- "Those who reject salvation embrace ignorance!"
- —Sean, while preparing to sacrifice a survivor
Sean Keanan is a psychopath appearing in Dead Rising and Dead Rising: Chop Till You Drop. He is the leader of the True Eye cult, obsessed with killing survivors in order to cleanse their "tainted" blood.
Frank first encountered Sean and the True Eye cult in Paradise Plaza while they are in the process of sacrificing a captive, Jennifer Gorman. When Sean noticed Frank taking pictures from afar, he declared him a heretic and ordered the cult members to kill him.
Sean was encountered again after Frank investigated the True Eye cult's hideout in Colby's Movieland. He came across Sean in Theater 4 with four captives tied up in the chairs and one hidden in a closet. After praying to a mannequin that had been impaled by a sword, Sean attacked Frank with a ceremonial sword.
After he was defeated, Sean knelt in front of the mannequin on the altar. He besought it to deliver him strength, but the mannequin toppled over and the sword impaled him through his right eye, killing him in a gruesome manner. Sean's death marked the final appearance of the True Eye cult, as the last of the cultists entered the room to avenge their leader, but Frank kills the remnants of the cult, finishing it off. Frank later retrieved the Movieland warehouse key from his body.
Next, he's at Wonderland Plaza from 2:07:00 to 3:00:00.
Then, he's at Theater 4 again carrying the Movieland Warehouse Key.
Sean wields a ceremonial sword as his weapon. Despite his age, he is one of the fastest enemies that Frank encounters.
Ceremonial Sword: Sean's main attack is by slashing at Frank with his ceremonial sword. He is capable of both a quick slash and an intricate attack that deals heavier damage.
Slide Kick: Sean can also attack Frank by sliding towards him and knocking Frank to the floor.
