Biff Atlas is a portrait ghost from the game Luigi's Mansion. He is a body-builder who loves muscles and lilies (because lilies symbolize purity).


To reveal Biff's heart, Luigi must smack a punching bag into Biff three times. When Biff gets hit, he becomes angry, and swings his fists wildly at Luigi, costing Luigi twenty life points if hit (1/5 of his total life), and forty life points in the hidden mansion. After the third punching bag attack, Biff will lie on the ground, dazed, with his heart revealed, leaving him vulnerable.
