Maybe his dash A could be the Head Bash attack from Wario Land 4? And maybe his Neutral B could be squeeze a garlic and a green smoke come out, or eating a garlic and breaths a green breath?

Love what you did with Wario so far. But can you help me with something? When i change characters, like the Wario of yours, most of the sound effects dissapears. His voice, Wario Waft sound and so on. Do you know how to fix that?
