Empty House: The Adventure at the Empty House is a Noble Phantasm of Sherlock Holmes. It allows him to disguise himself as other individuals, including Heroic Spirits. It is not a perfect imitation, since the parameters he imitates cannot exceed his own parameter values, and he cannot use the skills and Noble Phantasms associated with Heroic Spirits he imitates.
During the events of the Shinjuku Singularity, Holmes used Empty House to disguise himself as Edmond Dantès. He was recognised as a fake when he referred to himself as Edmond Dantès, instead of The Count of Monte Cristo.
