Suggested by Sonic Tiki may not be quite as well known as some of the heavy hitters like Marth and Lucina, but she can certainly fight quite well. Her attacks deal a lot of damage and she attacks with great speed as well. Bowser won’t be able to keep up with her and while his defense is pretty good, he’ll still end up taking a considerable amount of damage from her attacks. He won’t be able to land any good counter attacks so the damage will continue to build up more and more until his defeat is certain. Tiki (Fire Emblem) wins.
