The Ice Climbers Popo and Nana are Wario's two lackeys. They follow Wario around as protection for his deals. When Wario was made an honorary deputy for the Mushroom Kingdom Police Department, they were used to interrogate prisoners. During the Battle of The Ivory Towers, the Ice Climbers sided with Wario and the Koopas. They got in a fight with Fox and Marth, during which Nana knocked out Popo and took his hammer. In the fight she was knocked unconscious by Marth. They ultimately survived the war, but what they did with their lives from then on is unknown..
