Biff Atlas

Biff Atlas, the Bodybuilder is an optional Portrait Ghost in Luigi's Mansion. He haunts the Rec Room in Luigi's Mansion, where he is found lifting weights. His first name is a pun on "biff", a slang term meaning "to hit". His last name is based on Atlas, a titan from Greek Mythology who was forced to hold up the sky. His portrait number in Professor E. Gadd's gallery is 16.

Luigi's Mansion
When Luigi enters the Rec Room, Biff is focused on lifting a barbell, choosing not to attack him. If Luigi wishes to capture Biff, he must first hit one of the three nearby punching bags toward Biff, while avoiding its backswing, which can hurt him. Doing this provokes Biff, who starts attacking Luigi by swinging his hands in rage. One of Biff's punches causes Luigi to lose twenty HP. Each time Luigi hits Biff with a punching bag, he becomes angrier and attacks quicker. After Biff is hit with punching bags three times, he collapses onto the floor, exposing his heart. This makes him vulnerable to the Poltergust 3000, allowing Luigi to suck him up. If Luigi fails to capture him, Biff returns to weightlifting and Luigi must hit him with another punching bag to resume capturing him. After Biff is captured, the Rec Room lights up, and a green treasure chest appears which contains money.

Physical appearance
Biff has turquoise skin with a blond flattop and green eyes. His head is rectangular, his chin has a small cleft, and his body is very muscular. He wears a red tank top, red wristbands with yellow stripes, a brown belt with a gold buckle, and magenta shorts that fit around his tail.

Trivia

 * A bust of Biff Atlas can be found in the The Artist's Studio.
 * Most of the time Biff Atlas is shown to be having a hard time lifting the barbell. If Luigi continues to leave him alone, he will eventually succeed in lifting it after a few attempts.
 * In his platinum frame in the remake, the background heavily features lilies, referencing his stated fondness for them.
