Following the awesome set photos posted by DCMarvelFreshman earlier today (find them HERE) we now seem to have confirmation that the threat The Avengers assemble against will indeed be of an extra teresstrial origin. The question now is, who exactly will it be?! Below, I've included a list of all the main Marvel Universe alien races, but feel free to let me know if you'd like to see anyone else added.
The Badoon
The Badoon are a reptilian alien species. They are notable for having a gender schism, resulting in two separate societies; the Brotherhood of Badoon (ruled by a 'Brother Royal') and the Sisterhood of Badoon (ruled by a Queen). The Badoon are older than the Kree and the Skrulls.
The Brood
The Brood aren't just savage, they're evil, intentionally enjoying the suffering they cause others, especially the terror their infection causes their hosts. They've been compared to "demons".
The Celestials
The Celestials are a star-faring race of humanoid aliens who possess untold cosmic power. Standing two thousand feet tall, the Celestials are clad in full body armor. No Earth being has ever seen what they look like beneath their armor or knows their origin.
The Dire Wraiths
Avoe is referred to as the Goddess and leader of the Dire Wraith tribe of Inhumans that are now inhabiting the Blue Area of the Moon. For years it was thought that the humans of Earth were the only species that the Kree, had performed their experiments on while seeking to create an army of living weapons.
The Kree
The Kree is an extraterrestrial humanoid race who have created a vast empire in the Greater Magellanic Cloud and have, on certain occasions, trafficked with the beings of Earth.
The Phalanx
The Technarchy is an extraterrestrial, sentient form of "techno-organic" life, resembling machinery in various ways. Because of their ability to absorb energy and mass from living beings, the Technarchy have a special safeguard in encoded in the techno-organic virus that they can transmit.
The Shi'ar
The Imperial Guard is a legion of super-powered champions from throughout the intergalactic Shi'ar Empire who act as enforcers of Imperial law. An elite corps of the Guard, dubbed Superguardians, protects the ruling emperor (majestor) or empress (majestrix) and carries out their personal directives.
The Skrulls
The Skrulls are an extraterrestrial humanoid race who have created a vast interstellar empire, the oldest known empire still in existence, within the Andromeda Galaxy.
