Uncle Grimmly

Uncle Grimmly, Hermit of the Darkness is a fourty-five year old Portrait Ghost that loves mirrors. He appears in the game Luigi's Mansion.

Grimmly only appears after lightning strikes Luigi's Mansion, causing a power outage throughout the entire mansion. Grimmly locks the door of the previously accessible Breaker Room, preventing Luigi from reactivating the breakers and restoring power to the mansion. Shortly after the lighting strike, Luigi receives a phone call from Professor E. Gadd, who informs him that Uncle Grimmly holds the key and that he prefers to reside in rooms with mirrors.

Grimmly resides in the Wardrobe Room on the second floor, where he hovers in front of a mirror. Upon seeing Luigi, he attempts to scare him by lifting up his hand and wailing. During this movement, the ghost is vulnerable to Luigi's flashlight, allowing him to be sucked up by Poltergust 3000. After weakly struggling, Uncle Grimmly is eventually captured and drops the key to the Breaker Room.

According to Luigi's Game Boy Horror, Uncle Grimmly likes to keep to himself. This suits Grimmly's family just fine.

Trivia
He could possibly be Neville or Lydia's brother and could therefore be Chauncey, Henry and Orville's uncle.
