Rottweiler

He's a monstrous dog who is unstoppable when locked on a target from the 2004 film Rottweiler.

He was first an ordinary security pet owned by a rich man. The man owned a a labour camp where he puts useless and poor men who cannot pay their debts in it. During a daring prison escape by a man named Dante and his girlfriend, the Rottweiler was beaten up while trying to protect his master.

Because of its injury the rich man payed scientists to turn it into a cyborg. But after the operation the dog transformed from a loving pet into a killing machine. Seeing the new attributes of the dog, the rich man puts him in security in his prison to prevent more prison breaks. The rottweiler met a new caretaker whom he felt closed to.

While on the search for the escaped Dante, the rottweiler proved his monstrosity by killing and hunting those who escaped earlier. When they already captured Dante, he again tried to escape by reaching for the security's shotgun. He managed to reach it and shot the rottweiler and the guard. Sensing the danger is over Dante tries to find his girlfriend. The rottweiler suddenly wokes up and sees his caretaker brutally shot. It then swore revenge on Dante and tries to track him down.

The rottweiler shows extreme levels of intelligince by throwing Dante's gun into the river and avoiding firepower from guns. His cyborg quantities gives him invulnerability to pistol shots andand other arilleries.

Even as a cyborg the rottweiler shows cannibalistic attributes shown when he devoured both humans and his fellow guard dogs. The rottweiler hunts Dante down all for his deceased friend, a thing still shown in modern dogs. Burned and bruised during his hunt for Dante, they finally faced each other in the burning prison camp after Dante discovers that the rottweiler killed his girlfriend, both of them died for vengeance of their loved ones.
