Overlander

Overlanders are a species of slightly mutated descendants of Humans on the planet Mobius. They were a by-product of Xorda Gene Bombs during their attack on Earth that led to the mutation of the planet's inhabitants and the creation of Mobius in the first place. They are usually aggressive in nature and, due to past conflicts, some if not most have feelings of xenophobia towards Mobians. There are those who have been known to be non-aggressive with Mobians, such as Hope Kintobor and Nate Morgan. Some have even been willing to co-exist with them in the Zarvok Federations and other settlements with a Mobian populace.

Xorda Attack on Earth
Before Earth had became Mobius, the dominant species on the planet were Humans, also known as homo sapiens. During the 21st century, human scientist Ivan Kintobor had provoked an alien species known as the Xorda by capturing their emissary, and dissecting it for scientific study. In retaliation, the Xorda attacked the planet by bombarding it with Gene Bombs, which were intended to wipe out the human populace and preserve the rest of the planet's environment. Instead, most of the human population were devolved into Overlanders.

Culture
Due to similar physical appearances, Overlanders are commonly confused as humans. However, this is simply not the case, as both species have physical and mental differences. Unlike most humans, Overlanders have four fingers instead of five, and generally hold vast grudges. As a result, they have complete speciesism and prejudice towards Mobians, due to prior incidents and the Great War. At the time, common Overlander governments were Dictatorships.

Usually, Overlanders are seen wearing gray bodysuits whenever they work in a position of government or military, including scientists and even the common soldier. Julian Kintobor was seen wearing one when he was freed from prison, as well as Colin Kintobor, who continued to wear one even after the Great War had passed.

Overlanders usually don't share Mobian's consideration for the environment. In comparison, the Kingdom of Acorn deliberately kept itself in the pre-industrial state to preserve nature, while the Overlanders pursued the use of fossil fuels that resulted in massive pollution in their cities. Their technology had been on par with most human and Echidna settlements.
