Based on a popular Sega game series, The Adventures of Sonic the Hedgehog follows the adventures of Sonic and his buddy Miles "Tails" Prower. Sonic is the fast-movin', impatient hedgehog. Tails is his curious little friend who is always eager to learn and tag along with his pal during quests. Dr. Ivo Robotnik (now known as Dr. Eggman), an evil mad scientist, is constantly scheming to find a way to destroy the blue Hedgehog . But it never works, because Sonic is always one step ahead of him!
After this show was introduced, Sonic the Hedgehog (also known as SatAM) came along. As they both aired during the same time era, people looked to this show for slapstick comedy, while SatAM was also there for people who desired a bit more focus on adventures. That show was based on Archie's Sonic-based comic strips, while this show was entirely accurate at the time. A few years after these two cartoons, DIC's final Sonic show - Sonic Underground - came to life. Altogether, Sonic and DIC stayed together from 1993 to 1999.
Sonic the Hedgehog - The adventurous hedgehog that is always ready to go on adventures. One of the first characters created for a video game on the primitive Sega Genesis system. As a mascot of Sega, Sonic runs extremely quick while rolled up in a ball. Although impatient still the leader of the heroes.
Miles "Tails" Prower - Sonic's best friend and all around good guy. Tails usually likes to go with Sonic on fun adventures. He is the engineer of the team, he loves to build and he is an expert on mechanics. He is able to fly while his tails are twirling quickly or he can use his powerful flying vehicle.
Dr. Ivo Robotnik - Robotnik is the evil villain in this cartoon, who is always trying to capture the blue blur, but it usually never works. He has many minions and uses them to battle and he only intervenes as a last resort. He owns a powerful flying vehicle and that unleashes tons of equipment such as a grappling hook.
Scratch - The leader of the sidekicks of Robotnik, obviously. The leader Scratch is a bit smarter than Grounder (though only by a short miss).
Grounder - One of the stupid sidekicks of Robotnik. As you will see he is a impatient, gullible and ignorant robot who never comes to any good to Robotnik - or even to his best (well, only) pal Scratch.
