Some more information:

The central protagonists are Sonic the Hedgehog and Miles "Tails" Prower, while the main antagonists include Robotnik and his two hench-bots Scratch and Grounder (with a third robot, Coconuts, appearing on occasion).

There are many occasional minor characters and robots too, including Robotnik's dominating mother or Wes Weasley, a salesman and con-man, not dissimilar to Phil Silvers. The city has more non-human creatures, like anthropomorphic animals and robots than other projects. The planet, Mobius is more of a zany, colorful cartoon world in this version.
Sonic and Tails from the episode "Robotnik Jr."

Each episode featured the famous "Sonic Sez" segments where Sonic gave viewers advice on different topics, ranging from staying in school, not running away from home and not using guns to smoking, alcohol abuse, false advertising, sexual harassment, and even the dangers of riding in clothes dryers. Today, the segments, along with the entire show are often used in internet memes. Sonic Sez is commonly used in spoofs of the show on the internet.

Well, I'll leave you to enjoy the Adventures of Sonic the Hedgehog and don't forget to listen to what Sonic Sez ;) All this, and more at our TV-Shows Section.
