First of all, the origin of Violent Bear is the toy Bearbrick's "Building Block Bear" produced by Japanese MEDICOM Company. In principle, violent bear does not refer to Bearbrick, but a blood-pink bear. The English name is gloomy, written by MoriChack, an illustrator in Osaka. As for why there is confusion about the concept of various bears in China, and even several similar bear images are collectively referred to as violent bears, it should be because these images and toys did not enter through official channels and formal agents when they first entered China, which belongs to folk circulation. So there is a risk of infringement.

The fluid violent bear is actually DIY for the violent bear. After coloring with various pigments, it is directly operated on the white violent bear and then dried.
