Awesome / Sonic Underground

  • Jaleel White voices all three hedgehogs, including Sonia, and gave them all distinct voices.
    • Not to mention the Urkel voice actually sounding appropriate for Sonia.
  • The hedgehogs wrecking Robotnik's Floating Fortress.
  • Sleet and Dingo steal a Chaos Emerald from Robotnik and plan to control Mobius with it.
  • The three-part story arcs were quite good; one featured Knuckles in a lead role.
  • Any time Aleena goes into Mama Bear mode.
  • In a call back to a Sonic SatAM plot, one episode has Robotnik challenge Sonic to a race. Sonia and Manic, figuring Sonic couldn't resist, show up to try and rescue him... except he knew it was a trap and didn't show, and they have to be rescued.
  • Bartleby Mink setting aside his aristocratic lifestyle to defy Robotnik near the end of the series.
  • Robotnik has an awesomely evil line in "Tangled Webs":
    Dr. Robotnik: When we find it, "Sanctuary" will become... "Cemetery!"
  • Dingo nearly destroys Mobius when powered by a Chaos Emerald.
  • The hedgehogs redeeming their evil counterparts in the mirror universe episode.
  • In "Haircraft in Space," the Do-Bot hypnotizes her customers into spilling their feelings about Robotnik, then forgetting they ever said it, and eventually goes on the run from Sleet and Dingo. The hedgehogs fight alongside her for a bit, then send her back to Robotnik... to hypnotize him into forgetting about the tape and his plans.
