Who's on First?

On Doom, Lotor has enlisted slaves to build his super power base with which he hopes to overthrow his father, King Zarkon. Work is over when a Robeast bursts on the scene and destroys the building. It seems Zarkon was wise to the plans and ordered Haggar to do the dirty work, though she hints that she would not have done so if Lotor had just included her in the plan from the start.
