The Prior reported to Blackout that the Conduit had been repaired after Naju had messed with it. Blackout then turned him into a "Prior", making him the height of an average Toa, changing his colours to black and silver, and giving him fire and telekinesis powers.
He was then teleported to a planet where Ynot was fighting Ynohtna, and set Ka-Oni-Santsu on fire. Ynot demanded to know who the Prior was, and the Prior responded by making Ka-Oni-Santsu fly out of Ynot's hand and telling him he was an emissary of Blackout. Ynot then retrieved his weapon and correctly guessed that the Prior was a messenger. The Prior then continued to play tug-of-war with Ka-Oni-Santsu as the rope while telling Ynot he should rejoin the Brotherhood of Makuta. He then re-sheathed Ka-Oni-Santsu, and disappeared. Blackout then killed him.
