|Appearances in other media|
The Caterkiller (ナール Nāru?, lit. "Nal") is a caterpillar-like Badnik model created by Dr. Robotnik, which makes its first appearance in the original Sonic the Hedgehog. Caterkiller seems to be a favorite design of Robotnik, since it is re-used in many other forms. For example, modifications of it, called the Sandworm and Catakiller, Jr., appeared in Sonic the Hedgehog 3 & Knuckles.
Sonic the Hedgehog (1991)
Caterkiller appears at Marble Zone and Scrap Brain Zone in the original 16-bit version of Sonic the Hedgehog. To defeat Caterkiller, the player must jump or roll into/onto its head with the Spin Attack, otherwise the player will take damage, and will scatter the Caterkiller's segments all over the place. If you destroy a Caterkiller in this way, an animal friend will not be freed.
In the 8-bit version of the game with same name Caterkillers only appear at Scrap Brain Zone. Caterkillers also have an identical pattern to the 16-bit counterpart, however even if the player manages to destroy these Badniks, it doesn't have animal friend inside of it, which is tradition in Master System and Game Gear titles.
Sonic 3D Blast
An unnamed caterpillar Badnik with the same appearance is seen in Sonic 3D Blast as it can be found at game's intro cutscene and Green Grove Zone Act 2, leaping between holes in the ground. As seeing spending its time underground, it will pop up from two dark pits which the Badnik jumps between. Attempting to defeat the Badnik with a spin jump while it's in the air may prove difficult, as mistiming the leap may make Sonic lose his rings (and Flickies) by connecting with the spiked tail. A more cunning method is to charge up a Spin Dash right on top of the hole; the robot will dive right into the spinning hedgehog and be destroyed, freeing one of Flickies of the Island.
The original Caterkiller doesn't make appearance until at Mountain Zone in the 2012 remake of Sonic Jump. Caterkillers act like they did in their first appearance, although they like to fall down to the lower platforms.
Sonic Lost World
Caterkiller appears in both Nintendo 3DS and Wii U versions of Sonic Lost World. During the game, it turns out that Badniks, including Caterkillers, got hijacked by the Deadly Six. These Badniks move on slowly to certain pattern like Snale Blasters and due to having segments, the player has to hit the head section with the Homing Attack, because hitting it to the other segment will make both get hit, as the Caterkiller will get destroyed while the player loses their shield, rings or even life in Nintendo 3DS version. They are seen in Windy Hill Zone 4 and Silent Forest Zone 3 in the Wii U version of the game.
Defeating Caterkiller is slightly different in both versions. In Wii U version, they are large and the player has to hit on to its head by doing Homing Attack or stomping. In Nintendo 3DS version, if the player pays attention to the by using a Somersault Kick on the Badnik, it will be easier to destroy Caterkiller without getting hit at the same time.
In the end of first act of Windy Hill for Nintendo 3DS, Sonic will also find himself running away from a much larger Caterkiller on the linear road with rock obstacles. In this appearance, Caterkiller do have more pink skin instead of purple and has eyelashes on her eyes, giving the Badnik a feminine appearance. After getting away from the Caterkiller, the player reaches the Capsule and completes the first act. These gigantic female Caterkillers are later seen in Sky Road Zone 1 in Wii U version. They are featured as moving obstacles during max-speed sections or larger enemies at the single planetoid section. Giant female Caterkillers burrow to the other side of the planetoid and will make shock waves, when their head collides to the ground. The player has to perform multiple hits to its head in order to defeat them to make a giant Spring appear.
The Caterkiller's model is based on a real-life caterpillar, both in its shape and the way it moves across the ground, stretching its four segmented body parts up and down to crawl along its programmed territory. It has two antennae located at the tip of its head.
An interesting feature of this Badnik is its ability to separate its four body parts if one of its 3 spiked segments are hit. As long as the head remains intact, this Badnik will continue to survive, albeit scattered throughout the area. Teeth can be seen on the front of the Caterkiller, but they have never been documented to have attacked with these. Standard colors for the Caterkiller model were a purple body shell with a gray underside, with a smattering of yellow for the antennae and spikes.
The Caterkiller's main attack pattern lies in its ability to only have one segment that can be destroyed without any injury to the attacker, making it more of a defensive Badnik than an offensive one. As stated in the Physical Appearance section above, not only will the attacker be hurt if they try to hurt the last three segments, but the segments will detach and scurry around the area, causing even more potential damage. Sonic had to be extremely careful when dispatching these enemies. The Caterkiller will also sometimes turn, but it is possible to hit without taking damage/losing a shield when Sonic is not invincible.

However, he let him go.
As Sonic decided to visit the Island of Misfit Badniks, Caterkiller and numerous other Badniks nabbed him. As usual Sonic quickly beat all Badniks, but as Pseudo-Sonic arrives, the duel between them makes the island sink down. Caterkiller as leader, seeing Sonic going away, makes a promise that they will return. Badniks with Caterkiller return with revenge plan with enlarging Pseudo-Sonic, but got interrupted by the Forty Fathom Freedom Fighters. Caterkiller led the last wave of Badniks which includes Jaws, Bat Brain and Buzz Bomber. However as wrapping himself around Ray, it gets knocked out by Pseudo-Sonic and all of them got crushed by Big Fluke into a cube.
In issue 226 of Genesis arc., Caterkiller tries to attack Sally in Marble Zone, but got captured and destroyed by Rotor. Other Caterkillers later got destroyed by Sonic and Buzz Bomber. At another place and another time in issue 242, two Caterkillers attack to Sonic, Shadow and Tails in the Olympic stadium. These models look a little bit different and bigger looking, as these models have no feelers, but they have white blank eyes and a cannon, which sucked Tails and Shadow in. Sonic manages to destroy one, but another one manages to get away and off-screen Eggman captured them with an Egg Capsule.
