Jazmine is the youngest child and only daughter of Richard Becket and Dominique Lapierre-Becket. She and her brothers, Yancy and Raleigh, are raised comfortably in Anchorage, Alaska. She plays games frequently with her brothers, particularly Monkey-in-the-Middle. Richard and Dominique would take Jazmine and her brothers on trips outside of Anchorage, traveling to such places as Munich and Budapest.
Sometime after the first Kaiju Attack on August 10, 2013, Jazmine’s mother is diagnosed with cancer from habitual smoking. After her funeral, Jazmine and her brothers visit her grave. Raleigh begins whistling a song from their mother’s favorite artist, Brel, and Jazmine tells him to shut up. Shortly thereafter, Richard abandons Jazmine and her brothers, and Raleigh and Yancy forgo the rest of their education to join the Jaeger Program.
Prior to the release of Pacific Rim on DVD, Travis Beacham confirmed that Jazmine existed in his "world bible" but would not discuss any further details.
