1up has a look back at the Metroid series
during the 20th anniversary of Metroid for the NES. From the article: "Metroid's gameplay isn't beloved exclusively. Fans love the series' heroine, Samus Aran. Samus is hard to define as a character, which adds to her appeal. In the scrolls of the Chozo, the avian race that raised her after she was orphaned, she's recorded as The Newborn, and the hope of their depleted race. To the Galactic Federation, she's the protector of the galaxy. To Space Pirates, she's the Huntress, or a handful of vulgar alien words. To gamers, Samus is mostly an enigma. Unlike other game heroines, she hasn't spread herself and her secrets everywhere like a high school senior of ill repute. Samus' motivations still command respect and a certain degree of awe."
