The Luigi's Mansion Series stars Luigi as a reluctant hero banishing ghosts from various mansions. The first Luigi's Mansion was released as a launch title for the Nintendo GameCube on November 2001. It was the first game officially created by Nintendo to feature Luigi in a starring role. It also introduced Professor E. Gadd, the quirky scientist, for the first time. Luigi's Mansion helped establish Luigi as an anxious character who is terrified of ghosts, though he would eventually overcome his fear and defeat the ghosts with the help of the trusty Poltergust 3000 given to him by Prof. E. Gadd.
Twelve years later a sequel, Luigi's Mansion: Dark Moon, was released on the Nintendo 3DS during The Year of Luigi celebration. The story concerns the destruction of the "Dark Moon"; a mystical object that, when whole, allows the ghosts of Evershade Valley to live in harmony. When the Dark Moon was destroyed it caused the ghosts become malicious and mischievous. Prof. E Gadd asks for Luigi's help, this time outfitting him with the Poltergeist 5000 and some new accessories: the Strobulb that blasts light to stun ghosts in place and a Dark-Light device meant to uncover objects and enemies that have become invisible.
