In early 2018, Pichon assisted Rainbow's new CBRN Threat Unit with a situation concerning a mysterious mist on the shores of Sussex. She assisted in the improvement of the team's equipment and was noted to have helped Elena "Mira" Álvarez in the development of Morowa "Clash" Evans' CCE Shield in 2017.
While not deployed on missions, Pichon proved invaluable for Rainbow's R&D Department. In 2016, Pichon met Taina "Caveira" Pereira and had some kind of relationship with her, but to what extent remains currently unknown. Later that year, Pichon's unique combination of talents made her well-suited to join Rainbow. Tragedy ensued, and the decisions Flament made for safety reasons put him at odds with Pichon and Gustave "Doc" Kateb, who blamed him for the death of several medical personnel on-site including Kateb's colleague. In 2015, Pichon was led by Olivier "Lion" Flament on a mission to Nigeria to assist medical personnel fighting the Ebola epidemic. While there is much praise for her technological achievements, Pichon's tactical prowess and ability to problem solve quickly and efficiently make her a crucial operational asset. From the start, Pichon's focus has been on adaptable technology that aids soldiers in the field. Her superiors quickly encouraged Pichon to study engineering while continuing her career in the military with the GIGN. Almost immediately her talent was recognized, particularly in robotics. Early participation in sponsored computer programming competitions led to her joining the army cadets at sixteen. Pichon grew up in a family of academics in the historic city of Nancy, France, where the children were encouraged to excel in Math, Science, and Technology.
