Demon Timmy

Demon Timmy, also known as The Creature of The Night, is a character based off of Tantrum Timmy. He is a minor character, only appearing in a single video. There is an article here that goes into more detail about the video he stars in.

Personality
Usually, whenever Demon Timmy is seen, they are very aggressive, and appear to try attacking anyone who comes anywhere near it. He has a strange reaction to light that effectively stuns him, which is the very reason why he is rarely seen at daytime.
