Elh was an unused antagonist and boss in the 2001 video game Luigi's Mansion.
When hacking into the final game's files, it reveals a pale figure with screwed (seemingly) support-beams as a body and long arms, but the design is missing a head. It had a seemingly floating animation when going forwards.
Unused animations reveal that it would be able to smash it's arms on to the ground when attacking Luigi. Other animations suggest that it would be able to summon fire and ice. Two of the animations where titled "elh_fire_b" and "elh_ice_b" which shows Elh spawning fire-like and ice-like particles, where the "b" could stand for "breath", meaning it would breath the fire and ice. The other animations where called "elh_fire_ai" and "elh_ice_a" which could either mean that it would be able to summon fire and ice another way, as the animations for the fire and ice are more clear and strengthened, or that the programmers couldn't decide which way it would be.
Either way, it suggest that Luigi would have to suck up the fire and ice and attack it using the fire and ice element on the Poltergust.
