Jackie Chang

Jenny Everywhere quipped that she was “going Jackie Chang on” a group of Dwarves whom she was beating up bare-handed in retaliation for their leader trying to lash her with a whip and for them trying to take her to the Sorcerous. (COMIC: Beauty as a Beast)

Behind the scenes

This appears to be an allusion to the real-world action star Jackie Chan. It is unclear if the wrong last name used in Beauty as a Beast is a mere typo or an intentional, subtle gag, suggesting that Jenny is referencing a parallel universe version of Jackie than the one readers might be familiar with, who would have a subtly different name.
