I got a idea from One Piece Movie 10 - Strong World, after I saw Strawhat Pirates fight Shiki outside the village and take Nami with him, I shall added a battle between Mario and Asylus in Tatanga story arc.
In the end of the battle, Mario lost and Asylus destroy the Star Radar.
Super Mario Bros GT The Grand Adventure aka SMBGT-TGA and Asylus (c) Yours Truly aka ~xXKaijuKing91Xx Mario; Super Mario Bros Series (c) Nintendo
This time I put Celine, Maple, Knuckle Joe, Kenny Shy Guy, King Lakitu, Kamek and Kammy.
