Great Cartoon along with the ABC version!
27 October 2004 | by (Kansas City, MO) – See all my reviews

Sonic Underground was a little bit like the SatAM series but not a whole lot because all the other freedom fighters from the SatAM are left out and so is Snively and the power rings. But at least this series still has the whole robotisizing thing. Another thing is that Sonic's Uncle Chuck was only in the first episode and they never see each other again. Another thing that was different was the way the SwatBots looked in this series. Sonic Underground is the 3rd Sonic cartoon that came out 2 years later after Sonic the Hedgehog (SatAM) was canceled again off of USA Network showing reruns.

In this cartoon, Sonic and his siblings Manic (Sonic's brother) and Sonia (Sonic's sister) are the hit rock 'n' roll band on Mobius called the Sonic Underground but in reality they are the children of the lost Queen Aleena, the queen of Mobius. Now Sonic, Manic and Sonia must fight Dr. Robotnik and save the planet Mobius and find their mother with the aid of their medallions. I missed Tails and the other freedom fighters from the 1993 ABC Series but at least I was glad that Knuckles the Echidna was in this series because I think Knuckles is one of my favorite characters in the whole Sonic the Hedgehog franchise along with Sonic! Plus I thought Manic and Cyrus were cool characters also! Especially Manic because Manic has that lay back and be cool sort of attitude plus I think he looks cool!

The only one thing I didn't like about this show was Gary Chalk doing the voice of Dr. Robotnik because he didn't make Dr. Robotnik sound scary and evil! I think Jim Cummings should have done this Sonic cartoon just like he did the voice of Dr. Robotnik from the ABC SatAM version. Or I think Mark Hamill would have done a good job at doing the voice of Dr. Robotnik since he is pretty good at doing creepy villain voices. But the only thing I liked about Dr. Robotnik in this series was that he looked exactly the same as he did in the SatAM Sonic cartoon! Also I liked Robotnik's bounty hunters, Sleet and Dingo. I liked Sleet better than Dingo because I thought Sleet was cool looking and I thought Maurice LaMarche was excellent to provide the voice of Sleet! Dingo I thought was stupid and funny. I didn't think Dingo was stupid as in I didn't like him he is just stupid as in not very smart as Sleet.

Why did this show have to last only one season? I think this show deserved more than one season! Just like the Sonic SatAM cartoon got to have more than one season! I first discovered this series when I was checking what was on TV the next day and I saw Sonic Underground on there and I asked myself, "Since when did Sonic come up with another cartoon?". At first I thought it would be a series that picked up where Sonic the Hedgehog (SatAM) left off but instead it sort of looked like a spin-off or a prequel. This series was pretty good along with Sonic the Hedgehog (SatAM) and Sonic X! This series also has great animation!
