Biff Atlas

"Look at this buffness! I'm huge! How'd you like to be my punching bag, weakling?"

- Biff Atlas

Biff Atlas, the Bodybuilder (Japanese: マッディー Maddī), is one of the many ghosts featured in Luigi's Mansion.

Biff is actually a pretty nice guy when not provoked and will simply ignore Luigi if he enters the Rec Room, where Biff resides lifting a barbell, and Luigi can do likewise. Biff also likes lilies because "they symbolize purity". Biff is also one of the five optional gallery ghosts in Luigi's Mansion.

In order to provoke Biff into attacking him, Luigi must smack one of the three nearby punching bags, avoiding its backswing, which can injure him. If aimed correctly, it will hit Biff and cause him to come at Luigi swinging his fists in a furious rage. One punch from the bodybuilder and the petrified plumber loses a whopping twenty HP. One hit with a punching bag still doesn't expose Biff's heart, so Luigi will have to pound Biff two more times with any punching bag. Before the third hit, he gets even angrier and starts whirling his arms like a runaway windmill. If Luigi smacked a bag but misses, he'd have to avoid both it and Atlas. After taking the hits, Biff will be knocked out and vulnerable to Luigi's attack. Unfortunately this attack wakes Biff up and causes him to pull against the Poltergust 3000. If Luigi fails to catch him on the first go Biff will return to weightlifting and Luigi must hit him with one more punching bag to resume capturing him.
