Meter Droid

The Meter Droid is a character that appears in Sonic Mania. It is a robot created by Dr. Eggman that intercepted Sonic, Tails and Knuckles in Oil Ocean Zone.

Appearance
The Meter Droid is a humanoid robot based on the typical meterman. It possesses a spherical torso, shoulders and elbows, and a stubby but thick pole-like head. Also, instead of legs, it has a yellow propeller beneath its waist. Its torso, shoulders and elbows are colored yellow, and its torso is designed so it looks the Meter Droid wears black overalls. The Meter Droid also has white glove-like hands, a flat white mouth, cartoonish eyes with black pupils, and wears what looks like a yellow cap.

History
After getting about halfway through Oil Ocean Zone, Sonic, Tails and Knuckles came across the Meter Droid, who promptly fought them using its spanner and the Zone's steam vents. Although the trio beat this foe, the Meter Droid's destruction resulted in dangerous flumes getting released all over the Zone, making Sonic and his friends' trip much more dangerous.

Powers and abilities
Thanks to its propeller on its bottom, the Meter Droid is capable of flight. It is also proficient enough to effectively throw boomerangs.

Weapons
The Meter Droid wields a giant, gray adjustable spanner on its back which it throws like a boomerang in combat. Curiously enough, it flies and returns like an actual boomerang.

Battle
The Meter Droid is the mini-boss of Oil Ocean Zone and the sixteenth overall boss of Sonic Mania. It is fought with Sonic, Tails or Knuckles at the end of Oil Ocean Zone Act 1.

Boss guide
During the initial part of the battle, the Meter Droid will fly back and forth and toss the wrench at the playable characters (which eventually returns to it) before eventually going into the background and turning a release valve. When this happens, the green platforms below the character that cover the floor of the boss arena will become active and they must stand in the center platform or risk being shot up into the spikes that line the ceiling of the area. It is also wroth noting that the Meter Droid can only be damaged when it is in the foreground.

After landing six hits on the Meter Droid, this boss will be defeated, and the Act will be completed.

Trivia
