Sui the Gray is a fan-made antagonist in Abandoned: Discovery Island.
STG was a special revision of a Suicide Mouse suit, but was deemed as defective for his disturbing appearance. He was later replaced with Mickey the Monochrome. STG is the "second-hand-man" of PN Mickey the Defective Performer, and acts of a henchmen of sorts.
STG is a dusted, abandoned mouse suit, with a large red top-hat, grey cheeks, red bow-tie, red buttons, and red shoes. He also has two gold stars on his gloves.
STG starts in the Storage Room, where he's seen hanging on a hook. At 2AM, he moves to the Meat Freezer, where he is seen, laying in a slumped position on the floor. He then moves to the Lounge, where he is seen in the corner, standing there.
He will finally move into the Office, where he is seen standing far away from the desk. The player must turn off the power to get rid of him.
- "Why did they replace me?"
- "Why must you exist?"
- STG has a grudge against Mickey the Monochrome for replacing him.
- He suffers from hallucinations, and thinks Jake is MTM, prompting him to attack Jake.
