Stone (StoneBreaker)

StoneBreaker is a black wolf with yellow eyes, the wolf that introduces Storm to the Diamond Wolves

SPOILERS BELOW

In the first story, Stone meets Storm, and takes him to the leader of the Diamond Wolves. He fights Storm for Storm to join, and loses.

In the second story, Stone scolds Storm at being carefree and is glad that Storm would be getting his Agent soon enough. Storm protests and runs off, where he growls that it wasn't for Storm to decide.

In the third story, a black-and-brown wolf named SwiftWind races to MoonHowl, yelling that there's been a murder. Stone is sent with Storm and SwiftWind to investigate, and they return with no luck. Stone questions SwiftWind about his deceased sister. In the end, the audience finds out that Stone is the murderer.

In the fourth story, Stone tries to get Storm to join him, but Storm fights back and races back to the Diamond Wolves. He's too late because Stone has killed MoonHowl, and has the Diamond Wolves under his control with the Acceptance Howl, telling them that he'd protect them from the "unknown murderer." In the very end when Snow asks him what they would do next, he says, "We wait for them to come to us."

In the fifth story, when Storm and Frost attack, Stone howls and the magic of the Acceptance Howl forces the Diamond Wolves against Storm and Frost, causing them to run away.

In the sixth story, Stone kills all of the traitors that helped Storm and Frost, and SwiftWind acts very weak as it's his turn to get killed so that he can escape back to Storm. SwiftWind is sent back that night, covered in ashes, but Stone still knows who he is and claims that he'll kill SwiftWind and Snow will get Storm and Frost at the same time. Frost later sees something in the water, and they realize it's SwiftWind, dead and still bleeding.

In the seventh story, Stone is telling the Diamond Wolves that they must take the attack to Storm and Frost when it begins to rain and Storm pretends to be Stone. Stone doesn't fall for the trick and the disguise is off Storm, so he declares that he could never be Stone because Stone is pure evil. Stone then says that the next time, he should have a better plan, but that there'd be no next time. Frost comes up behind Stone and kills him, saying, "You're right about one thing. There won't be a next time!"
