Balto is brown-grey in colour, patched with silver-white.He has brown eyes and big paws. Balto is average-built, he is not muscular nor scrawny,but he has a slightly unkempt appearance.
Balto is brave but not a very good fighter (as Steele flings him against a rock with ease) but will not hesitate to save his friends.He is also very selfless and modest, although having a fragile pride (such as snarling when Steele insults him or saying in Balto:Wolf Quest that other dogs still tease him just because he is half wolf.) Balto is also very sensitive about his half-wolf heritage in the first movie, but gradually comes to accept it.
Although Balto is modest in most movies, he is shown to be quite arrogant in Balto II - Wolf Quest, as he says "Some people still tease me just because I'm half wolf". and orders al the wolves from Nava's pack around.
- The real Balto was a purebred Siberian husky, not a wolfdog like the film character.
- People were thinking of a 4th movie for Balto, including his full-blooded wolf cousin Tecumseh. But that be came just an idea and never became a film.
