The outcome of this match depends largely on whether Edgar has his tools and whether Shadow has Interceptor. If Edgar has his tools and Shadow does not have Interceptor, then Edgar could easily win. If Shadow has Interceptor, he will probably win, although Edgar might get lucky with a one-hit kill from Chainsaw (though Interceptor could respond by killing him which could leave Gogo the victor). If neither Edgar has his tools nor Shadow has interceptor, then Gogo might win.

Too many variables here to call it, really.
