The Sentinels are a variety of mutant-hunting robots appearing in Marvel: Ultimate Alliance 3: The Black Order.


The Sentinels were first created by Dr. Bolivar Trask, whose intention was to use them to save humanity from what he saw as an impending threat to the species' existence in the increasing number of mutants.


  • Sentinels are the enemy characters in Marvel Ultimate Alliance series' predecessor series, X-Men Legends, where they are major antagonists in the first game, and minor antagonists who are meant to be allies in the second game.
  • The Sentinels in Marvel Ultimate Alliance 3: The Black Order are voiced by Jim Ward, reprising his role from Wolverine & the X-Men and Marvel vs. Capcom 3: Fate of Two Worlds.
