Hailing originally from Metropolis Zone, Shellcracker has returned to make Sonic lose as many rings as possible, if not finish him off entirely. Watch out as this Badnik's main weapon is a quick-moving claw that packs a serious punch!

— Profile, Sonic the Hedgehog 4: Episode I website[1]

The Shellcracker,[1][2] or Shellcraker[3][4] (カニパンチ[5] Kani Panchi?, lit. "Crab Punch"), is an enemy that appears the Sonic the Hedgehog series. It is a mass-produced, crab-based Badnik model created by Dr. Eggman.


Shellcrackers are based on red fiddler crabs. They each have a red and white carapace with a white abdomen, two pair of white legs and a pair of eyestalks with large yellow eyes. Shellcrackers also have two different-sized red claws. Their right claw is tremendous and has three spikes adorning the upper joint, while their left one is much smaller. For the original models, the left claw was connected to the Shellcrakers' body with four orbs.

The Shellcrackers' design in Sonic the Hedgehog 4: Episode I received a few changes changes. In this title, they have blue feet joints and the lower section of their claws are yellow on the outside and grey inside.

Game appearances

Sonic the Hedgehog 2 (16-bit)


The first appearance of this Badnik was in the 16-bit version of Sonic the Hedgehog 2, where it served as an enemy. This time around, this Badnik is referred to as Shellcraker[3] (カニパンチ[5] Kani Panchi?, lit. "Crab Punch"). In this game, the player encounters them in Metropolis Zone.

In gameplay, the Shellcrakers walk back and forth slowly, while also blocking the narrow paths to the High-speed elevator. They can attack with punches by extending their spiked claws out at the playable character in a straigth line when they get nearby, before retracting them. The player can destroy these Badniks by Spin Jumping on them from above or behind, but they have to be very precise with their aim; their large claws often block their hits from the front. Also, upon their destruction, they release an Animal.

Sonic the Hedgehog Pocket Adventure

In Sonic the Hedgehog Pocket Adventure, Shellcrackers appear in Gigantic Angel Zone. They behave and attack in the same manner as they did previously in Sonic the Hedgehog 2. Also, upon their destruction, they release an Animal.

Sonic the Hedgehog 4: Episode I

In Sonic the Hedgehog 4: Episode I, this Badnik is referred as the Shellcracker[1] and appears in Mad Gear Zone. Despite having an upgraded design, Shellcrackers behave like they did in Sonic the Hedgehog 2. The Shellcracker's claw attack is also now easier to predict, as it raises its left claw before thrusting its right one.

Powers and abilities

The Shellcrackers each possess a large pincher claw that packs a serious punch and can extend over a limited range.

In other media

Archie Comics

Shellcrackers, from Sonic the Hedgehog #229.

In the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics, the Shellcrackers were parts of Dr. Eggman's Badnik Horde who were guarding the Metropolis Zone during Operation: Clean Sweep.

After the Super Genesis Wave rebooted the timeline, Shellcrackers became nearly identical to their game counterparts. In this reality, they are Badniks under the command of the Metropolis Egg Army.


  • In Sonic the Hedgehog 2, Shellcraker can sometimes, for an odd reason, disappear from certain places where they should be in Metropolis Zone. This can also happen to the Slicer.
  • Like Slicers, the Sonic the Hedgehog 4 website points out their annoyance because of their placement and attack pattern in Sonic the Hedgehog 2.
