Luigi is a boss in Slender Fortress.
Luigi is a partner for Luigi Doll that seeks for people. He is shaped like Luigi, but has no eyes, and has cracks all over his body, and floats in a hanging position.
In Slender Fortress Edit
Luigi is a hit and run boss that is in boss pack 1 and is partnered with Luigi Doll, and is a hit and run chaser. He spawns behind people with a jumpscare and the words "Mario" in distorted text. He despawns a few seconds later if not looked at. If you do look at him however, he lights the player on fire, much like Luigi Doll.
Luigi's Hanging position is a nod to a posing glitch in the original Luigi's Mansion when Luigi picks up a phone-call from Toad. Shortly after Luigi Picks up the phone, a perfectly-timed lightning strike lights up the room for a moment, where we see Luigi's shadow hovering above the ground with his head leaned awkwardly to the side, appearing that he hung himself.
