Duke Caboom is a supporting character in Disney/Pixar's Toy Story 4. He is an amiable Canadian daredevil toy with a white outfit, a horseshoe mustache, and a toy motorcycle. He suffers from low self-esteem due to believing that he let down his previous owner, unable to do the stunts that his commercial ads had promised.
Duke encounters Woody and Bo Peep when he was asked for help to rescue Forky. He gets Woody, Buzz, Bo, Giggle McDimples, Ducky and Bunny to the antique store to rescue Forky, but when they run into Gabby Gabby and The Benson, they exit the store and Duke crashes. Woody begs him and everyone to return to the store, but he and everyone leave.
After Woody gives his voice box to Gabby Gabby, Duke returns with the gang and helps Woody return to Bonnie. Woody returns to his gang but he chooses to stay with Bo instead of returning to his Bonnie. After Woody said goodbye his friends, Buzz Lightyear and Forky, Duke and everyone begin their quest in finding lost toys find homes and owners.
