1st Logo
(1992-1996)

Logo: Over a white background, we see the Cartoon Network logo of the era without "STUDIOS" below. Underneath that is a byline stating "A Division of Hanna-Barbera Cartoons, Inc., A Turner Company".

FX: None, it's a still logo.

Music/Sounds: None.

Availability: Can be seen on first season Dexter's Lab episodes when reran on Boomerang. Also on other older Cartoon Network shows, like Tin Tin and The Real Adventures of Jonny Quest.

Scare Factor: None.



2nd Logo
(1996-1997)

Logo: We see the Cartoon Network logo of the era on a white screen, with an extra row stating "STUDIOS". Dexter bursts out of the logo in his robot, looking around afterwards. The standard H-B/Turner byline is below.

Variant: A longer version, seen only on one episode, has Dee Dee passing by, and touching the O's before Dexter appears, causing them to flip around briefly. Another variation has just the still logo without Dexter or any animation.

FX: Dexter bursting out.

Music/Sounds: Sound effects that correspond to the animation.

Availability: Due to only appearing on a few Dexter episodes, it is rarer than the first one. However, it shows up on Boomerang from time to time.

Scare Factor: Depending on the logo variant:

• None for the original variant.
• Low for the Dexter variant; you can be caught off-guard by Dexter's sudden appearance.

Final Note: In 1997, this unit was renamed shortly as Hanna-Barbera Studios, renaming back to its original name in 2001.



3rd Logo
(2001-)

Logo: Depends on the show, but the "standard" logo is as follows: Over a white background, a green laser passes over a blinking, grungy 1992 Cartoon Network logo, causing it to stop blinking. The same happens with the text "STUDIOS" in grunge style.

Custom Variants: All variations have a "sketched" look and often involve the logo opening and/or closing:

• Grim and Evil/The Grim Adventures of Billy and Mandy: Grim, with a smirk on his face, stands next to Billy and Mandy. He
  
  attempts to chop their heads off with his scythe, but fails because they hid in their shirts.
• Camp Lazlo: Lazlo blows a trumpet. Lumpus walks up with a large cork, and places it in the trumpet. Lazlo continues to blow on it.
• My Gym Partner's A Monkey: Jake and Adam swing on a vine (Adam, visibly uncomfortable, is being held by Jake). Jake
  swings off the screen, however Adam hits the edge of the logo.
• Samurai Jack: Jack slices the edges of the logo, causing it to close.
• Dexter's Laboratory: Dexter stands next to Dee Dee, who presses a button, causing Dexter to explode. After a flash of light, Dexter appears, scorched and visibly annoyed.
• Ben 10: Ben presses the Omnitrix, triggering a flash of light.
• Ben 10: Alien Force: We see a close-up of Ben's eyes. We then zoom out on him, as he presses the Omnitrix, causing a flash of light.
• Foster's Home For Imaginary Friends: Mac is tackled by Bloo. They both giggle.
• Class of 3000: A piano plays, and the characters are on it.
• Out of Jimmy's Head: Two of Jimmy's cartoon friends, Pickles and Prickles, hit each other with hammers.
• Powerpuff Girls: The girls each zoom in and beat up Mojo Jojo. This was also seen on The Powerpuff Girls Movie with a Time Warner byline.
• Chowder: Chowder walks by with a bag of food. He eats the "O" in "NETWORK". An apple falls out of the bag and replaces the "O".
• The Life and Times of Juniper Lee: TBA
• Megas XLR: TBA
• Squirrel Boy: TBA
• Johnny Bravo: Johnny shows off his poses, then kisses the screen. His lips get stuck in the logo.
• The Marvelous Misadventures of Flapjack: TBA

FX: Whatever the animation in the variation is. In the standard one, It's either a laser sound or the outro of the end theme (as in Whatever Happened to Robot Jones?).

Music/Sounds: The sound effects in the variation.

Music/Sound Variant: The first 2001 episode of Dexter's Laboratory (when former show writer Chris Savino took over production) had the custom Dexter logo, but with the audio from the 1997 Hanna-Barbera logo playing over it (with the weird laugh at the end). This was most likely due to an editing error.

Availability: The regular version appears on early episodes of The Life and Times of Juniper Lee and Ben 10, and the variations appear on their respective shows. Most of the variations during the Cartoon Cartoons era are rare and hard to find, though Dexter's variation survives on the short-lived revival of the show when it is reran on Boomerang. Johnny Bravo's variant appeared when Cartoon Network ran a mini-marathon of the show on 3/16/08.

Scare Factor: None to medium, depending on the version shown.
