Mike (Orderly)

Mike first appeared in Rocksteady Game's Batman: Arkham Asylum in August 2009.

Biography
Mike was an orderly at Arkham Asylum, who was present during the Joker's takeover of the Asylum. He should not be confused with an Arkham security guard of the same name.

Arkham Asylum Incident
Mike was among the many orderlies and medical staff present during the Joker's takeover of Arkham Asylum. Mike was carrying out his regular duties in the Medical Facility's Sanatorium as Harley Quinn and an army of escaped Arkham inmates that were loosed from the Intensive Treatment Center in Arkham North invaded Arkham West. They overpowered the security guards outside the Medical Facility and invaded the Sanatorium through the Medical Foyer. The escaped Blackgate Prisoners, that were armed with guns that were taken from the security guards that they defeated in Arkham West, burst into the Sanatorium, under orders from the Joker to round up all the medical staff and the doctors in the building. The Joker told them: "Search every room, every corner, and every trashcan" to find everyone if necessary. Joker also told them that he did not want anyone, even the Arkham staff, to miss the "party" that he planned later that night. The armed prisoners located Mike and a second orderly in searching the Sanatorium, and held both orderlies at gunpoint. Mike was the first to be rounded up by the Joker's Henchmen. They also captured an unidentified doctor, and dragged Dr. Sarah Cassidy, another doctor, out into a large office space in front of the elevator that lead to the Secure Access Corridor.

While Dr. Cassidy cried quietly in a corner, the Joker's Henchmen took hold of Mike and strapped him into one of the two restraint chairs in the room to prevent escape. While Mike struggled against the chair's restraints, the henchmen strapped the second orderly into the second chair. Some of the Joker's henchmen proceeded to the Upper Corridor, where they shot several security guards and asylum orderlies before they went on to round up more medical staff, including doctors Stephen Kellerman, Adrian Chen, Penelope Young, and even guard Aaron Cash. Shortly after, Batman infiltrated the Medical Facility in search of Commissioner Gordon, who had been kidnapped by Harley. Prevented from entering the Medical Foyer by an electronic security barrier, Batman had entered the building through the roof by using Maintenance Access. He accessed the Sanatorium through the ventilation system, and finding the Sanatorium guarded by at least six armed prisoners. Batman defeated the henchmen, and then went to check on Mike and the other medical staff being held hostage. Batman found Mike and his fellow orderly strapped to the restraint chairs, and approached Dr. Cassidy to find out what had happened. Seeing that the Joker's men had been defeated, Mike tried to speak and wrestle free of his bonds but the chair's restraints prevented him from doing so. Dr. Cassidy explained that she, Mike, and the others had been carrying out their normal duties when suddenly armed thugs had burst into the Sanatorium and took them prisoner. Dr. Cassidy gave Batman the whereabouts of the other doctors and told him that she had heard gunshots from the Upper Corridor.

Batman investigated, and found at least three asylum guards and numerous orderlies shot on the floor. Batman instructed Dr. Cassidy and the others to await his return. Dr. Cassidy set to work freeing Mike from his chair: "Hold still, Mike. I'll get you free." After he rescued the other doctors, Batman returned to the Sanatorium with Cash and Dr. Young. Mike was stooping to examine the inert body of an inmate that Batman had knocked out earlier. Mike gathered with the three others to greet Batman as he returned. Dr. Young begged to be allowed to go to her office at the Arkham Mansion to retrieve her notes. Cash offered to escort her there. While the three argued, they were interrupted by the elevator coming from Secure Access. Dr. Cassidy reported that neither she, nor Mike, or any of the other two had called for it. Batman ordered Cassidy to go with Mike and the second orderly to the Patient Observation Room and barricade themselves inside. Batman then told Cash to escort Young to Arkham East to reach her office at the Arkham Mansion while he dealt with the armed goons who had arrived from the elevator.

Mike presumptuously remained there with Dr. Cassidy to wait out the remainder of the Joker's takeover of Arkham Asylum. Mike eventually survived the Joker's attack on Arkham and returned to his duties after the Joker's defeat, and helped treat the injured in the makeshift hospital that was set up in the Santorium. Mike also assisted in removing some of the remaining Arkham Lunatics that were loosed during the chaos to the Sanatorium, where they were placed in temporary cells due to the fact that most of the cell blocks had been damaged during the Joker's takeover.

After Arkham Asylum Incident
It is assumed that he along with the doctors in Patient Observation room survived the events and he returned to his usual duties at the asylum until it was closed down by Mayor Sharp.

Notes/Trivia

 * Notably, Mike was the only one of the masked orderlies in Batman: Arkham Asylum to be identified by name. The others remained more generic, and were credited only as Masked Orderlies #1, #2, and #3.
