The Phantom Shinobi still retains the Heavy Shinobi's ninja aesthetic, with his biggest difference now being his missing appendages. Instead, the Phantom Shinobi possesses eight blades that surround him. The blades are green with yellow tips, with a gray line that connects the blades together onto Phantom Shinobi's body. The overall design of the Phantom Shinobi resembles that of a shuriken.
In Sonic Mania, during their climactic fight with the Phantom Egg, Sonic, Tails and Knuckles got transported to a different room where they fought the Heavy Shinobi-turned-Phantom Shinobi. Their fight was a brief one though, as Sonic and co. were returned to their fight with the Phantom Egg before the Phantom Shinobi managed to defeat them.
The Heavy Shinobi soon after became the Phantom Shinobi again. When Sonic, Tails, Knuckles, Mighty and Ray fought the Phantom Egg, the group of heroes got transported to a different room where they faced the Phantom Shinobi. Like before however, the Phantom Shinobi missed the chance to eliminate Sonic and co. when they got pulled back into the fight with the Phantom Egg.
Powers and abilities
The Phantom Shinobi is capable of flight and possesses eight blades that form a shuriken around his body. By spinning around, the Phantom Shinobi turns into a giant lethal sawblade. He can also extend his blades over a wider range.
The Phantom Shinobi segment is the second section the player will be transported to. The Phantom Shinobi will bounce or charge across the room. While on the left side or right side of the room, he will fire his outer spiked segments off temporarily before summoning them back to himself. When doing this, he will go to the left side of the room first before heading to the right side of the room.
