I tried to do a moveset with Dr. Eggman, but I couldn't. Eggman is a boss in the adventure mode though. Anyway, Metal Sonic isn't just a robot version of Sonic, he's very different.

Snake Codec Message
Otacon:"Watch out Snake, that's Metal Sonic."
Snake:"Great, a metal version of that blue guy? When will this hedgehog craze end?"
Otacon:"Sonic's arch nemesis, Dr. Eggman, created Metal Sonic to destroy the real Sonic. But Metal Sonic got a mind of his own. He can copy other people's data and use their moves against them, and he can turn into a huge, robotic monster."
Snake:"What kind of a name is 'Dr. Eggman'?"
Otacon:"His real name is Dr. Robotnik, I don't know why he calls himself Eggman."
Note:Get the hint, Sega. Change Eggman's name back to Robotnik.
Fighting against Metal Sonic
Metal Sonic is mainly a close range combatant, so keep your distance. If you're using a character with a neutral special move that leaves you vulnerable(such as Captain Falcon's Falcon Punch or Donkey Kong's Giant Punch), you can let Metal Sonic use Data Copy on it and it'll give him just one more attack that will leave him vulnerable.
