Athena

Background
Athena Co. Ltd. was a Japanese game developer that was founded in July 1987 and went bankrupt and shut down on December 11, 2013.

1st logo (April-December 1996)
Logo: We see multiple black horizonal bars with a skewed image between them scroll up very quickly before slowing down, this undoing the skewing on the image and revealing that it's a corkboard on a white background and with the white and blue-shadowed text "PRESENTED BY" above a pinned piece of paper with Athena's logo on it. The scrolling slows down enough that the image and bars slightly scroll up slightly more before sinking down, stopping once the corkboard image is in view.

Variants: An early variant exists that simply has fading in from and to black. This is seen on Kaite tukutte Asoberu Dezaemon and may also be seen on emulated ROMs of the Dezaemon titles for the Satellaview.

FX/SFX: Sprite and fading animation.

Music/Sounds: A brief, loud static-like noise, similar to that of turning a CRT TV on, then a five-note guitar jingle.

Music/Sounds Variant: The aforementioned variant lacks the static-like sound. Availability: Seen on the Dezaemon titles released for the Satellaview, one example being Dezaemon BS Version - BS-X Shooting.

2nd logo (May 24, 1996-October 22, 1998)
Logo: We see, on a blue tile floor, a green ball with a light underneath it bounce from the left to the right three times, each bounce making part of Athena's logo rise up from the ground. The third bounce makes the ball launch high, and it promptly transforms into a green, round rabbit-like creature with long ears, blue eyes, a smiling mouth and a tan stomach, who then runs to the left of the logo. We then cut to a grey background, and the Athena logo zooms in and the rabbit holds their arms up and out. The background eventually fades to white.

Variants: FX/SFX: CGI animation.
 * On Dezaemon 2 and Crows: The Battle Action, the first part of the logo has multiple screens with the first part of the animation playing on them on top of a dark blue background. The rabbit also already has their arms in position.
 * On Joshikousei no Houkago... Pukunpa, we fade in to see the final part of the logo with the rabbit creature next to the Athena logo.
 * The logo used on Dezaemon 3D and the cancelled Dezaemon DD was simply Athena's logo on a white background, noticeably lacking the rabbit creature by its side.
 * The logo used for Super Bowling is very similar to this variant, though the logo fades in and out.

Music/Sounds: Cartoonish bouncing and twinkling noises followed by a rendition of the jingle from the previous logo.

Music/Sounds Variant: The shorter variants simply have the jingle. Availability: Seen on Dezaemon Plus and Dezaemon Kids!.
