Zipstar was a cat that grew up fighting other cats and even dogs for the entertainment of humans. When her mother perished in a fight against a dog (A fight that was set up purely to kill her off), she decided to escape together with her mate and 4 kits. However, that same dog that killed her mother, had come after her and her mates. One of the kits got caught by the dog, and her mate, Blue, went in to save the kit. Blue and the kit didn't make it. In panic, Zipstar ran, but to her horror only one kit made it through the edge of the fence.
Weeks passed, and Zipstar and Grasskit found a warrior cat clan, in which she was taken in. After moons of being in there, her clan was attacked by a hostile one, and most were killed in cold blood. Running from the crime scene, filled with anger and confusion, Zipstar called upon rogues and loners to start their own clan: Battleclan. Moons passed, and Battleclan soon became a well known clan around the plains.
After a few moons, Zipstar found an abandoned kit, Squirrelkit. She raised it like her own, training it alongside Grasswhistle. Soon, she became very attached to the little kit. But peace would not stay for long...
Terror was brought down upon the clan, as the very dog that had ruined her mother's, mate's and kit's life appeared at the camp with his own newfounded pack. Zipstar, terrified of dogs, had wanted to run, but the dog already took a hold of Squirrelkit. Filled with anger from the past, Zipstar launched herself at the dog, alone. Blood was spilled, mostly her own, but the adrenaline and anger kept her fighting. A mistake from the dog caused his own downfall, as a lunge at the cat launched himself into a ravine, tumbling down the rocks and landing on a bunch of sharp dogs. Zipstar had won.
However, the wounds were too much. While this usually would not be a problem, Zipstar had never gotten her 9 lives, as Starclan had never accepted her. She died between the paws of her two children: Grasswhistle and Squirrelpaw.
