The Tidal Tempest boss is a vehicle from the Sonic the Hedgehog series. It is the standard Egg Mobile built by Dr. Robotnik, who used it during the Little Planet incident.

The Tidal Tempest boss is a regular Egg Mobile. Oval in shape, it possesses its usual windshield, its blue seat, and its Dr. Robotnik symbol on its front part. It also has three thrusters on its bottom part.

Features and abilities

The Tidal Tempest boss is very fast, allowing it to move through a maze with ease. Its thrusters can also fire projectiles. In addition, while underwater, the vehicle can surround itself with a lot of Air Bubbles, creating a shield.


Sonic the Hedgehog CD

In Sonic the Hedgehog CD, Dr. Robotnik was wandering around Tidal Tempest until he was attacked by Sonic the Hedgehog. In an effort to destroy his enemy, the doctor dove under water, and surrounded himself with a shield of Air Bubbles. He tried to destroy Sonic underwater, but the hedgehog used the Air Bubbles to his own advantage and destroyed the vehicle.


The Tidal Tempest boss is the boss of Tidal Tempest in Sonic the Hedgehog CD, and the third boss overall in the game. While in the original version it is only faced by Sonic, the 2011 re-release makes it possible to face it with Tails.

Boss guide

Close to the end of the third Zone, Sonic will find Dr. Robotnik sitting in his hovering Egg Mobile, which will begin to fly into the depths of Tidal Tempest. The player must hit Robotnik four times before he departs into the sea. After this, the player will find the doctor floating in the water, surrounding himself with a shield of bubbles around him. Robotnik will partially dive towards the player while his bubble shield spins, and will fire a few projectiles at the ground. Sonic, however, has an advantage here, as the bubbles are the main oxygen supply to survive underwater, and once a bubble is gulped it will leave one less bubble around the Egg Mobile.

Once most or all of the bubbles are gulped, the player only needs to hit Robotnik once more to defeat him. The water level will then drop through the floor. Afterward, the player can proceed to the Capsule and end the Round.
