In this article you will learn exactly how to unlock all characters in Mario Kart Wii. The Mario Kart Wii characters are arranged in three levels: light, medium and heavy. The level of the character determines what kind of car or motorcycle you can use. The characters differ in several ways. For example, Baby Mario has a weight advantage and can control his vehicle better than, say, Toad. The differences between the characters are very small and should therefore have little influence on your choice. You can find out who is your favorite by trying out all the characters.
