If she ran around swinging a huge heavy bass guitar sword, that could be the hulk go smashy smash deal right? Maybe her wish would be cuz she was a teen who just wants everybody to shut up and let her play music?

for the sword and shield type, would i be allowed to have her wish be something like wanting to protect rock itself? Because people say rock is dying. Than she would have a big giant shield and an electric guitar?

Idk... These ideas i am having seem cliche, and... Whats the word... Stale?
