Eggman had sent Metal Sonic to attack Sonic, only to find Scourge at Freedom HQ, and decides to attack him instead. When Scourge commented that he was going to conquer Eggman's empire anyway, Eggman immediately began construction of Metal Scourge, remarkably finishing in a matter of minutes, presumably by repainting and redecorating a spare Metal Sonic.
By then, Sonic was on the scene, teaming up with Scourge to take down Metal Sonic. When Metal Scourge arrived, Scourge reluctantly called the Suppression Squad into the fray. Both mechs were destroyed by Boomer's sonic waves. He later makes a cameo appearance in one of later issues along with Metal Sonic.
