Papa Nichols was a former World War II Sergeant who only appeared in "The Demonator". He is the 81-year-old father-in-law of Grammy Nichols and brother of Catherine Nichols. He is also the grandfather of Walter Nichols. During the episode "The Demonator", Drake and Josh were asked by their parents to watch over Papa Nichols while they were away (Papa Nichols was recovering from surgery at the time). However, instead, Drake and Josh went out to ride the new roller coaster: "The Demonator" and asked Craig and Eric to do the task for them. After having been persuaded, Craig and Eric agreed to watch him. While Drake, Josh and Megan were out, Craig and Eric were surprised to see Papa Nichols wake up. Having woken up, Papa Nichols believed he was still a soldier in World War II and that Craig and Eric were German soldiers that had captured him. This results in Papa Nichols constantly trying to hurt them in many ways, from throwing Craig out of a window to breaking Eric's cell phone by throwing it against a wall. At the end of the episode, he even confuses his grandson (Walter) for a Nazi soldier.
His most common phrase is "USA! USA! USA!", referring to his war days.
