In the latest New Moon clip to hit the web, fanpires finally get a look at Jacob (Taylor Lautner) and Edward (Robert Pattinson) battling it out!

When an annoyed Edward sends him flying through the forest, Jacob transforms into a werewolf and comes charging at the vamp, leaving Bella (Kristen Stewart) stranded between the two, desperately calling for an end to the fight.

The Jacob-centric preview features new footage of Bella's best bud in werewolf form, including scenes from the wolf pack's attack on villainous vampires Victoria (Rachelle Lefevre) and Laurent (Edi Gathegi). "We only kill who we're trying to protect you from," Jacob declares.

Lautner, 17, who famously fought to reprise his role, is sure to steal fans from the Team Edward camp according to costar Jackson Rathbone, 24.

"I think people are going to be really blown away by his performance," the actor – who plays Cullen clan member Jasper Hale – told MTV. "You have these great moments that Jacob just completely is winning over Bella. And it's just beautiful to see it."

New Moon hits theaters Nov. 20.
