1st Logo (March 15, 1997-March 7, 1998)
Logo: We see the Sega logo fading in on a black background. the logo then flashes, warps and glitches in sudden cuts, one of them also being an electricity bolt, and then fades out.

Technique: 2D animation.

Music/Sounds: A tense synth pad drone with percussive echoes during the flashing.

Availability: Seen on the Neon Genesis Evangelion movies Evangelion: Death (True)² and The End of Evangelion, as well as their combined cut Revival of Evangelion.

Legacy: A very uncharacteristically dark and tense logo, but it nonetheless perfectly fits with the films it precedes.

2nd Logo (September 7, 1999)
Logo: We fade in to a white background. The SEGA logo with a trademark symbol fades in afterwards. Everything then fades out.

Technique: 2D animation.

Music/Sounds: None.

Availability: Seen on Sonic the Hedgehog: The Movie (the American release of the two-part Sonic the Hedgehog OVA).

3rd Logo (April 2019)
Logo: Transitioning from the Paramount logo, One of the rings from the 2019 Sonic variant transitions to the Sega logo zooming in a bit on a black background with blue dust. Electricity goes through the logo.

Technique: Simple but effective animation.

Music/Sounds: Electric sounds combined with the opening theme of the trailer.

Availability: Very rare. Only seen on the infamous first trailer for the 2020 movie Sonic the Hedgehog.

4th Logo (November 12, 2019-)
Logo: The scene opens with gameplay footage of the original Sonic the Hedgehog. The camera slowly starts zooming out, revealing squares containing footage from other Sega and Atlus produced and published/licensed games placed side by side. then, the camera zooms out quickly, revealing that the screens are forming a mosaic in the shape of the Sega logo on a black background. Finally, the logo flashes white, turning it with a white outline, making it the North American & European version of the logo. A "®" symbol appears next to it, and the byline "A SEGA SAMMY COMPANY" fades in below; both are in white.

Music/Sounds: The opening of the two Sonic films' score composed by Tom "Junkie XL" Holkenborg, listed in the soundtrack of the first film as "Meet Sonic (Before We Start I Gotta Tell You This)" (the second film uses a re-arranged version of the first part), which includes a majestic two-note melody alluding to the iconic "SEGAAAAAAA!" chant when the logo is complete. On Sonic the Hedgehog 2, the chorus comes in slightly faster and earlier.
 * On the sped up version, The sound when you lose all your rings in Sonic games is heard over part of the trailer's theme. It is followed by the sound when you collect rings in Sonic games.
 * On Sonic Prime, the Sonic the Hedgehog series' 20th anniversary sound (the 1-UP jingle from Sonic the Hedgehog (2006) and the ring sound) is used.

Legacy: A great tribute to Sega's history, and is sure to please many fans of the company. Hearing the Sega chant in a major motion picture is a definite bonus. Also, it's the first time a Sega logo has had a byline reflecting its parent company, Sega Sammy Holdings.
