Adventures of Sonic the Hedgehog (produced concurrently with Sonic's other animated series Sonic the Hedgehog) put Sonic once again on the planet Mobius, trying to stay slightly more faithful to the source material than its Saturday morning counterpart, making Sonic and Tails the main characters. Robotnik, while a dictator in his own mind, is never shown as actually having any part of Mobius truly under his thumb, or any real power whatsoever. Instead, he tries time and time again to defeat Sonic the Hedgehog, using absurd and wild plots that are slanted more towards the viewer's amusement than anything.
Sonic's attitude in the series is deeply rooted in the concept of what was "hip" in the early to mid-90's, spouting off slang and catchphrases whenever possible. He also had a tendency to disguise himself to trick Robotnik and his minions Scratch and Grounder, allowing their plans blow up in their face as a result. Even though episodes such as the Chaos Emerald saga tried to raise the stakes, the characters in the series made sure to not take any event too seriously.

Produced under the supervision of Sonic Team, this two-part Japanese anime brought to life another version of Sonic the Hedgehog, also based on the games but once again being significantly different. Given no clear backstory, it is established that Sonic lives somewhere on South Island in the ruins of an airliner, and prefers to relax in this tropical locale then being needlessly bothered by other people. Sonic's personality leans more toward his Fleetway counterpart than his Adventures of Sonic the Hedgehog one. While he will still rush in to save his friends from certain danger and Dr. Eggman, there are times when he wishes to be left alone, and can suddenly snap at even his closest friends and allies.
