Four is the host of Battle for BFDI, the fourth season of the animated object show Battle for Dream Island, which is published on YouTube by the creators jacknjellify. As the show's energetic and sometimes unpredictable host, Four became a fan favorite, and short clips of his voice spread through fan edits, memes and reaction videos on YouTube and TikTok. Because Battle for Dream Island has a long-running, highly active fan community, even a brief Four sound remains instantly recognisable and useful for signalling a BFB moment.
