LevelSonic ManiaPhantom Ruby
The twelfth and final zone of Sonic Mania (2017), Titanic Monarch raises the robot fortress of Eggman and the Hard-Boiled Heavies above a metropolis. The Phantom Ruby governs the whole level design here: vertical ascent, electric orbs that pull the hedgehog upwards, teleporters named Ruby Mists and gravity manipulations that amplify or shorten jumps. Act 1 pits you against the Crimson Eye, a nod to the Red Eye from Sonic & Knuckles, Act 2 against the Phantom Egg and its sixteen hits. The seven Emeralds open up Egg Reverie Zone, where the Heavy King betrays Eggman. Music by Tee Lopes.

🤖 the Hard-Boiled Heavies and their king.
The last zone of Sonic Mania
Titanic Monarch Zone is the 12th and final zone of Sonic Mania (2017), on the Little Planet. It is Eggman's tower-fortress, a gigantic mech erected above a metropolis, the lair of the doctor and the Hard-Boiled Heavies.

Gravity, illusions, and teleporters
The level fully utilizes the powers of the Phantom Ruby: vertical ascent, electric orbs that pull Sonic upwards, teleporters ("Ruby Mists"), and gravity manipulations that amplify or reduce jumps.

Two bosses specific to the zone. In Act 1, the Crimson Eye, a giant eye honoring the Red Eye from Sonic & Knuckles. In Act 2, the Phantom Egg: Eggman himself, powered by the Phantom Ruby, a prolonged battle (16 hits).
The true ending: Egg Reverie
Titanic Monarch hides the true ending. By completing the zone with Sonic and the 7 Chaos Emeralds, you access the Egg Reverie Zone. There, a plot twist: the Heavy King, leader of the Hard-Boiled Heavies, betrays Eggman, steals the Phantom Ruby from him, and becomes the Phantom King—whom Super Sonic must confront for the true conclusion.

Its reappearances
Titanic Monarch returns in Sonic Mania Plus (Encore mode), where it remains the ultimate zone. Its music, composed by Tee Lopes, is featured as "Built to Rule" (Act 1) and "Steel Cortex" (Act 2).
