Bigwig is the deuteragonist of the Watership Down franchise, based on the book by Richard Adams. He was voiced by Michael Graham Cox in the 1978 film adaptation.
Book and Movie
In the film version, Bigwig is depicted, as most of the characters, in a fairly realistic manner. His distinctive tuft of fur is darker than his body. He is one of the larger, stockier rabbits and often has claws.
In the TV series, Bigwig is a large grey hare-lionhead rabbit mix. He at first questions Hazel's authority but later on admits that Hazel was the one who had brought them to the down making him the leader. Unlike in the novel, Bigwig is considered Hazel's right-hand rabbit, military adviser, and Captain of the Owsla.
He is much more of a bully in the TV series than in the novel and film, but also more caring especially when Pipkin becomes frightened after a weasel nearly kills him. His strength also makes him a great swimmer. Also, he is a strict follower of the Owsla Code of Honor, which dictates that when an Owsla member is defeated, he must accept that defeat whether it was fair or not.
In Episode 10 of season 3, Bigwig falls for a doe named Spartina, but little does he know that she is a spy for Woundwort and when the secret is revealed by Silverweed, Bigwig is angry and even after Silverweed showed him her heart, he still distrusts her, at one point telling Hazel that he follows his heart with Spartina, and she was a spy. However, when Spartina goes back to Darkhaven, he asks if she will come back to him, which she says she will, and it is assumed that Bigwig and Spartina settle down together.
Bigwig appears in the 2018 miniseries where he becomes the mate of Strawberry (who is portrayed as female) and has children with her.
Bigwig is a very serious, hardworking, rebellious, cold and ill-tempered rabbit yet deep down he has a good heart. He fought bravely against General Woundwort to protect his warren. He is loyal towards the rabbits of Sandleford Warren.
In the miniseries, he is portrayed as challenging towards Hazel but he later learns to respect him more. Unlike the previous adaptations, Bigwig is portrayed as more short-tempered and threatening. In this adaptation, he has less of a soft side than in the book.
