Not to be confused with the Ultra Freeze-O-Matic from the Adventures of Sonic the Hedgehog.

Doctor Robotnik’s Freeze-O-Matic[1] (フリーザーモービル Furīzā Mōbiru?, lit. "Freezer Mobile"), or just Freeze-O-Matic for short,[1] is a boss from Sonic the Hedgehog 3. The player will encounter it at the end of Icecap Zone Act 2. The Freeze-O-Matic takes eight hits to defeat, and the battle against it takes place within a wide arena.

The Freeze-O-Matic is created and piloted by Dr. Robotnik, and possesses extra armor and refrigeration tubes. Below the Freeze-O-Matic is a radiator tube, which has a small platform with spikes on the bottom. Both the radiator tube and platform can blow cold blasts of freezing air that can freeze the player in a block of ice.


After arriving in the battle area, Dr. Robotnik extends the radiator tube and starts hovering back and forth in the arena. During the battle, the Freeze-O-Matic fires a cold blast in one of three directions: either left or right from the weapon extended out of the machine's bottom, or down from the bottom of the Freeze-O-Matic itself. For a short time after the fight begins, these blasts will occur in a regular pattern from left-center-right-center etc, although they will later come in a random order. In some cases, Dr. Robotnik will even fire a cold blast downwards twice in succession. If the player gets into the firing line, the playable character will be frozen, similar to the snowblowers in IceCap Zone. If the player has Tails as their partner, he can release Sonic from the ice prison regularly before he gets damaged.

After landing six hits on the Freeze-O-Matic, the main radiator tube of the Freeze-O-Matic will break up. Two more hits are required to defeat it, most easily done from the front. The only real threat to the player at this point is the icy gas leaking out of the back of the damaged Freeze-O-Matic, which still has the same effect as before. After two hits, Robotnik will fly away while the mobile is destroyed.

When playing as Knuckles in Sonic the Hedgehog 3 & Knuckles, EggRobo will retract the platform just after firing the icy gas to the sides, making the jumps very hard to execute. Super Sonic can easily destroy the Freeze-O-Matic thanks to his increased jump height (and his invincibility), but when playing as Tails (who has no Super State normally available) the boss must be defeated in a more conventional way.


  • The English name is based on "Egg-O-Matic", which itself is an early English title for the Egg Mobile.
