Phantom Egg

The Phantom Egg is the semifinal boss of Sonic Mania and the boss of Titanic Monarch Zone.

Appearance
The Phantom Egg is a battle suit used by Dr. Eggman. It is connected with tethers which electrify to all corners of the room. The Phantom Ruby is housed in the center of the suit.

Strategy
In the beginning of the battle, the Phantom Egg will form a shield which will block all attacks. Then it will start jumping around the room and then shot missiles at Sonic. After this, the shield will disappear but the tethers will electrify themselves. Soon after the Phantom Egg will be exposed for a short duration and the shield will activate shortly after. If enough hits are dealt to the machine, one of the four tethers will explode. After a while, two hands will appear and catch Sonic and will transport him to a short battle with one of the Hard-Boiled Heavies. After all tethers are broken, the player will get one of two endings-Sonic fighting in Egg Reverie Zone, or getting the Bad Ending.
