Bold is a red fox who appears in the books and the TV series. He is the son of Fox and Vixen and was born during their first spring in White Deer Park. From a very young age Bold showed an amazing amount of courage which the other animals said he got from his father. However Bold would often have more bravery than common sense, which would get him into trouble many times throughout his life.
In the books he leaves the park because he wants to explore the outside world, but in the tv series he leaves because he needs space away from his family. He suffers many hardships in the outside world and eventually dies after returning to the park with his mate Whisper.
