Tom is a young, mischevious, adventurous boy. He has an active imagination, and gets into trouble a lot. He is a born leader, and very headstrong. Throughout the book he goes through many adventures that change him. One thing that is evident when comparing Tom to Huckleberry is that Tom is very naive about people and the real world, whereas Huck has had enough of a rough life to understand that things aren't as Tom perceives them.
