DANI SHPAK was initially recuirted as a member of the GHOST SMASHERS by RON ALEXANDER because he figured her local noteriety as nationally ranked archer (despite never making the Olympics due to personality conflicts) might help him secure funding for his operations. He was not wrong.
Dani took to the work because of her difficulty... she likes shooting at moving targets, and ghosts are the most difficult target she's ever found.
Like Ron, Dani is a bit of a narcissit and enjoys the fame of Ghostbusting. Despite her proficient aim, Dani publicly touts herself as a team researcher to stand out from her CHICAGO GHOSTBUSTERS colleagues. (She actually only has one book on the supernatural, which she picked up on clearance at a mainstream book store.)
