Four is the host of Battle for BFB and a major character in The Power of Two, part of the Battle for Dream Island animated web series created by Jacknjellify. Known for his screechy voice, reality warping powers and unpredictable mood, Four became a favourite for reaction clips shared by fans. This high-five line spread through fan edits and soundboards because it isolates his surprised delivery in a short, reusable moment that works even without the original scene context.
