Wendy's an excellent shot, based in no small part by numerous hours playing ultra-violent video games (oh, how I love my canon) and honed further by her Middle-training. The main gun-type weapon she uses is a a blaster/laser gun referred to in canon as an atomic de-moleculizer, but she's also used whatever's handy including crossbows, and a deck-mounted harpoon cannon.

She's also quite skilled with the nearest-large-blunt-object school of weaponry. Poor Noser's guitar.
