Suggested by Destroyer Sailor Jupiter is a strong Sailor Scout who doesn’t even need her elemental powers to win here. She is a solid hand to hand fighter and Goomba doesn’t really have any hands to fight back with. She would quickly outmanuever him throughout the fight and take a decisive lead in the fight. If she wanted to end this sooner she could just fire a thunder bolt as well and it would have the same effect. Sailor Jupiter wins.
