Following the success of the DS and the lackluster sales of the GameCube, it was clear to Nintendo that systems with a broad appeal were key. Following this, they needed a home console successor that would usher in a revolution to gaming. This problem was solved by a name consisting of only one syllable: Wii.
According to interviews, Wii did not have interest in idols or even video games until she saw footage of a GameCube concert. The performance captivated her so much that she immediately broke into an obsessive fever, getting as many GameCube games and merchandise as possible. She even claims to have known every single GameCube game and song at one point. While most idol fans have no interest in pursuing a profession in the field, she was determined to become an idol herself, and so she did!
Wii is well known for her exaggerated choreography, characterized by her limbs moving in broad, graceful strokes that are easy to follow. This went hand-in-hand with the Wii Remote, an innovative new controller that used an infrared sensor to display a pointer on screen. This easy-to-access control scheme opened up gaming to a wider audience than ever before, and opened idol concerts to those that were not just otaku. While her stage effects were hardly much more advanced than GameCube's concerts, it was the mass appeal of her music and hardware that made Wii a raging success.
Going beyond the realm of gaming, Wii was privy to doing other promotional work for Nintendo. She appeared on TV stations frequently, doing weather and news reports, teaching photography, getting involved in elections, and even opening her own store. Her association with "Miis," Nintendo's avatar creation system, is one of her most iconic features. Some have noted her real life facial features have an uncanny resemblance to a Mii.
While Wii was aimed for a casual audience with best selling titles such as Wii Sports and Wii Fit, Nintendo did not neglect their core audience in mind. Massive hits such as Twilight Princess and Super Mario Galaxy are considered among the best of her work. She also did music for many third-party producers willing to get a piece of Nintendo, such as De Blob, Elebits, No More Heroes, Mad World and many more. Other Nintendo staples such as Super Smash Bros, Kirby, Donkey Kong and Fire Emblem made their home on the Wii as well.
Wii's personality has been described as perfectly plain and average, yet hosts an undeniable charm. Her graduation in 2013 made way to her successor, the Wii U. She was best friends with DS during her time at Nintendo, collaborating with her often. She also collaborated with GameCube on Twilight Princess. In retrospect, she considers that her obsession with GameCube was a bit parasocial, and getting the opportunity to work with her made her realize that. She is glad GameCube was tolerant about it, considering everything she had going on with Nintendo at the time.
