Lisa was a member of MI6, where she helped the Agents of A.C.E by assigning Kieron Hawk with the task of fighting aquatic inter-dimensional invaders. She provided Kieron with a new and upgraded suit and later the rest of the Agents. 
Upon the retirement of Kieron Hawk as leader, Richmond Clay was appointed the head of the Agents of A.C.E. Upon Kieron’s recommendation, Richmond approached  Lisa and asked her if she would become the new Agent Blue. She accepted, and the pair bonded as Richmond was trying to re-organise the Agents. She was instrumental in recruiting and expanding the roles of squadrons. After everything was fully re-established, she lead the scientific division. 
Lisa was instrumental in taking down the tripeds used by The Darkening Mind in its occupation of New Chinatown. She also helped out in fighting the evil and powerful Mob Dogs, which lead to her killing of Sweety, making her a target of Hun. After they were defeated, she assisted in taking down the League of Former Adversaries, where she was targeted by Hun also. 
After Gentleman Beast and his League was defeated, Lisa fought the Murder of Crows in an attempt to stop the, from reviving the Chairman of the Third Concord. However, despite her efforts, she was killed during these times, as she was guarding the last of the artefacts needed.
