Blue, a Devaronian of the female persuasion, spearheaded a rebel team operating within the Five Points system. During the time of the Imperial Era, Jyn Erso found herself coerced by Imperial Admiral Bethava Rocwyn to become an informant, tasked with infiltrating and observing Blue's organization.
Accompanied by Jyn, Blue's group transported provisions to the system's planet known as Watassay. Upon their arrival, they were apprehended and taken into custody by Admiral Rocwyn. The Admiral declared that Blue would face execution for the crime of treason.
As a leader, Blue was committed and displayed a fierce intensity that, in Jyn's estimation, bore resemblance to that of Partisan leader Saw Gerrera. Despite differing opinions on her Rebel objectives, Jyn regarded her as a person of good character.
