This American spy thriller series premiered on August 13, 2025, exclusively on Prime Video. Inspired by the Boom! Studio graphic novel series by Arash Amel and Marguerite Bennett, the show is created by Steph Cha and Ken Woodruff.

Here’s a complete breakdown of the characters of Butterfly

Daniel Dae Kim as David Jung: Believed to be killed in an operation nine years before, he is now back to confront his daughter. An ex-intelligence officer, he will be seen in the series as a protective father hiding from enemies and hopping from city to city in South Korea.

Reina Hardesty as Rebecca: David’s daughter, Rebecca, a skilled assassin, is assigned to kill David Jung, only to later discover he is her father, whom she believed had abandoned her nine years ago. In What’s Inside fame, Rebecca is also seen in shows like I Am Whole, What Comes Around, The Honour List, Oh Sorry, and The Flash. 

Piper Perabo as Juno: Former partner of David and a boss to his daughter Rebecca, Juno is a merciless CEO of Caddis (a private spy company).
