2006-September 2009)
Logo: We see a 3-D version of the Nicktoons Network logo, an orange wireframe globe with a "splat" on the right and "NICKTOONS NETWORK" below with "NICKTOONS" in Nick's corporate font, rapidly zooming out over a brown background textured to resemble crumpled paper. The text "ORIGINAL" appears below the logo and shines, as the logo revolves to face the right.

Trivia: If you look closely at the beginning, you can see the words "ANIMATION CAPITAL OF THE WORLD", a slogan of Nicktoons Network that used between 2005 and 2009.

Variants:
 * Sometimes the text reads "ORIGINAL PRODUCTION" and/or a copyright stamp appears below.
 * Some shows use a print logo on a background depending on the show (usually black, white, or in-credit), lacking the word "ORIGINAL".

Technique: CGI produced by eXOpolis in Los Angeles, CA.

Music/Sounds: A "whoosh" sound followed by a fast-tempo, percussion-heavy jingle. The print version uses the ending theme of the show.

Music/Sounds Trivia: The music is actually a bass-boosted snippet of "Rhythm Nation" by Janet Jackson.

Availability: It appeared on Nicktoons Network original shows, such as Kappa Mikey, The Secret Show, Edgar & Ellen, Nicktoons Network Animation Festival, Ricky Sprocket, Showbiz Boy, and Shorts in a Bunch. The "Original Production" variation appears on some episodes of Kappa Mikey and also on Three Delivery.

5th Logo (February 14, 2008-September 28, 2009)
Logo: On a white background, we see a bomb explode, causing many different pieces of Nicktoons characters (Guano's blue crystal from Kappa Mikey, Zim's mouth from Invader Zim, SpongeBob's eyes from SpongeBob SquarePants, etc.) to appear. The explosion reverses and turns back into the bomb, which looks like the Nicktoons Network "globe splat" logo. The "NICKTOONS NETWORK" text from the last logo in black is under the bomb.

Technique: 2D animation.

Music/Sounds: An explosion and various Nicktoons' dialogue in reverse, followed by a reverse sparking sound when the bomb reappears.

Availability: Was seen after other shows that reran on Nicktoons Network from February 14, 2008 to September 28, 2009.

6th Logo (September 28, 2009-October 22, 2014)
Logo: On a black background, we see a gray "t" surrounded by an orange glow suddenly zooming out and flipping around horizontally, as more letters surrounded by the orange glow fly out from behind it and everything comes to a halt like it's going in slow-motion. Then the letters quickly move back and rearrange themselves to read "nickToons" (in the post-2009 Nickelodeon font) and everything shakes when they arranged.

Trivia: The logo is based off the on-air look Nicktoons had from September 28, 2009 until May 5, 2014.

Variants:
 * The color of the word "Toons" as well as the background depends on the episode or show. For example, on at least one episode of Zevo-3, the word "Toons" was and the background was misty blue.
 * On  NFL Rush Zone  (which also uses the regular version of the logo), a print, in-credit version with "Toons" in blue.
 * There's a variant on some season 2 episodes of Speed Racer: The Next Generation where the logo (with "Toons" in blue) just appears on a black background and zooms in.
 * On  Grizzy Tales , the logo is next to the Grizzly TV, Honeycomb Animation, Elephant Productions and ITV Studios Global Entertainment logos.

Technique: CGI done by Roger in Los Angeles.

Music/Sounds: A whoosh, followed by an explosion sound, a loud electric guitar riff, a slamming sound and a cymbal crash.

Music/Sounds Variants:
 * The ending theme can be used sometimes.
 * On  Voltron Force , an eerie sound, followed by a drum beat with a loud, final electric guitar riff.

Availability: Seen on shows such as Zevo-3, Voltron Force, Dragon Ball Z Kai, NFL Rush Zone, and season 2 of Speed Racer: The Next Generation. Most of these shows have not aired since the mid-2010s, and very few of them have been digitally released since then.
