Shortly after, a new Doctor Alchemy appears and is revealed to be his astral twin "Alvin" Desmond with whom he shares a psychic link. It was later revealed that Alvin was a construct of the Stone created by Albert's criminal personality. When Albert confronts and defeats "Alvin", he resumes the Doctor Alchemy role.[2] While incarcerated, both of his costumed identities were used by others: Curtis Engstrom using the Philosopher's Stone as the Alchemist and Alexander Petrov using the Mister Element identity.[1]:92
