Description
Stacey Pilgrim, Scott Pilgrim's younger sister born in Canada in December 1984, is 19 during the series' main events and turns 20 by the sixth volume. She works as a Second Cup cashier alongside Julie Powers. Despite being four years Scott's junior, she frequently exhibits greater maturity and responsibility, sometimes calling him her "little brother." Her personality features freely offered blunt commentary on Scott's romantic life and choices, coupled with a strong propensity for gossip—often fueled by text updates from Scott's roommate, Wallace Wells.

She maintains a complex bond with Scott, fluctuating between criticism and authentic care. She actively participates in his conflicts, aiding against Matthew Patel at Club Rockit and later attending his final battle against Gideon Graves at the Chaos Theatre. During that battle, she attempts intervention and contacts their mother. After Gideon's defeat, she directly challenges Ramona Flowers about her pre-battle absence. Her care manifests as tough love, pushing Scott toward responsibility while providing emotional support during his lows, like Ramona's temporary departure.

Her social circle includes friendship with Ramona, involving mall shopping trips, and with Wallace—though she voices frustration when he repeatedly "steals" her boyfriends, like Jimmy during a concert. She dislikes cats, finding their movement unnatural. Her hobbies include eating wasabi with sushi and wearing graphic T-shirts featuring motifs such as the Super Mario star or Superman logo.

In *Scott Pilgrim Takes Off*, Stacey initially believes Scott died after witnessing Matthew Patel seemingly defeat him at Club Rockit, leading her to attend his funeral. Still employed at Second Cup, she reprimands Julie for swearing at customers and later gossips about Julie and Gideon's relationship. After learning Scott is alive, she is briefly interviewed by a documentary crew. She attends the opening of "Scott Pilgrim's Precious Little Musical" and cheers at its conclusion. The epilogue shows her continuing at Second Cup, now alongside Lucas Lee, while gossiping on the phone about Lee's physique and the resulting good tips.

Supplemental reports from an alternate continuity classify her as a "Class 4 Psionic" metahuman. Her abilities—telepathy, telekinesis, telesthesia (limited remote viewing), and telegnosis (enhanced sensory perception)—manifested after a childhood garage fire caused by Scott, where she inhaled smoke. She possesses genius intellect, fluency in numerous languages, mastery of hacking, martial arts, and occultism. Key weaknesses include overwhelming curiosity bordering on nosiness and her tumultuous sibling dynamic with Scott.
