Sorry guys I should have said that I meant as a legitimate antagonist in the game. In all of those games you both mentioned, he appears only as a minor rival. My mistake!

(Just so you know I was asking about this because I'm currently developing the plot of a fan-fiction Sonic game series that is set years in the future of the current Sonic series; I needed to research if Metal Sonic has been completely destroyed yet so the fan series can explain how he returned as one of the antagonists. It will be put in the Sonic Fanon wiki some time next year.)
