The Beast of Apathy. A woman with a quiet and perpetually hollow personality. She has pure white hair and grey eyes, though her eyes occasionally turn black; she usually keeps them closed.

The Beast of Destruction. A man who always seeks destruction and possesses a very violent personality. He has long black hair and red eyes. He formerly represented History. He speaks in imperatives. 'Boring, I say, boring!'

The Beast of Deceit. A sly man who is actually the most short-tempered among the Beasts. He has mint and blue heterochromia and white hair. He formerly represented Knowledge. Among the Beasts, he feels the most betrayed by and loathes Silent Salt Cookie. 'You want to fight me? I don't think so~!'

The Beast of Sloth. A woman who is fanatically obsessed with the happiness of Cookies and has a calm, gentle personality. She has red eyes and pink hair. She formerly represented Happiness. Among the Beasts, she is the only one who feels betrayal instead of anger. 'Welcome to the paradise of happy sloth~'

The Beast of Silence. A very taciturn man who loathes the Beasts more than anyone, despite being one himself. He always wears a black helmet, so his face is never seen. He formerly represented Solidarity. He is the Beast Cookie who betrayed the others and chose the Cookies. Usually silent, but when angry or excited, he pours out a torrent of words laced with rage. He is the one who sealed the Beasts alongside Guest in the past. Though he doesn't say it, he feels a sense of camaraderie and trust toward Guest. 'Words are unnecessary...' . . . 'O Seal Tree! I willingly imprison my dough beneath your roots.' 'O Seal Tree, crush the fallen dough beneath your roots with the Divine Silver Fork!'
