Warning : this section contains some spoilers.

A Balto film wouldn't be one without Balto...But, contrary to Wolf Quest, Balto's back to the main role, and even has the most screen time. And this time, he's even the most well known dog in Nome, and considered as a hero! - even if he doesn't seem to consider that way and still sometimes doubts about himself. He's having dreams again, but no nightmares this time : he's just curious about that new plane in town...

Even if we don't see him so much in the film, Kodi's still an important part of the scenario; he's Balto & Jenna's son, from the same litter seen in Wolf Quest. He likes his parents, as well as his new job : sled-mail dog in Nome. He's proud of his father and wish that one day, he could have an important part as a lead dog in a pack.

Stella is a tourist who's decided to make a break in Nome; she encounters Boris, and immediately starts to seduce him; however, he seems to have a problem that prevents him from answering to her calls...Boris & Stella are obviously mainly for the comical side of the film (well, at least in the first half...)

Duke is the pilot of the plane; he has recently come to Nome, and think of a way for his plane to make things easier in Nome. But not everyone will like this idea...
