Metal Sonic (メタルソニック Metaru Sonikku?) is the second boss of Stardust Speedway Zone and the twelfth overall boss of Sonic Mania and Sonic Mania Plus. He is fought at the end of Stardust Speedway Act 2. This boss battle was changed in an update for the original versions of Sonic Mania prior to the release of Sonic Mania Plus.

In Sonic Mania, Metal Sonic is fought with Sonic, Tails or Knuckles. In Sonic Mania Plus, he is fought with Sonic, Tails, Knuckles, Mighty or Ray.

Boss guide[]

Original[]

The battle begins after the player comes across and destroys a Metal Sonic hologram. The music stops and Animals rush on screen with nothing happening for a few seconds until Metal Sonic suddenly appears and begins the fight by initiating a race.

In the first part of the fight, Metal Sonic cannot be damaged. Instead, the player must make it to the arena while dodging Metal Sonic, who will be flying around trying to Spin Dash the player, fly into them using his Ring Spark Field, or use the V. Maximum Overdrive Attack to attack the player from behind.

When the player reaches the arena, Metal Sonic will interface with a gigantic Eggman-shaped generator to control it, thus commencing the second phase of the fight. The generator's "mouth" will then open as a Silver Sonic emerges from it. This Silver Sonic has two different attacks: it will either attempt to attack the player with a Spin Dash, or it swipe at the player using their extendable claw arms before dashing forward using their jet boots until they hit the edge of the screen. While the Silver Sonic can be disposed off with one hit like a normal Badnik, another one will spawn immediately after its destruction. Metal Sonic will also occasionally fire balls of electricity towards the player in an attempt to damage them. When the Silver Sonics rev up their Spin Dash, the player must perform a Spin Attack on them to make them bounce around the room and hit Metal Sonic.

Once four hits have been dealt to Metal Sonic, the generator will explode. Metal Sonic will also eject from the generator and the chase will resume. Along the way, Metal Sonic will attack like he did previously until the player reaches the top of Stardust Speedway where an Eggman statue awaits.

Once the player reaches the top, spiked blocks will drop in from above, creating a spike wall. Metal Sonic will then fly in and do his iconic taunt before beginning to hover on the ground and fly to the right as the spike wall starts to close in. From there, the player must outrun the spike wall and hit Metal Sonic after he attacks, which is when he is vulnerable. During this phase, Metal Sonic will utilize a bouncing Spin Jump, a Spin Dash attack or the V. Maximum Overdrive Attack if the player is not too far away from him but still ahead. If Metal Sonic is off-screen, he will activate his Ring Spark Field and fly ahead to launch multiple sparks at the player from the air (although he is still prone to doing this move if the player is behind him when he is about to pull off a attack).

Once Metal Sonic has been hit eight further times, he falls into the spike wall, destroying it, and the Capsule will float down from the sky, allowing the player to complete the Zone.

Current[]

The Metal Sonic boss battle received major changes with the release of the Version 1.04/RC 1.05.0713 update (which is present in the release of Sonic Mania Plus), making alterations to the second phase and changing the third phase entirely.

The opening and the chase sections (before and after the second phase) remain identical from the original version of the boss fight.

The second phase of the boss fight (where Metal Sonic uses the gigantic Eggman-shaped generator to spawn the Silver Sonic robots) has a few changes. Destroying the Silver Sonic robots now causes them to release four energy orbs travelling in a straight trajectory at different angles. While these energy orbs harm the player on contact, they can also be used to damage Metal Sonic. Hitting Metal Sonic this way deals half the damage compared to the original method (using the Spin Attack to rebound the Spin Dashing Silver Sonics to hit Metal Sonic). The number of hits on Metal Sonic required to complete this phase has been reduced from four hits in the original version to three hits in the current version (via using the Spin Attack), although it takes six hits from the energy orbs alone to complete this phase.

Once the player reaches the top, Metal Sonic will land on the platform, looking up at Dr. Eggman who has the Phantom Ruby. The doctor will then throw Metal the Ruby as the machine begins flashing. After a burst of light, Metal Sonic turns into Giga Metal. Giga Metal will trundle forward, chasing the player and smashing the floor behind him. If the player falls into the bottomless pit on the far left, they will lose a life. He has two attacks: dropping three small bombs which bounce towards the player and blasting a huge laser after charging for a brief period. Additionally, the player can also take damage if they touch his right arm swinging in the foreground though the arms do not swing while he is using either of his attacks. To damage Giga Metal, the player must hit the glass shell on his chest encasing the Phantom Ruby. When playing as Mighty, the player must be more cautious since if the player bounces on Giga Metal's right arm while jumping to hit him, Mighty may bounce to the left and can easily fall into the bottomless pit.

Upon defeating Metal Sonic by hitting the shell eight times, Metal Sonic glows as he explodes and eventually falls offscreen after returning to normal while dropping the Phantom Ruby on the ground. However, before the player's character can retrieve the gem, a Dango appears from offscreen and sends it flying away as the Capsule comes floating down from the sky. The player can then proceed to the Capsule and finish the Zone.

Trivia[]

  • The dock that Metal Sonic inserts himself into during the first phase is near identical to the one seen in his boss battle at World Entrance Level 1 in Knuckles' Chaotix.
  • The race sections in this boss battle are similar to original race against Metal Sonic.
  • The sound effects used for Metal Sonic are based on those heard in Sonic the Hedgehog CD, the game in which he debuted.
    • The sound effects used for the Silver Sonic are based on those heard in the 8-bit version of Sonic the Hedgehog 2, the game in which it debuted.
  • The boss music samples Metallic Madness, Stardust Speedway Bad Future and Final Fever from the JP version of Sonic the Hedgehog CD.
  • The projectile attack used by Metal Sonic during the second phase is very similar to one used by Super Mecha Sonic Mk. II in Sonic & Knuckles.
  • Dr. Eggman can be seen locating Metal Sonic in Press Garden Zone, the Zone before the current one, foreshadowing this boss battle.
  • During the first phase of the fight, two damaged Metal Sonics can be seen housed in green tubes at both ends of the screen. These are references to the Brotherhood of Metallix from Fleetway's Sonic the Comic.[1]
  • If the player collides with a Silver Sonic with enough speed (most easily achieved when using a Spin Dash while in the character's Super form), it will cause it to bounce off the top of the screen and a new Silver Sonic will be produced. However, the original Silver Sonic will eventually fall back down to the ground given enough time, making it possible to have multiple Silver Sonics on screen at the same time.
  • The generator seen in the first phase of the fight is very similar to the Robot Generator seen in Sonic the Hedgehog: The Movie.
  • This is the only boss battle in the game that provides a Star Post in the middle of the fight (though only in the current version of the fight).
  • During the boss encounter, using a Star Post (including those placed with Debug Mode) will form a Star Circle for a split second when touched, making it impossible to travel to a Bonus/Pinball Stage.
    • The player can however place and use a Star Post normally after defeating Giga Metal. If they use it to travel to a Bonus/Pinball Stage, upon finishing the stage, the player will still have to fight against Giga Metal again by moving to the right.

"Everything is canon: Metal Sonic's multitiered battle is a collection of cameos. The initial race and original final showdown are inspired by the Sonic CD encounter. The robot-spawning gauntlet and Encore DLC-altered final fight are homages to his fights in Knuckles' Chaotix. The Midbattle setting and multiple copies is a clear nod to the Brotherhood of Metallix, a group of villains from the British magazine Sonic the Comic."
