"Roboticizing" and "Roboticized" redirects here. For other uses of the term, see Roboticization (disambiguation).

Robodillos, subjects who have undergone roboticization, from Sonic Chronicles: The Dark Brotherhood.

Roboticization (ロボット化 Robottoka?), also known as the Robotomy Treatment,[1] is a subject that appears in the Sonic the Hedgehog series. It is the process utilized by Dr. Eggman and his associates by which an organic creature is converted into a robotic being. This is accomplished by devices that are collectively known as Roboticizers.


Physically speaking, the process of roboticization converts living tissue into machinery: body parts are transformed into mechanical equivalents. Due to the transformation, roboticized subjects typically possess increased strength and other abilities.[2] Some roboticized subjects may also have been specially modified for combat, as in the case of what the Deadly Six intended to do with Tails. Roboticization can be carried out in different degrees: some subjects' whole body can be converted while others only have the process carried out on some parts of the body, making the subjects resemble cyborgs.[2][3] No means of reversing the roboticization effect have been revealed.

Roboticized subjects will lose their free will as a result of roboticization, becoming almost mindless automatons.[4] Whether it is possible to restore the roboticized subjects' mental capabilities while the bodies remain robotic is unknown.

Game appearance

Sonic Chronicles: The Dark Brotherhood

The roboticization procedure was first mentioned in Sonic Chronicles: The Dark Brotherhood. In this game, the Robodillo enemies are animals who have undergone roboticization.[5]

In Chapter 3, Tails noticed the Robodillos' condition after defeating a group of them in Mystic Ruins. Later after defeating another Robodillo group, Tails discovered an Eggman Device in the head of the leader which he deduced had roboticized the animals.[6]

Sonic Lost World

In Sonic Lost World, roboticization was not mentioned by name. The procedure itself was taught to the Deadly Six by Dr. Eggman.[7] Acknowledging Sonic's strength, the Deadly Six planned to enslave him with roboticization, but ended up attempting to perform it on Tails. However, Tails sabotaged his Roboticizer and donned a disguise dubbed "Robo Tails" that made him look roboticized to trick the Deadly Six.


  • The roboticization procedure originate from the Sonic-related medias in Western territories (North America is believed to be the region of origin, with other Westerners adopting it and altering its definition) where it is used as a significant plot point in various storylines. From Sonic Chronicles: The Dark Brotherhood, it was adapted into the games.
  • The roboticization process is based on the Sonic the Hedgehog video game series' original concept of roboticizing creatures, where an Animal is forcibly stored inside a robot shell and is used as its respective power supply. Unlike the extremely difficult process of de-roboticizing in other media, the restoration process for Animals in the games is done by merely breaking open the robot to free its captive within.
  • In the "Come Join the Eggman Empire!" propaganda video for Sonic Forces, Eggman details roboticization, which he refers to as his "all-inclusive Robotomy Treatment", as being a means to live in his empire. He notes that the "perks" to the treatment are being left unable to eat, sleep, or think again. He also implies that it is necessary to survive in the resulting air pollution within his empire.[1]
