Slim Bankshot, the Lonely Poolshark (Japanese: ボール・ロング Ball Long), 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.
When Luigi first encounters Slim Bankshot, the portrait ghost is playing 3-Ball, shooting billiard balls with his cue stick. Slim hits the balls so hard that they go flying off the table and bounce around the room, which causes five HP of damage if they hit Luigi. Each time they are hit, he goes around the pool table once before hitting the balls again. To make Bankshot vulnerable, Luigi has to suck up one of the flying billiard balls with the Poltergust 3000. The ball will then get stuck at the end of the vacuum, allowing Luigi to shoot the ball like a projectile at Slim Bankshot. As the balls hit Slim, he appears more and more fatigued when attempting to make a shot. After being hit three times, Slim will become limp and vulnerable and Luigi can capture the ghost with his Poltergust. If Bankshot manages to break free from Luigi's hold, the spirit will return to shooting pool and Luigi has to repeat the process.
A black-and-white picture of a person similar in appearance to Slim Bankshot can be found on the north wall of the Billiards Room, possibly depicting him when he was alive.
Slim has teal skin, glowing yellow eyes, and dark violet hair with a cowlick. His head is spherical, and he has a slender build. He wears a grey diamond-patterned vest over a white shirt with both sleeves rolled up. On his right hand, he has a gold ring with a red jewel.
