The Phantom Heavies[1] are a group that appear in the Sonic the Hedgehog series. They are modified versions of the Hard Boiled Heavies that engaged Sonic and his friends during their showdown with Dr. Eggman in the Titanic Monarch Zone.


Mania Mode

When Sonic, Tails and Knuckles got to the Titanic Monarch Zone, four of the Hard Boiled Heavies, now modified into Phantom Heavies, were able to take on the trio when Eggman sent them to their arenas using his Phantom Egg. Despite each of them getting a turn though, none of them were able to stop Sonic and co.

Upon reaching the Egg Reverie Zone, the Phantom King (a modified Heavy King) tried to steal the Phantom Ruby for himself, prompting Eggman to battle the Phantom King using his Klepto Mobile in an attempt to take the gemstone back. Sonic, having all seven of the Chaos Emeralds, transformed into Super Sonic and defeated both of the power-hungry monarchs however. With the Phantom King's defeat, the Phantom Heavies seemingly ceased to exist, but their ultimate fate remains unknown.

Encore Mode

The Phantom Magician reveals herself to be disguised as either Mighty the Armadillo or Ray the Flying Squirrel,(depends on who the player chooses) and steals the Phantom Ruby, then flies off. At the end of Angel Island. its revealed that the rest of the Phantom Heavies were somehow destroyed, (presumably from the destruction of the Titanic Monarch), and turned back into the Hard Boiled Heavies, making the Phantom Magician the last remaining Phantom Heavy. Its presumed that the Phantom Heavy survivor escaped and brought along her fallen teammates as well. The Phantom Magician gives the Phantom Ruby to the remains of the Heavy King, who activates and uses the Ruby to revive themselves and teleport into Green Hill Zone, then all scatter. Its unknown if the Phantom Magician ever reverted back into the Heavy Magician.

The Hard Boiled Heavies later turn back into the Phantom Heavies, with the exception of the Heavy King and possibly the Phantom Magician.
