Astro Base Go!

Background
This is the vanity plate of The Venture Bros. creators Christopher McCulloch (credited as "Jackson Publick") and Eric "Doc" Hammer.

1st Logo (February 16, 2003-June 25, 2006)
Logo: On a black background, a general with a rod points to the heart of a space bot (named Soul-Bot) in front of a purple moon. As this happens, three colored circles zoom in from the top left corner, making the logo appear in different colors. Then the heart flashes and a spinning spiral pops out of it. Then the word "GO" amperes from the left as the spiral unfolds into a multicolored rectangle with the words "ASTRO-BASE" in purple. Then a circle zooms behind the logo in which the general and Soul-Bot disappear. Then a black circle zooms in making the moon white, and the background black. Then a flash of light goes around the logo making the words "GO" flash. Then the logo fades.

Trivia: Soul-Bot is also credited in The Venture Bros. as the voice of the Venture's personal robot H.E.L.P.eR.

Technique: A mixture of live-action and 2D animation.

Music/Sounds: Electronic beepers which fade out when the logo ends, and an odd robotic voice faintly saying "I love you" twice, though it could be interpreted as "I really like you, I love you".

Music/Sounds Variant: On the pilot for The Venture Bros., "The Terrible Secret of Turtle Bay", the electronic beepers are quieter.

Availability: Seen on the first season and the first episode of the second season of The Venture Bros.

2nd Logo (July 2-October 15, 2006)
Logo: There are actually 7 variants. It's very hard to describe the logo as every episode has its own animation, usually weird and/or pointless, and most of them featuring Soul-Bot, but almost every one of them has the name in the usual font.

Technique: Depends on the episode.

Music/Sounds: Same as the 1st logo. One episode had no beeping, but instead the voice saying "I love you".

Availability: Seen on the second season of The Venture Bros. beginning with the second episode.

3rd Logo (June 1, 2008-October 7, 2018)


Logo: We see the usual name zooming in, colored in yellow, and shining. The moon also zooms behind on a black background. Then a flying saucer appears from the moon and moves towards us, stopping under the name.

Technique: The shining of the logo, the moon zooming, and the flying saucer.

Music/Sounds: Same as the 1st logo, but later on, starting with the show's Halloween special "A Very Venture Halloween", a sword slashing sound is heard when the logo shines.

Availability: Seen on the remaining five seasons (which are seasons 3-7) of The Venture Bros.
