Metal Sonic 3.0

Metal Sonic 3.0 (メタルソニックver3.0) is Eggman Nega's copy of Metal Sonic that appeared in Sonic Rivals 2. The one difference between it and the original is that it's main colors are black and yellow, similar to Gemerl. It was made to awaken Ifrit and raced Shadow, Metal Sonic, Silver or Espio (depending on the story mode). When Shadow, Metal, Silver or Espio reach Ifrit, 3.0 tries to stop them from destroying Ifrit and attacks them. Once the Ifrit is defeated 3.0 was either destroyed or trapped in Ifrit's dimension.

Trivia
