First seen in War Machine #18, destroyed in Tales of The Marvel Universe #2.

The Eidolon Warwear System (Mark and Model info unknown), often known as the alien armor, was a gift from unknown aliens who apparently wished to give us a defender for Earth's coming battle with Kang the Conquerer. The black, orange and green battlesuit was an organic partner that sensed Rhodey's heroic nature and drew him near so that it could organically bond with him. Skye, a female alien sent to tutor Rhodes, was killed before revealing the secrets of the armor, so we know very little of the suit's origin. However we do know this:

The Eidolon Empire seems to have died out a long time ago, but the armor was the pinnacle of their military technology, the ultimate war machine. Xenotechnology, the warwear system needs an organic partner to function. It bonds with the partner at the genetic level and can not be seperated from its host without killing the host. The resulting bodyglove-like suit has the ability to appear and disapear. In its dormant state the warwear leaves bodybands on the skin known as Mandalas, symbols that mark the partner forever as an Eidolon Warrior.

Beyond the armor itself, the linking has other benefits. The suit also has the power to heal its wearer's injuries. This regenerative process is good since any severe damage done to the suit results in actual physical pain and injury to the wearer; They are joined in all things. Furthermore, Jim Rhodes accquired some sort of time travel sickness during the Zeit Krieg storyline. The fatal condition was kept in stasis by the suit, leaving Rhodes unaffected, although the time disease did kill his good friend Sheva Joseph.

The warwear system itself was of an inditerminate age, although we know from War Machine's fight with the alien, Dirge, that the warwear systems can live for eons, even after their partner has passed on. When Rhodey linked to Dirge--a sort of Eidolon mindmeld--he also learned that the suit's themsleves recall the experiences and thoughts of past partners. One can only imagine the secrets Rhodes would've unlocked had his adventures continued in his own monthly title.

Known abilities of this suit: Through means of unknown Eidolon technology, the suit has the ability to create, to "grow," any weapon that the wearer can imagine. In addition, the armor posseses incredible speed and acceleration through unknown means of propulsion. The suit could also analyze chemical compounds through touch.

Armaments: Drone gun platforms that circle the right wrist, fully controlled by user. Shoulder deployed weapons platform that can grow whatever the user desires, i.e. concussion cannons, etc.

You know you're in trouble when: As the suit went into battle, it would begin to sing. As Rhodey throttled opponents, the suit blasted out fearsome, alien battle songs that recalled its glorious combat of day's past.
