Tusk was the son of Mother Malkin and the Fiend. He was an abhuman.

After Mother Malkin's temporary death, Tom Ward throwing her into running water, Bony Lizzie and Tusk, came charging after him. Tom got to John Gregory's house though, but a few days later, Alice Deane tricked him and so, Tusk and Lizzie captured him. Lizzie commanded Tusk to take Tom to where Billy Bradley was buried and put him in a pit and when they had left, the ghost of Billy, told him that he was hallucinating. Alice returned and helped Tom out of the pit, to which Lizzie and Tusk were angry and charged at them. John Gregory arrived though and killed Tusk with his staff. He was later buried in the pit he and Bony Lizzie had planned to bury Tom in.
