Nathan, sometimes "Nate" (no last name known, no code name known) is one of the Stratosphere Siblings. He's a gadgeteer and devisor, like his twin brother, and seems to be having rather intense problems with his mother and younger sister. He is on the Class of 2009. The twins are known to be rather cavalier about the dangers inherent in their inventions, and therefore have to have them examined by their sister or Mr. Mahren before using them; that's the deal they made with their mother.
