Synopsis

Sonic, Tails, Princess Sally, and a band of freedom fighters battle to overthrow Dr. Robotnik, a despotic dictator who conquered their home planet Mobius years ago, and rules it as a polluted industrial dystopia.

The two cartoons, the syndicated Adventures of Sonic the Hedgehog (1993) and ABC's Sonic the Hedgehog (1993–1994), were produced by DIC Entertainment.

DIC also produced a Sonic Christmas special in 1996, and Sonic Underground in 1999, to promote Sonic Adventure.

Adventures of Sonic the Hedgehog comprises 65 episodes overseen by Ren & Stimpy director Kent Butterworth and features slapstick humor in the vein of Looney Tunes.

The 26-episode Sonic the Hedgehog (commonly called Sonic SatAM) features a bleak setting in which Eggman has conquered the world, while Sonic is a member of a resistance force that opposes him.

Sonic Underground was planned to last 65 episodes, but only 40 were produced.

In Japan, Sega and Sonic Team collaborated with Studio Pierrot to produce a two-part original video animation (OVA), Sonic the Hedgehog, released direct-to-video in Japan in 1996.
