The New York Times bestselling Injustice team of Tom Taylor and Bruno Redondo take on Nightwing! Nightwing is back—and his drive to keep Blüdhaven safe has never been stronger! But his adoptive city has elected a new mayor with the last name Zucco. When Nightwing enlists Batgirl’s help in investigating the politician bearing the same name as the man who murdered his parents, she unearths details that will shock and fundamentally change the hero. Dick Grayson’s big heart has protected those persecuted by bullies in his youth, combated evil alongside Batman as Robin, and pledged his newly inherited wealth to enriching Blüdhaven as Nightwing. His kindness and generosity have always guided his life. But now a new villain stalks the back alleys, removing the hearts of the city’s most vulnerable. Who is this terrifying new menace named Heartless, and will he be able to resist plucking out the biggest heart in all of Blüdhaven? Collected in this Infinite Frontier Nightwing evolution are issues #78-83.
