Boris Goosinov (called Uncle Boris by Muk, Luk and sometimes Balto) is a Russian snow goose who raised
Balto from a pup. He is the tritagonist of the first film and a supporting character in the sequels. He speaks with a heavy Russian accent (but in the closed captions for Balto II: Wolf Quest, it says that Boris has a Yiddish accent). He is voiced by the late Bob Hoskins in the first film, and Charles Fleischer in the direct-to-video sequels (both voice actors starred together in Disney's and Touchstone's film Who Framed Roger Rabbit as Eddie Valiant and the voice of Roger Rabbit respectively). In the 1st film, Boris mentions his last name is "Goosinov".
