Metal Sonichu
From CWCipedia
Metal Sonichu was a robot created by Dr. Eggman to destroy Sonichu and Sonic. Metal Sonichu attempted very valiantly to destory Sonichu but was tricked into smashing into the moon. He is still there to this day where he waits for his revenge.
In the next issue, Count Graduon will join forces with Metal Sonichu and crash the moon into CWCville just like with the ARK in Sonic Adventure 2. Will Chris be able to stop it? Find out soon!
