Biff Atlas
Template:Portrait-infobox Biff Atlas, the Bodybuilder (Japanese: マッディー Maddī), is one of the many ghosts featured in Luigi's Mansion. His first name is a pun on "biff", which is slang meaning "to hit". His last name is based on Atlas, a titan from Greek Mythology who was forced to hold up the Sky.
When Luigi enters the Rec Room, Biff is focused on lifting a barbell, and does not attack Luigi. Luigi can either choose to provoke Biff to attack him, or just ignore Biff entirely, as Biff is one of the five optional gallery ghosts in Luigi's Mansion.
In order to provoke Biff, Luigi must smack one of the three nearby punching bags while avoiding its backswing, which can injure him. If aimed correctly, it hits Biff and causes him to attack Luigi by swinging his fists in a rage. One of Biff's punches causes Luigi to lose twenty HP. Luigi has to pound Biff two more times with a punching bag in order to expose Biff's heart. Before the third hit, Biff gets even angrier and starts whirling his arms. After his heart is exposed, Biff becomes vulnerable to the Poltergust 3000. If Luigi fails to catch him, Biff returns to weightlifting and Luigi must hit him with another punching bag to resume capturing him.
