Clucker (コケッコー,Kokekko?) is a Badnik that takes the form of a robotic chicken sitting in a turret created by Doctor Robotnik. Clucker has made its first appearance in Sonic the Hedgehog 2, as trying to defend Robotnik's air fortress by shooting different types of projectiles.
Sonic the Hedgehog 2
Making its first appearance in Sonic the Hedgehog 2, Clucker Badniks are the only enemies that are guarding Robotnik's Wing Fortress Zone. These Badniks are not first seen on their turrets until the player is moving more closely on them. When Clucker Badniks first pop out from their turret, they start a second later shooting egg-shaped bullets toward the player at a time. These Badniks shoot rotating eggs in a linear direction.
Usually there can be found one turret with Clucker Badnik, while sometimes there can also be two turrets with Badniks on each of them. The player can easily destroy Clucker Badniks by performing Spin Jump on them.
Sonic the Hedgehog Spinball
Two Clucker Badniks are featured in the 16-bit version of Sonic the Hedgehog Spinball, as they are seen in front of lonely Crawl at pinball table of the fourth bonus stage "Clucker's Defense". In this bonus stage, the player has to destroy Crawl from table by using three balls at the same time. In the game, turret cannons are replaced now with small bumpers, that bounces the pinballs easily.
While being impossible to hit Clucker Badniks in front, the player has to use pinballs to destroy badniks by hitting them from the side directions, as the one hit gives 1,000 points. The player also has to defeat Crawl from lateral sides multiple times until it lost its shield and with the last hit, it gets destroyed.
Sonic the Hedgehog Pocket Adventure
Clucker Badniks made another appearance in Sonic the Hedgehog Pocket Adventure, where these Badniks are again the only enemies seen this time at Aerobase Zone. While having same pattern and being featured on one or two turrets on the row, these Badniks pop out from turrets more faster now after the player is closer and right after starts shooting energy projectiles toward the player.
Sonic the Hedgehog 4: Episode II
Clucker Badniks made reappearance in Sonic the Hedgehog 4: Episode II, where these Badniks are featured at second and third acts of Sky Fortress Zone. While having upgrated designed models, their pattern is mostly same and linear from previous games. However these Badniks are now featured more frequently in the zone, while now shooting grey bullets from the cannon. Clucker Badniks are also seen shooting bullets from floating platforms or being featured on three or four turrets on the row at stair sections.

A Chicken type Badnik last seen defending "WING FORTRESS ZONE" in "Sonic 2". They will stand in Sonic and his friends' way, deployed everywhere within the incredibly enormous "Sky Fortress" as fixed batteries.
Sonic Lost World
Clucker Badniks reappear in both Wii U and Nintendo 3DS versions of Sonic Lost World. During the game, it turns out that Badniks, Cluckers included, got hijacked by the Deadly Six. Clucker Badniks appear on multiple Zones through the game and have a cartoon-like style from Sonic the Hedgehog 2. Regular types of Cluckers appear at Silent Forest Zone 1 and Lava Mountain Zone 3, which normally pop out of the turret and start shooting egg-shaped projectiles.
The Clucker Badniks also appear to be grinding on the Grind Rails on top of a minecart while shooting Sonic. In the Wii U version of Tropical Coast Zone 3, there are Clucker Badniks, which are controlling bulky, spider-looking vehicles, while regularly shooting projectiles from the turret. If the player tries to circulate from the top, the vehicle lands to above pathway with spike armor on the cockpit, while Clucker is hiding inside the vehicle. For all types of Cluckers, only a Homing Attack can defeat the Badniks.
Clucker, being as a Badnik based on the chicken, has a white body, while the rest of the body, which is never seen, is hidden at the turret. Clucker has red wattle / tail feathers, eyes with a strict stare, a small yellow beak, two antennae connected with grey buttons and two small wings used to control the turret cannon. The small turret, that is part Robotnik's flying fortress, has a small, grey cannon.
Clucker's appearance in Sonic the Hedgehog 4 is slightly detailed and has several color scheme changes. Otherwise the appearance has been mostly the same.
Clucker hides within a turret waiting for intruders. When Sonic or Tails come into its vicinity, it pops up from its turret and shoots cannonballs at them. Their cannons can only shoot forwards, but they can still take the player by surprise. After popping out turrets, these Badniks don't change their firing direction. The projectiles are seen to have rotating egg-shaped bullets, energy projectiles or grey bullets.
