Nana is basically your stereotypical sweetheart grandmother type who keeps the living quarters tidy, bakes cookies, helps the heroes relax, and provides unjudgmental emotional support. She isn't afraid to scold those who get out of line though, so behave! She is the steward of the aircraft carrier's superhero-dedicated area, and also sometimes does maintenance repairs here and there, or paperwork. You also get the eerie sense that this woman has been around a looooong time. What's more, Nana has the strange ability to get more done in a day than time should allow. She can dedicate ten hours to five different tasks, and still somehow have time for ample relaxation and a full eight hours of sleep, all within a 24 hour time period. It defies all logic.
