Suggested by Sonic Rosalina is a pretty skilled Mario fighter. To be more precise, her cosmic abilities are quite vast, but she doesn’t typically use them for combat. Rosalina’s barrier may protect her from some of Pichu’s attacks, but it won’t ultimately last. Once Pichu breaks through Rosalina doesn’t have enough speed to keep up. Ultimately it will be all that she can do to extend the match. Pichu wins.
