Sonic the Hedgehog CDEdit

Metal Sonic debuted as a character in Sonic the Hedgehog CD for the Sega CD. He first appears at the start of Collision Chaos Zone 1, where he will kidnap Amy Rose in front of the player before escaping out of reach.

Metal Sonic is later encountered as the boss of Stardust Speedway Zone 3, where unlike the usual boss battle, he will challenge Sonic to a race to the finish. Metal Sonic cannot be touched by Sonic's attacks during this race, and he will destroy spikes upon contact. Metal Sonic will also periodically use one of two moves depending on Sonic's relative position to him. He will use the V. Maximum Overdrive Attack if Sonic is ahead of him, surrounding himself in harmful energy and gaining a large burst of speed which can only be outrun by using the Super Peel-Out. If Metal Sonic holds the lead then he will use the Ring Spark Field, giving him a harmful electrical field but also slowing him down. During the race, Dr. Eggman will be following behind the racers in an Egg Mobile which emits a high-powered laser from the bottom capable of killing the player in a single hit regardless of any protection he holds. Eggman will speed up as the race progresses, making it more difficult to avoid death if the player falls behind.

At the end of the race there is another door which will automatically close once one of the two racers enters. If Metal Sonic wins the race, he will taunt the player as Eggman inevitably catches up and kills the player. If Sonic wins, Metal Sonic will crash into the door and die, leaving Eggman to flee and allowing the player to free Amy Rose and complete the level.

In the Japanese and European versions of the game, the Bad Future music will play during the race regardless of the Future that the player is in. This is also the case for the 2011 remaster regardless of the soundtrack selected.

Boss InformationEdit


Sonic the Hedgehog Triple TroubleEdit

Metal Sonic reappears as a surprise boss in Sonic the Hedgehog Triple Trouble for the Sega Game Gear, this time fought in an actual battle in Atomic Destroyer Zone Act 2. Metal Sonic will ambush the player as the fly down a long corridor with the Rocket Shoes/Heli-Tails powerup and knock them to the ground before beginning the battle.

Metal Sonic has a simple attack pattern, flying from either end of the screen and diving at the player in an effort to deal contact damage. This provides the player with a chance to damage Metal Sonic. After Metal Sonic has been hit 4 times, he will use the V. Maximum Overdrive Attack to temporarily become invulnerable and dash across the bottom of the screen. After repeating this six times he will return to his regular attack pattern, and will switch between the two periodically. After being hit a further 8 times he will be critically damaged and slowly retreat off the screen, allowing the player to progress to the final stage.

Sonic Drift 2Edit

Metal Sonic appears as one of the seven playable characters in Sonic Drift 2, where he drives a blue racecar named the Blue Devil.

He has very high acceleration and the highest top speed in the game, but also has the worst handling. His special ability is the Super Dash, which gives him a brief burst of speed. It acts as a superior version of Sonic's Dash ability with greater power and acceleration, though it costs 3 Rings rather than the 2 that all other abilities cost.

Metal Sonic's race in the Final Chaos GP is against Sonic.

Sonic AdventureEdit

Metal Sonic makes a brief cameo in Sonic Adventure for the Sega Dreamcast, resting inside a stasis tube in the hub area of Final Egg alongside Silver Sonic II. Metal Sonic can also be seen in a flashback during Amy's story when she remembers him chasing after her and Sonic in Sonic CD, though the locations used resemble early versions of Windy Valley and Sky Chase.

Metal Sonic is also a hidden playable character in the remaster Sonic Adventure DX: Director's Cut, unlocked after collecting all of the Emblems. He plays identically to Sonic, even being able to drown in water, though he has different visual effects and sound effects.

Sonic Rivals 2Edit

Manual DescriptionEdit

A robotic version of Sonic the Hedgehog. Metal is looking forward to proving he is the REAL hedgehog and not that "loathsome copy" of Sonic. A pawn of Eggman, this speedy robot is forced to do his master's bidding.

Super Smash Bros for Nintendo 3DS/Wii UEdit


This robotic doppelganger was created by Dr. Eggman as a means to stop Sonic from interfering with his plans, but Metal Sonic's advanced AI chip gave him a mind of his own. At one point he even stole Dr. Eggman's identity and took over his fleet! Naturally, it fell to Sonic to put things right again.
