Alvarez is a detective who works in the Gotham City Police Department. Whilst dismissive of new recruit Jim Gordon in the beginning, he later became one of his most trusted allies in the fight against crime in Gotham City in the years to come.


Working for the GCPD

Alvarez was one of the many cops to leave the GCPD building when Victor Zsasz came looking for Detective James Gordon.[1] When Gordon arrested a doctor with unethical practices that Alvarez regularly used as a source, Alvarez argued with him. He later was reluctant to assist Detective Bullock with searching buildings that were used to host Richard Sionis's fights, though he decided to help as long as Bullock agreed to keep covering with his wife.[2]

Later, when Gordon found enough evidence to prove that narcotics detective Arnold Flass was responsible for the death of Leon Winkler, a witness to a public homicide that Flass was responsible for, Alvarez and Essen were the first GCPD officers to step up and support Gordon in arresting Flass, particularly when the latter started threatening the former.[3]

Alvarez later called Jim Gordon and informed him that Eduardo Flamingo killed Officer Katherine Parks while being taken to lockup.[4]

Infection and rampage

At some point during Alice Tetch virus rampage, Alvarez is infected with the Tetch virus and goes on a rampage. He guns down several officers before being stopped by Alfred Pennyworth and Lucius Fox.[5] After a cure was found for the virus, Alvarez was treated and returned to duty at the department.[6]

No Man's Land

Alvarez is one of many cops that chose to stay behind in Gotham during No Man's Land.
