Mr. Freeze
Finally, Mr. Freeze guides Batman along a hot path into a dining room, where Batman discovers that the villain has captured Robin, who followed Batman to the lair. Mr. Freeze serves them a warm dinner of roast beef and spinach, with baked Alaska for dessert. He even offers a cordial after the meal, but of course Batman does not touch a drop of alcohol. Batman pleads with Mr. Freeze to turn himself to get medical attention for condition, but Freeze refuses to believe that would be possible in prison and admits that he will have to murder Robin as well since the boy knows his whereabouts. Following the meal, Mr. Freeze attends to that by reducing the hot zone to a tiny area, his goal to freeze Batman and Robin, slowly in revenge for his skin condition. When he leaves room for only one person, Batman orders Robin to remain inside and then suddenly knocks Mr. Freeze to the ground. Batman took the precaution of wearing his "Special Super B Thermal underwear" as protection. His previous failures to subdue Dr. Schimmel were simply feints, to throw him off guard. Seizing his control box, Robin quickly warms the entire room and Mr. Freeze begins to suffocate from the heat.
