Four

Appearance Four, as his name suggests, appears to be a blue Arabic numeral four (4), whose design is based on the version of "4" with an open top, most likely taken from the original Minesweeper. He is drawn simplistically and have limbs that are lighter colored. Like every algebralien, Four has four fingers.In "The Great Goikian Bake-Off," Four reverts to his chaotic behavior, likely due to lingering anger at the old contestants or his commitment to guarding the hotel's food. Additionally, in the stinger for "The Seven Wonders of Goiky," Four punishes Roboty for escaping the EXIT, showcasing his aggressive and controlling nature towards those who defy his rules. His rage intensifies when Clock, his "friend," is trapped in the elimination space by Two in "Oneirophobe's Nightmare" prompting a destructive rampage alongside X. However, in "Out Of The Blue," Four's demeanor shifts slightly. While he still tries to prevent the EXITors from escaping, he becomes somewhat more amiable when they assist in the hotel's kitchen, suggesting a possible softening in his approach, at least when it involves cooperation and help. When Four takes over Two’s role as a host during their depression in "The Power of Four," he starts to show more of his old personality from early BFB—though less bizarre than before. Even with the changes seen by "Chapter Complete," Four still has no problem harming or even killing contestants without remorse, especially when they break the rules. This includes splitting Pillow in half with his tongue after she ate one of the cakes. One of the clearest examples of his cruelty shows when he smiles maniacally after zapping Yellow Face into ashes. The grin, along with Yellow Face’s ashes on him, makes it clear how dangerous and downright frightening he can be.
