Fan Art for a free indie horror game. The game has the same title.
Spoilers:
The "uncle" is not, in fact, anyone's uncle. He is a being who preys on lonely children by offering them everything they could want (in terms of video games) in exchange for feeding the uncle. The uncle keeps his part of the deal, and he creates and maintains an artificial world for the child while giving them the best consoles, the newest games, all the secrets, things no child could otherwise have access to.
The game is text and audio based, and so there's no real official version of the uncle. Based on context clues, the uncle is a tall, dark figure. The story takes place in the N64 era, so I decided to give him a pixel-y, polygonal look. The uncle appears to feed when he's weak and hungry, and his reality-bending powers are weakened, so I gave him a glitchy look.
