House Party Protocol (Earth-199999)

The Iron Legion was formed by Iron Man's armor suits being controlled by J.A.R.V.I.S. and led by Stark himself.

The Iron Legion was summoned by Stark under the "House Party" protocol in order to help him battle the Extremis-enhanced soldiers assisting in Aldrich Killian's plot. Some suits were destroyed by Extremis soldiers, others by Killian, and the suits that survived the battle were subsequently destroyed by Stark's "Clean Slate Protocol," as Stark's way to show Pepper Potts that his suits were no longer his obsession nor his main priority.[1]
