Dr. Eggman, "Cowbot"

Cowbot is a character that appears in the Sonic Boom television series. It is a cow-based robot created by Dr. Eggman to battle Team Sonic. It is essentially a walking nuclear bomb that can cause mass destruction when destroyed (provided it is loaded with Mootonium).

Concept and creation

According to Bill Freiberger, when they moved onward with the premise for the "Cowbot" episode, they thought it would be funny if the killing machine looked silly. They eventually thought of a cow which led to the cow tipping joke, thus leading to the decision to design Cowbot as a cow.[1]


Cowbot is designed after a bulky, non-anthropomorphic cow and is very large, over four times the size of Knuckles. It has a black and white body with a large front section and small grey front legs, and a smaller hind quarter with large white hind legs. Each leg has a red ring on their upper joint. It also has a long yellow and black-striped tail, a pink udder with six mammary glands and a thick grey neck with a cowbell around it. Its head is rectangular with a white upper left and lower right section, and it has two stubby yellow and black horns. When operating normally, its eyes glow blue, but when its stage two directive is activated, they glow red.


TV series

Season one


Cowbot going after Eggman.

Cowbot was created by Dr. Eggman and programed with the mission to destroy Sonic. Deployed by Eggman to eliminate Team Sonic, the team hardly took Cowbot seriously until Eggman told them that it would vaporize them if they destroyed it. Once Eggman left, Cowbot began attacking before turning its attention to Sonic alone, unaware it was being distracted while the rest tipped it over. Tails then reversed Cowbot's programing, making it seek out Eggman to destroy him instead. At the same time, Cowbot's stage two directive was activated, which rendered all the defenses at Eggman's lair useless.[2]

Over half a day later, Cowbot arrived at Eggman's lair, where Sonic, Tails and Eggman were ready for it. As Cowbot tried to get through the lair's force field, Sonic reached it with a catapult and poured melted marshmallows into it, this gunking up its machinery and shutting it down.[2] Restored some time afterwards, Cowbot was let out by the Lightning Bolt Society when they tried taking over Eggman's lair, but was soon after blown up by a stray missile launched by the same group.[3] Due to a lack of Mootonium, however, it did not create a violent explosion.[4]

Game appearances

Sonic Dash 2: Sonic Boom

In Sonic Dash 2: Sonic Boom, Cowbot makes a small appearance on the High Score menu and during gameplay.


Cowbot behaves much like an actual cow, showing an animalistic level of intelligence, a lack of defined personality and only speaks by mooing. It constantly shows a droopy and indifferent expression and is extremely easy-going to the point of obliviousness. Per its programming, Cowbot is single-minded and unquestionably dedicated to hunting down and destroying its targets, be it either Sonic or its own creator, Dr. Eggman.[2]

Powers and abilities

According to Dr. Eggman, Cowbot is the most destructive force in the universe. Though this statement is probably exaggerated, it still hints that Cowbot possesses great destructive potential. Similar to a tank, Cowbot boasts a lot of power and can fire powerful slimy cuds from its mouth as missiles, but it is incredibly slow and greatly lacks agility and balance. It is capable of flight by using rockets on its hooves, but flies so slow that it takes it half a day to travel a few miles. Like a real cow, it can also produce milk from its udder.[2]

Provided Cowbot is filled with Mootonium, a dangerous radioactive compound, it essentially becomes a walking nuclear bomb. Should Cowbot be destroyed, it can unleash an explosion which will vaporize anything within a twenty-mile radius.[2]
