Reception.
In the August–September 1986 edition of "Adventurer" (Issue #3), the reviewer thought the first edition of this supplement was "a reference work of great value to anybody wishing to play the part of Batman, or interested in his friends and foes." The reviewer concluded, "this is an excellent piece of research, well supported with illustrations and plenty of detail." 
In the January 1990 edition of "Games International" (Issue 12), Mike Jarvis reviewed the second edition, and found the mixture of upper and lower case letters in section titles to be "messy". Although he enjoyed reading the descriptions of famous Batman foes — "a delight to read" — what drew his interest was the essays about Batman. Although he thought the included scenario was "nothing spectacular, it should prove entertaining enough." He concluded by giving this supplement an above-average rating of 4 out of 5, saying, "This is a high quality product [...] If all the supplements for the new edition of "DC Heroes" reach this standard then the future of superhero gaming looks rosy indeed." 
In the January 1991 edition of "Dragon" (Issue #165), Allen Varney was impressed with the second edition of the book, calling it a "polished update of one of the original edition's best supplements." Varney called the included adventure "snappy... But too bad the ending falls a bit flat." Although Varney did not like the book's graphic design, saying "all the titles look like ransom notes!", he concluded that the book's contents were impressive and complete.
