Hexafusion, often referred to as Triple Fusion, is a structured chart format that originated in digital art communities like DeviantArt and 4chan. The diagram illustrates three primary subjects—often characters from different franchises—merging in pairs, which then all culminate into a single 'Triple Fusion' in the center of the hexagon. While initially used for serious character design exercises, the internet adopted it as a meme format to showcase humorous or logical combinations of food, brands, or personality traits. It is the gold standard for representing how multiple distinct elements can blend together to create a complex, unified result.
