On the console games, the standard Egg Hammer looks similar to the Egg Pawn, but is about three times larger and much heavier. They possess purple armor and a round torso with a black lower half and a thick collar around their neck. They also have two red bolts on their underbelly and large cup-shaped shoulders with round red spikes (similar to knobs). They also possess large hands and feet, yet thin and gray upper arms and thighs, with red bands around their ankles and wrists, and purple armor around their forearms and lower legs. Their hands are mainly purple with gray fingers and their feet are shoe-like and purple with black soles. Lastly, they have dome-shaped heads with menacing green eyes, sharp red noses, and pointy teeth.
On the handheld games, the Egg Hammers possess their bulky build and colors, but are much smaller and slightly different. They possess a round torso with thick gray upper half and back lower half. They also have large gray and orange round shoulders, thin arms and large blue and white hands with orange wrist bands. They have no lower body to speak of, and instead have an orange, blue- and white striped spike on their pelvis with spikes around it. They finally have a dome-shaped head with a wide smile, a pointy orange nose and blue eyes.
The Egg Hammers first appeared in Sonic Heroes, where they can be encountered in Lost Jungle, Mystic Mansion, Robot Storm and Final Fortress. They carry large hammers that they use to attack the player. They are immune to most attacks from formations other than Power formation, but can be temporarily stunned by Thunder Shoot. The Egg Hammers have thirty health points and they will always drop one Power Core when destroyed.
The Egg Hammers attack either by slaming their hammer down or swinging their hammers and upper torsos in a few 360° circles. If the Egg Hammer chooses to swing their hammer, however, they will start to lose their balance once they are done swinging. At this point, the player can topple the Egg Hammer by attacking them, thus leaving them vulnerable to the player's attacks for a few moments.
In gameplay, Egg Hammers will usually appear in rooms that seal off, where waves of enemies will appear to attack the player once the player enters; the Egg Hammers are normally the last of these enemies to appear. They usually appear by themselves, although they will sometimes appear in pairs. For attack patterns, they move back and forth slowly and will attack the player with their hammer, which will cause damage should it hit, when the player approaches them. What makes the Egg Hammers dangerous in this game however, is that they require three hits to defeat (unlike other enemies) and do not flinch when struck, meaning the player can easily take damage if standing carelessly close to them after attacking them.
In the Nintendo DS version of Sonic Colors, the Egg Hammers look just like they did in Sonic Rush. In this game, they can be encountered in Sweet Mountain and Asteroid Coaster. Their attack patterns and mechanics are the same as in Sonic Rush. Like in Sonic Rush, they take three hits to be defeated, through they can also be taken out in one swoop using the Violet Void.
Powers and abilities
The Egg Hammers are quite physically strong, carrying their large hammers with just one hand and can create tremors by hammering into the ground. They are likewise highly durable, capable of withstanding a few head-on Boosts/Fire Boosts without flinching before being destroyed.
Each Egg Hammer carries a large purple, gray and black hammer with spikes. They use them for basic melee combat by bringing them down on foes or by swinging them around.
The Heavy-Egg Hammer is simply a larger and tougher version of the Egg Hammer. It is heavily armored and cannot be hurt from any attack (aside from Team Blast). The player must find a way to knock the robot's helmet off before it is susceptible to damage.
In the Sonic the Hedgehog comic series published by IDW Publishing, the Egg Hammers are Super Badniks created by Dr. Eggman. Their past is virtually identical to their game counterparts' up until Sonic Forces. After the war, the Egg Hammers began launching coordinated attacks on villages under a guiding force.
