Bran is the son of Thunderdell in Jack and the Beanstalk: The Real Story. Bran is a kind, caring and thoughtful child who frequently has a smile on his face. After the death of his father, Bran learns the importance of thinking for himself and drawing his own conclusions about what is right.
Thunderdell stated that his son had a good heart, a statement which Ondine later agreed with when he encouraged her to save Jack Robinson, realizing that she was in love with him and that he was nothing like the first Jack. He said that perhaps Ondine had just fallen in love with the 'wrong Jack' the first time.
Gallaga the goose refers to Bran as a "clumsy boy".
It is strongly implied near the end of the film that Bran will take Thunderdell's place as keeper of the goose and harp.
