The Moon Mech is a machine that first appeared in Sonic Lost World. It is a mech resembling the Moon which is used by Zazz during his various battles.
The Moon Mech is a spherical yellow mech that has a diameter slightly longer than Zazz's full height. It closely resembles the Moon, with rimmed and round openings in its surface resembling craters. It also has a face which includes two blue eyes with black sclera and a serrated mouth with a blue glow within. This face is capable of expressing emotions.
Features and abilities
On its own, the Moon Mech can float fast enough to keep up with Sonic the Hedgehog and shoot projectiles shaped like yellow five-pointed stars. It is also rather dense and/or durable, being able to create small tremors when impacting the ground. Since it has no interface, Zazz presumably controls the Moon Mech with his innate ability to manipulate magnetic fields.
The Moon Mech appears during the boss battles with Zazz. In the Wii U version, the Moon Mech first appears in Windy Hill Zone 2 where it shows up as the moon in the background before being summoned by Zazz for the boss battle. Here, Zazz will ride the Moon Mech in arches while shooting projectiles before pausing. In Windy Hill Zone 4, Zazz will run around with the Moon Mech while shooting its projectiles or throw it at Sonic, before reaching the end of the Zone where Zazz uses it as a bouncing wrecking ball or to roll over Sonic.
In the Nintendo 3DS version, the Moon Mech first appears along with Zazz at three different points in Windy Hill Zone 3. In these encounters, Zazz either sends the Moon Mech bouncing at Sonic, tries to roll him over with it, or throws it directly at him. While the Moon Mech can be avoided, it moves increasingly faster for each encounter. For the Windy Hill Boss, Zazz will chase Sonic down on the Moon Mech before trying to land it on him, eventually making it spew projectiles upon impact. Alternatively, Zazz will use it to roll over Sonic while standing on top of it.
In Sonic Dash, the Moon Mech returned as Zazz's vehicle for the boss battle encounters with him during the Stage. In gameplay, Zazz constantly rides the Moon Mech while having it shoot projectiles at the player from both the front and the rear until the player concludes the boss segment.
In Sonic Runners, the Moon Mech returned as an RC vehicle and an S Rare Power Type buddy which gives the player a chance of landing an additional attack on bosses.
During the "Zazz Raid Event", Zazz uses the Moon Mech for his boss battles. In gameplay, Zazz idly rides the Moon Mech as it moves towards the player while its projectiles come flying at the player from behind. The Moon Mech changes appearance in accordance with the type of boss battle as Zazz powers it up with Power Rings: Normal-type battles feature the regular Moon Mech, Rare-type battles feature a silver Moon Mech with purple eyes, and Super Rare-type battles feature a golden Moon Mech with red eyes. Also during the event, Omochao uses a broken Moon Mech Zazz left behind to demonstrate the restorative powers of Power Rings on machines.
