Bowser complete!

Good weapons for Bowser would be Dual Wield Claws and his armor can be called a Spike Shell and can replace the Snow Muffler and be all of his base defense. Good equippable relics can be the Genji Glove to enable dual wield. Bowser could also use the Flail or Morning Star as well. As far as Magic, he should be only able to use Black Magic. If he's attacking on his own when his turn comes up like Umaro that's a different story. The Blizzard Orb and it's effects can be changed to a fire move.
