Stardust

Stardust is a bear that appeared in Naughty Bear. He is not a boss bear in the original game, but when the three DLC came out, he is the boss bear of the episode, along with the Vampiricorn. He takes the biggest risk of the entire game as he summoned the Vampire Bears and unleashed them on the island simply so they would kill Naughty Bear.

Personality
Stardust does not appear to be very smart as shwon in Episode 10. He summons Vampires on the island so they would suck Naughty Bear's fluff, not seeming to know that the Vampires would then kill the other bears after finishing Naughty. Summoning them was the biggest risk taken in the game, even moreso than all the other bears in the game as Stardust endangered the entire island to kill one bear.
