Protocol 11- Arkhamverse (Batman Arkham City)

 First Appearance: Batman Arkham City (2011)

Protocol 11 is a a fail safe that Hugo Strange built into Wonder Tower in the case of the tower being compromised and his plans failing. On the night of Protocol 10, Hugo Strange uses his last breath to trigger the explosive in the tower and kill both Batman and Ra's in the blast.

After Batman compromises Wonder Tower and Oracle shuts down Protocol 10, Ra's al Ghul arrives and stabs Hugo Strange through the chest. He tries to plead with Ra's that he just needs more time to defeat Batman, but Ra's tells him that he failed to see his “vision” through. Ra's turns away from both Batman and a dying Strange to bask in the destruction. Batman snarls that he will stop him, but Ra's merely laughs and says that he doubts it. In his last breath he remotely commands the tower with voice activation to activate Protocol 11, using the password “Wayne.”

Oracle warns Batman to get out of the tower and grabbing Ra's, dives from the tower as a five second countdown begins and the whole tower explodes.
