Overlander

Overlanders are slightly mutated Humans from Mobius. Just like Mobians, the Overlanders were created by the Xorda's Gene Bombs. They tend to be an aggressive and barbaric species, and they're xenophobic towards Mobians.

Biology
The Overlanders look indistinguishable from humans, except they have hairs of different colours and possess 4 fingered hands and 4 toed feet instead of 5.

Culture and Society
Unlike humans, who are generally friendly towards and accepting of Mobians, Overlanders usually hold grudges, and in some cases feelings of outright speciesism, toward Mobians. This is partially due the Great War, though the Overlanders' distrust and dislike of the Mobians far predates this war. There are a few Overlanders who don't hate mobians in anyway, which include Nate Morgan, Maria Robotnik and Hope Kintobor.

Overlanders, partuculaly those in government or military careers (including the sciences) frequently sport an all-grey body suit. Overlander troops (also known as SWATbots) were typically seen wearing this attire during the Great War. Julian Kintobor was wearing one during his escape through the badlands, and Colin continued to wear one throughout and long after the Great War.

Overlanders do not share the Mobians' consideration for enviroment. While the Kingdom of Acorn deliberately remained a pre-industrial state to perserve the planet's enviroment and nature, the Overlanders pursued the use of fossil fuels, resulting in massive pollution in their cities.
