Dan Rubinstein

A background figure who quietly threads through some of Marvel's most charged Modern Age storylines, Dan Rubinstein made his first appearance in 2001's Ultimate Spider-Man #9, brought to life by the celebrated team of Brian Michael Bendis and Mark Bagley. Over a span of roughly twenty years, he turns up across a notably varied stretch of Marvel publishing — from the walls of the Ultimate Universe to the gritty, morally complex terrain of Civil War: Punisher War Journal and Civil War: War Crimes. He shares his pages with heavy hitters like Spider-Man, Peter Parker, and the Enforcers trio of Fancy Dan, Ox, and Montana, which tells you something about the kind of charged, street-level company this character keeps. With 18 catalog appearances across two decades, Dan Rubinstein is exactly the sort of supporting player that rewards the attentive reader who pays close attention to the margins of Marvel's bigger stories.
