First you must get a record of 1000m on home run contest with gannondorf. Then complete adventure mode on very hard. Beat bowser then giga bowser. The giga bowser trophy will fall off the side of the stage as normal then you will hear master hands laugh he is holding the gannondorf trophy. The credits will go by then it will say a new challenger has come. It will be gannondorf beat him and he will turn into a trophy then the tropy will change into gannon beat gannon and yo will have him. He will be next to pichu at the bottom row.
