The Grizzly Bear

The Grizzly Bear is a minor villain in Balto and it's 2002 sequel.

Balto
During the wolf-dog's journey to find the missing team, a huge, vicious black grizzly bear appears to be stalking the group consisting of Balto, Boris and Muk & Luk for several moments before Balto finally has caught the scent of the danger.

A fierce confrontation erupts between the crazed giant and Balto. Although smaller and more agile, the wolf-dog finds himself unable to match the bear in combat and is trapped and nearly crushed beneath the bear's huge paw.

Has it not been for the swift arrival of Jenna, Balto may have easily been killed. In the fight the giant bear nearly stomps on the trapped baby polar bears and Boris trapped under a tree as the bear stomps his foot towards them. Still relentless, the grizzly bear injures Jenna and manages to engage Balto once more.

Having learned a strategy, Balto lures the grizzly bear onto the frozen ice; managing to dispose of the giant in the icy depths of the lake at nearly the cost of his own life.

Balto II: Wolf Quest
The Grizzly Bear 2 When Aleu leaves the crystal cave and sees day light, a huge and furious brown Grizzly Bear attempts to kill Aleu. Balto arrives, distracts the grizzly bear, saves Aleu, and as they both escape, the grizzly bear disappears.

Trivia

 * In the covers portrays the Bear to have brown fur while in the movie it's black

 * He is the only character that dies in the movie.
 * The Bear was a spirit in the sequel.
 * Oddly, Frank Welker helped with the bear (Balto) and he isn't credited on the end credits.
