Well the thing is, I don't mind him being similar to Kirby. But I wouldn't call him a clone. Besides, people mostly dislike Mallow because he isn't a really great party member to have (IF you don't know how to use him!)
Ah, pretty nice action pose. Never quite knew how or why he's able to separate his body like that (or how he didn't realize frogs couldn't do that.) I always did like the character too, he's fun and silly in his own right. And there's something about being able to control weather that earns quite a bit of respect.
By the way, I always found it weird/interesting that every character in the game has their own ''magical symbol'' when casting spells. (Peach with the heart, Mario with the spades) It was a nice little touch. ;3
