I was reading the Grand Tour series by DrunkenGrognard in which Ranma gets jealous of others flying and he cant so he invents his own form, which reminded me of another fic Multiplicity by mikebreslau where Ranma goes on a training trip and figures out all his rival moves and creates a method of destroying and creating matter and then multiple bodies he can control.
Anyway im looking for more fics where Ranma gets inspired and creates his own special moves. It always bugs me that Genma is usually depicted as stupid and greedy and yet had created his own overpowered forbidden moves while Ranma mostly just copies or is taught moves and his only creativity is modifying them to work in different ways. I might also include using manga and such as inspiration in which he manages to create the moves he's seen such as in the Black Paw.
