During Operation Daybreak, A.I.M. deployed an Arc Armiger onto the S.H.I.E.L.D. Helicarrier. Knowing that this was an attempt to draw Tony Stark out of hiding, James Rhodes donned his War Machine armor and flew out to combat the Armiger. While Rhodes was able to defeat it, he could not destroy it due to the healing capabilities it had gained from being enhanced by P.R.O.T.E.A.N.. Stark planned to reprogram it and use it to his own ends.
When Stark and Rhodes led a S.H.I.E.L.D. attack on an A.I.M. base in Malaysia to prevent Kearson DeWitt and Ultimo from launching Project Greengrid, they unleashed the Arc Armiger to help them combat the A.I.M. forces. They then re-positioned the Greengrid relays and destroyed the central power structure. While this put an end to Project Greengrid, it the Arc Armiger was sucked in and destroyed.
