Dr. Jeremiah Arkham

Dr. Jeremiah Arkham is the superintendent of Arkham Asylum, Gotham City's infamous institution for the criminally insane. A descendant of the asylum's founder, he walks a psychological razor's edge between healer and patient, making him one of Batman's most unsettling allies.

Few figures in Gotham's shadowy ecosystem are as fascinatingly unsettling as Dr. Jeremiah Arkham, who stepped onto the Modern Age stage in Tony Salvador Daniel's Detective Comics #1 in 2011. A DC creation rooted in the darkest corners of Gotham's mythology, he moves through the pages of Detective Comics in the company of none other than Batman, Bruce Wayne, and even Superman himself — rarefied air for any character. With only a handful of catalog appearances, he's a collector's hidden gem: a figure whose limited page count makes each issue feel all the more significant.
