Answer and Explanation:
The characters trying to change Huck are the widow Douglas and Mrs. Watson. They feel that Huck is rude, uncivilized and behaves like a savage and not like a white southern kid should act. They feel responsible for "fixing" him and preventing him from becoming an unworthy adult and outside the social standards desired by southern society.
Widow Douglas doesn't change all of Huck's clothes, forces him to church and school, and wants him to stop unbecoming childlike habits like smoking. She wants him to become a Christian gentleman. Mrs. Watson, on the other hand, doesn't like him to be illiterate and rude. She tries to teach him to read and wants him to adopt Christian behavior.
It should be noted that Huck is the main character of "The Adventures of Huckleberry Finn," a book that tells the story of Huck, an adventurous boy, who escapes from an inhospitable environment and lives many adventures, discovering new concepts, breaking prejudices and making friendships.
