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 a thick gray upper half and black lower half. They also have large gray and orange round shoulders, thin arms and large blue and white hands with orange wristbands. 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. Lastly, they have a dome-shaped head with a wide smile, a pointy orange nose and blue eyes.
In gameplay, Egg Hammers are the slowest-moving enemies the player will encounter. They can only be damaged by attacks from the Power Type characters, although they can also be temporarily stunned with Thunder Shoot. The Egg Hammers have thirty health points and they will always drop one random Power Core not of the leader's type after they are destroyed.
When encountering the player's characters, the Egg Hammers will use two forms of attack. If the player nears them from the front, they will swing their hammers into the ground in front of them a couple of times. If the player is behind them or circling around them, however, they will begin spinning around in one spot with their hammer outstretched. The latter attack tends to make them dizzy and cause them to lose their balance, making them vulnerable to being knocked over with the Thunder Shoot or a Fire Dunk/Fire Launcher/Jump Fireball/Jump Fire Knock. They will eventually get back on their feet if not destroyed.
In gameplay, Egg Hammers will usually appear in rooms that seal off, where waves of enemies will appear to attack the player once they enter; 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.
Mario & Sonic at the Olympic Winter Games
In Mario & Sonic at the Olympic Winter Games, the Egg Hammer appears as an enemy. In this game, they are encountered during the Dream Alpine event and the Dream Snowboard Cross event. In gameplay, it is the strongest enemy in the game, but also the easiest to avoid. They mainly just stand still but will attack when a character gets too close. Hitting them will cause the player to fall down.
Sonic & Sega All-Stars Racing
In Sonic & Sega All-Stars Racing, the Egg Hammers (referred to here as Egg Pawn Giants) appear during the final mission in the game. To complete the mission, the player has to destroy the local Egg Hammer using power-ups from around Seaside Square.
In gameplay, the Egg Hammers' attack patterns and mechanics are the same as those in Sonic Rush. Like in Sonic Rush, they take three hits to be defeated, though 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 by any attack (aside from Team Blast). The player must find a way to knock the robot's helmet off before it will be susceptible to damage.
In the Sonic the Hedgehog comic series and its spin-offs 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.
