I think that Metal Sonic should always appear as Eggman's silent dragon, who appears as the penultimate boss in each game, just before one final fight with Eggman. I don't even think he necessarily needs to be in game's plot; I remember the first time I played Sonic Triple Trouble, I was really surprised when Metal appeared out of no-where in the final level as a boss. I thought it was a really cool point in the game, shame his boss theme sucked.

I also think it would be cool if Metal Sonic was an unlockable skin for Sonic in all Sonic games, like in Adventure, but I think it should be easier to obtain than basically 100%-ing the game.
