Kodi

Kodi, short for Kodiak (voiced by Sean Astin) is the son of Balto and Jenna, and brother of Aleu, and 4 others. He helped pulled the mail from White Mountain to Nome. But one day, a Bush Plane pilot named Duke came to Nome. Kodi and the other dogs feared they might lose their jobs. A race was settled between the plane and the sled dogs to see who's faster. Balto lead the team. In the middle of a snow storm, Duke's plane crashed. They won the race, but Duke was nowhere to be seen, which made Balto worried. Balto wanted Kodi and the others to help, put they refused. After a talking with Jenna and his team, Kodi and the others manage to help Balto and Duke just before they fell off a cliff.
