Terrorglass is a fan made antagonist on Abandoned: Discovery Island.
He is one of Father's men and was designed by him from Hourglass by duplicating him and use some type of chemical to mutate the duplicate into a monster known as "Terrorglass"
He appears to resemble Hourglass except he only has a large mouth with spiky teeth as a face, and his hands are slightly bigger with sharp claws and his arms have retractable blades. His skin color appears to be dark green and his body is sinister looking. And he as the ability to climb on walls, ceilings, and can spit acid.
Terrorglass starts at night 2 in the Storage Room. Unlike the other enemies, he can sometimes be seen climbing on the ceiling. In some cameras, it blocks the view. If Terrorglass looks at you in one of the cameras, you must go to another camera or he will use his blade to destroy that camera, it can be repaired by a help from God. When in the office, the player must hide or he will kill them. He can also spit acid on you, which can kill you overtime if you stayed in effect too much. Use God's assistance to heal you.
Terrorglass starts at the Storage Room, then heads to Staff Area, Meat Freezer, Lounge, and the office.
Terrorglass is the first enemy you encounter that works with Father.
Terrorglass can twist his head like Hourglass.
