Margo, a female Imroosian, served as part of Dryden Vos's concierge team on the First Light. This took place around 10 BBY, during the yacht's mission to retrieve stolen coaxium from Tobias Beckett and his crew.
Aboard the First Light, Margo's duties included managing all guest amenities. She greeted Beckett, Han Solo, and Chewbacca upon their arrival. Inquiring about their purpose, she was informed by Beckett that Dryden Vos was expecting him for a scheduled meeting. After Dryden Vos dealt with the Regional Governor, who was subsequently killed by the crime lord's kyuzo petars, Margo suspected Kara Safwan, a party guest, of being a spy and blocked her from getting closer to Dryden Vos.
Margo's attire aboard the First Light consisted of a black shimmersilk gown and an Ottegan charbake smelt necklace. Her physical characteristics included brown eyes and chalky skin. Despite her homeworld, Imroosia, being a volcanic planet, Margo disliked the searing heat and preferred the cool atmosphere inside the First Light.
Charlotte Louise played Margo in Solo: A Star Wars Story, a Star Wars Anthology film released in 2018. Her design was based on reused concept art initially intended for Qi'ra, when she was to be an alien. Louise was cast in the role after the 2017 release of Star Wars: Episode VIII The Last Jedi, a sequel trilogy film. Despite initial reservations about the plaster costume, she found it easy to adapt to the role and enjoyed collaborating with the CFX team during the film's production.
