I acquired this character back sometime in 2011 from I cannot even remember. But I hen started to sketch the guy up and never finished it. Was inspired recently to start redesigning this guy and giving a story to him.
(Also the headshot was heavily inspired by The Property of Hate's RGB)

Copy pasted from my idea docs on this guy
"It is known as Watcher or The Watcher. A benevolent creature that is suppose to only watch and observe... interviening could get troublesome. It doesn't speak but can use pictures on its face to communicate... normally it only has a green line that pulses like that of a heart beat. If attacked watcher will run.... but there are ways to provoke it by breaching its screen.

Watching is sort of a living prison. Behind its screen lies a terrible fearsome monster, which is why it watches... it must always asses the dangers of approaching any one or any situation. Interfering in or interviening in troublesome situations could lead to its screen being damanged. (Watchers antlers are not real... they are an asthetic that pleases Watcher and can be reformed if damaged. they have the possibility to go transparent or start to fall apart or disappear if Watcher himself if severaly damaged)
if only slightly damaged then Watcher will sit still in a single location, its screen displaying a 'please stand by' or 'do not disturb' sign.
if moderatly damaged then Watchers screen will display nothing but static or maybe even color bars... showing that it doesn't even had the strenght to put up a proper image.
Sevearly damanged Watchers screen will go completely black and its body fully limp. Having to put every bit of remaining power/energy into keeping in the monster contained and repairing the damaged.

If severaly damaged there is a chance the monster will be able to 'leak' out. If that happens it can then posses and control Watcher, its screen showing lots of frightening images like that of a large eye, many small eyes or nashing teeth. The design of which can vary and fluctuate second to second. The screen and wound will also leak black slime, blood and puss as the monster attempts to push its mass and vile existance into the real world.
-only two outcomes can come from this... either watcher regains control of its body and seals away the monster again or the monster remains in control until it breaks free.
-Watcher would most likely die if the monster were to escape.
-there are ways to help Watcher regain control by temperarily subduing the demons power."
