History
The youngest of the legendary Roseheart family of athletes, Loucinde "Lou" Roseheart was born to Barnabas and Handlebar Roseheart in 1882 before stealing a temporal rift as a child and landing in the modern day Firehouse.
After a brief stint where she followed in her parents' footsteps as a pro wrestling tag team (alongside her partner, her own corporeal shadow), she joined the Chicago Firefighters when she leapt from the stands onto the field to catch a fly ball. Roseheart stated in her post-game interview that she was asked by a “freaky disembodied voice” (later identified as Mx. Chicago) whether she wished to join the team. She “accepted, duh,” after which then-coach Henshley Fingerlicks took the opportunity to sign her to the team in order to count the play as an out for the Firefighters. She has been stealing hearts ever since, both figuratively and literally, from Paulina Meat Market on Lincoln Avenue.
She carved her own bat from a mockernut hickory tree that fell in her backyard during The Great Storm. In the off-season she bakes bread and tends to her vegetable garden in Lincoln Square.
Like all of us, she is from Chicago. Her jersey number is 630.
