Cartoon Spin-Offs: The good, the bad and the WTF!?

Sonic the Hedgehog | 1993-94, 28 episodes

What’s it all about?
It’s the 33rd Century. Sonic and a band of outlaws called the Freedom Fighters (which from time to time include Tails, Knuckles and Amy Rose) are hiding out in the secret Knothole Village on planet Mobius after Dr Robotnik invades and conquers the city of Mobotropolis. Which, using all of his wit and evil genius, he renames Robotropolis. Sonic and the FF rebels frequently visit Robotropolis to steal mechanical bobbins or destroy the main robotising generator.

The show was distinctly - oooh - darker and dealt with more serious themes than the fast-moving mammal's other cartoon, Adventures of Sonic the Hedgehog, which aired in the same year. Storylines included abandonment - Tails heads off into the forest alone after no one would play with him; amnesia - Sonic loses his memory after getting hit by a powerful ray; and, still a burning issue, pollution - Dr. Robotnik plans to feed chemicals into the clouds to spread acid rain over the entire planet.
