Dollmaker

The Dollmaker (also known as Doctor Angus Bumby in the real world), is the main antagonist of Alice: Madness Returns.

Alice's Psychiatrist
Angus Bumby first acted as Alice's psychiatrist after she left Rutledge Asylum. Running an orphanage in Victorian London, Dr. Bumby appears as a stern but meaningful psychiatrist who uses hypnotism in his work to help his child patients to forget their bad memories, but Alice proves to be his most difficult patient.

Bumby Exposed
However, Dr. Bumby is revealed to be responsible for burning down Alice's house. He has actually been trying to erase Alice's memories to cover up his tracks. Bumby then planned to pimp her into prostitution as he has done so to numerous other children beforehand. As a result, Wonderland is corrupted again, now by the Infernal Train, a hellish train made out of Gothic buildings and the Ruin, oily monsters made out of doll and train parts, which are spawned from the Infernal Train.

Queen of Hearts Explains
Alice learns from the Queen of Hearts that Dr. Bumby was responsible and it is implied that he raped Alice's sister Lizzie before burning down her home, intending to kill the entire family to cover the crime.

Confronting the Dollmaker
Alice ventures into the Dollhouse where she meets Dr. Bumby's twisted other self, The Dollmaker, a giant deformed version of him with oil flowing out of his eyeholes and he has puppeteer-like hands. The Dollmaker is confronted on the Infernal Train, Alice successfully defeating him after speaking with the Mad Hatter, Caterpillar and the Queen.

Confronting Angus Bumby
In London, and parallel to the events aboard the Train, Alice corners Dr. Bumby in Moorgate Station where he is waiting for the train that will deliver his next patient, soon to be his next victim. During their discussion, Bumby speaks of his crimes with relish, but scoffs at Alice's threats of telling the truth to the authorities, as nobody will believe her due to him being a respectable citizen and her being a former lunatic. As he takes out his watch to check the time, Alice sees with rage that the key to Lizzie's room dangles from it, as that the doctor had kept it as a trophy for his crime. Now with confidence, Alice pushes a startled Dr. Bumby into the path of the oncoming train, killing him instantly. The memories that unlock short pieces of dialog relating him to Alice's past, take the shape of his spectacles.
