Slim Bankshot

Slim Bankshot, the Lonely Poolshark, is a portrait ghost that loves to shoot billiards. He was a legend in the competitive pool circuit, despite the fact that he never played a living soul. Slim spends his afterlife practicing alone in the Billiards Room of Luigi's Mansion. Capturing Slim Bankshot is optional in the original game, but required in the Hidden Mansion of the 3DS remake, due to Mario's Shoe being relocated to the Billiards Room. His portrait number in Professor E. Gadd's gallery is 17.

In When the Cold Breeze Blows Away, he will be respawned and joined with Undead Alliance by King Boo that he will become one parts of Portrait Ghosts.
