Sonic The Hedgehog is the more serious Sonic the Hedgehog cartoon adaptation made in the 90s, which inspired the Archie Comics series that's still ongoing (though the comic book came to the consumers first). It is very a sharp contrast to its contemporary and much more comedic weekday counterpart where Sonic was a drifter traveling the planet with Tails. Also known as SatAM (as in Saturday Morning, when it aired on the American ABC network), to distinguish it from AoSTH (which was in syndication on weekdays) and the games alike.
