Mobians are creatures in various Sonic the Hedgehog continuities for which the main setting is the planet Mobius (from which the name mobian is derived). The precise definition of mobian varies by continuity, sometimes being a general term for residents of Mobius (and used in comparison to residents of other planets, including Earth where these are different), and sometimes referring specifically to the various species of anthropomorphic animals that are the main residents of Mobius (and thus used in comparison to other species, e.g. Humans).

Mobians are sapient, being capable of speech and generally (but not universally) bipedal and anthropomorphic. Even those based on animals typically have human-like hands with five fingers. Some may also have toes, although that is less common since, for instance, Mobians who are based on anthropomorphic ungulates have hooves for feet.


Mobians are usually one of the three main species featured in Sonic media, sometimes together with humans and animals.

Mobians are characterized by being anthropomorphic animals, possessing a wide range of aspects, species and colors. Physically they are characterized by a curious anatomy, as they have bodies of various shapes, some more muscular, others smaller, thinner, more corpulent etc. Most possess the quality of having thin legs and some possess human-like feet.

Mobians (especially males) do not usually wear a lot of clothes. The most common to see on them is the use of footwear that are usually of a large size. Others wear more complete clothing, such as dresses and jackets. It is also common for them to use accessories such as necklaces, bracelets, headphones and chains.

Mobians are usually no larger than a human, regardless of the animal or being they are inspired by, so it is not uncommon to see that they are able to move in any environment.

The most outstanding quality of mobians, is that many possess powers and abilities, both physical and magical, ranging from extreme speed to super strength.

Mobians in the various continuities

Adventures of Sonic the Hedgehog

In Adventures of Sonic the Hedgehog, the population of Mobius consists mainly of anthropomorphic animal mobians. However, humans feature regularly in the series in certain communities (e.g. Hill Top Village, Robotropolis).

Sonic Underground

Sonic Underground depicts a Mobius inhabited principally by non-human Mobians, although the variety of forms is greater than in previous series. While there are the usual anthropomorphic animals (based on dogs, horses, etc.) there are others that bear little resemblance to standard animals, having six arms, three legs, etc. Dr. Robotnik is the only human in the series.

Sonic the Comic

In Sonic the Comic, anthropomorphic animals comprise the majority of the population of Mobius, as well as some other planets (the Drakon Empire are mainly fish people) and dimensions (most notably the Special Zone). A large percentage of the population is humanoid without being based on a specific animal species (including Grimer), and there are a very small number of humans (including Dr. Kintobor/Dr. Robotnik and Zorabel).

Archie Comics

In the Archie Comics continuity, the term mobians (written with a lower-case 'm' unlike the term in other continuities) exclusively refers to the anthropomorphic animals that live on the main planet in the setting (called Mobius before the hard reboot caused by the Super Genesis Wave and simply Sonic's World thereafter) and similar dimensions. Other species in the setting have their own names (including humans and Overlanders). Sally Acorn also referred to the species as Mobo sapiens.

The pre-Super Genesis Wave continuity describes the origin of the mobians. In this continuity, Mobius is a futuristic Earth. After a human act of aggression towards an extraterrestrial emissary sometime in the 21st century, the alien Xorda bombarded the planet with powerful gene-bombs with the intention of eradicating all humanoid life on the planet. These explosives caused the native animals of the planet to mutate and rapidly evolve, growing larger and more intelligent. When the aliens return, they reveal that the new mobian species "contain a sizable percentage of human DNA". The humans that survived this attack had lightly-mutated descendants called Overlanders, that only have four fingers and toes, while their human ancestors have five. Doctor Eggman, Snively Robotnik, Gerald Robotnik, Maria Robotnik, Hope Kintobor, and Iron Queen are the only six Overlanders to have five fingers and toes instead of four. However, some humans survived and lived in isolation in Station Square for thousands of years. As such, humanity still maintains a presence on Mobius, albeit in much fewer numbers.

After Sonic & Mega Man: Worlds Collide, the planet setting of the series was renamed from Mobius to Sonic's World, and the term mobian was consequently dropped temporarily. It was later reestablished in the summer of 2016,[1] as a colloquial term to refer to the "anthropormorphic animals" that inhabit Sonic's World. Another change that the reboot event brought is that humans became regular inhabitants of Sonic's World, with little to no distinct differences between their game counterparts.

Post-Sonic Adventure games

Back during the Dreamcast era, SEGA planned to eliminate the North American and European concepts of Sonic. In the games post-Sonic Adventure, Sonic and his friends live on Earth. There is no official name to replace "mobians" so far.
