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 its main colors are black and yellow, similar to Gemerl. It was made to awaken the Ifrit and raced Shadow, Metal Sonic, Silver or Espio (depending on the story mode). When either one reaches the Ifrit, Metal Sonic 3.0 tries to stop them from destroying the Ifrit and attacks them. Once the Ifrit is defeated, Metal Sonic 3.0 was either destroyed or trapped in the Ifrit's dimension. It is unknown whether or not 3.0 is a copy of Metal Sonic or Metal Sonic from the future.

Trivia

 * Despite being another inspiration from the image and DNA of the original Sonic, the two never actually fought or met.
 * Metal Sonic 3.0's colors, black with yellow stripes, are the same as Gemerl, Shadow Android (in multiplayer), and Eggman Nega's jacket, all three of whom are doppelgangers of other characters.
 * Despite being an upgraded version of Metal Sonic, he seems to be just as strong as him.
 * In Sonic Rivals 2, Metal Sonic 3.0's name and picture are displayed the same as Metal Sonic's, since he is just a palette swap of Metal Sonic.
 * A Mach outfit for Metal Sonic in Sonic Rivals 2 can be obtained to make him look like Metal Sonic 3.0 by successfully copying every other rival's signature move.
 * A Metal Sonic 3.0 action figure was proposed by Jazwares as a simple repaint of the already existing 3.75 inch Metal Sonic toy, similar to the Silver Sonic proposal. This idea was rejected by SEGA.
 * In Archie Sonic the Hedgehog and Sonic Universe comics Metal Sonic 3.0 has been re-named to "Shard".
