The Mercado Hotel Security Guard worked at the Mercado Hotel.
Rowan North, while in possession of Kevin Beckman, reassembled the Barrier Compromising Master Machine in the basement of The Mercado Hotel. A security guard entered the room and yelled at Rowan to get his attention, asking him if he had everything under control. Rowan looked over his shoulder and growled at him with Kevin's eyes glowing green. The guard became sheepish and remembered he kept Visine in his desk drawer then left to go get it for him.
