Phipps is a reserved and apathetic individual. Of the two Charles, Phipps is the more serious one, often responding solemnly to statements the other makes and approaching situations with a significantly calmer demeanor. While Grey tends to be inquisitive and skeptical about certain situations, Phipps, on the other hand, favors comprehensively executing the tasks dictated by Queen Victoria as instructed, without going astray or unduly interfering with matters that are not of his concern. He views seemingly odd circumstances in an objective, pragmatic light and attempts to reason with Grey; such as when Grey held doubts about Ciel and Sebastian's unbelievable speed in delivering a package, Phipps simply assumed that Ciel must have utilized his numerous connections in the underground society. In another stark contrast to Grey, Phipps isn't as inclined to fighting; on one occasion, he merely watched as Grey took on Baldroy and Mey-Rin alone, and helped Mey-Rin up after Grey knocked her down. Nevertheless, Phipps is extremely skilled and capable of moving at high speeds. He, as well, demonstrates diligence in keeping things clean and orderly; on one occasion, he'd sewn a flower onto Finnian's hat in order to patch it, something Grey deemed peculiar - Phipps merely insisted that he can do such work because he's a "top-class butler." He later made the same comment regarding his ability to play a snake-charming flute. Furthermore, Phipps has an exceptional aptitude for art, and likes to cook and paint. He also has a soft side for cute things. Before his and Grey's initial appearance, Charles Phipps was mentioned in Queen Victoria's letter to Ciel. In the said letter, Phipps made Christmas pudding with the Queen while Grey and John Brown praised it. Phipps may be based on Sir Charles Beaumont Phipps, who assisted Sir Charles Grey as a private secretary to Queen Victoria.At a fencing match, a young Phipps and Grey watched as two opponents fought each other. Phipps asked if the victorious contestant was Alexis Leon Midford's son, the one rumored to be a genius with the sword. Grey corrected him, revealing that the genius was the daughter, Elizabeth. Phipps observed her curiously while Grey scowled. Some years later, Phipps and Grey attended and graduated from Weston College.
