Wingnut tipSent in by WingnutWith Wingnut their is a way to totally destroy your opponent no matter how much energy he or she has. When your super meter is filled up, try to position yourself directly above your opponent. When you are above him or her execute your super attack by pushing both your hard kick and punch buttons. If done correctly, all of wingnuts wing blasts should hit your opponent taking away their entire life meter.
