K-9 is a Transformer in the Beast Wars Universe. He is a member of the Maximals. His beast mode is a German Shepard Dog. K-9 is befitting of his function as a guard. His canine senses keep him aware of his surroundings at all times. His dog-like agility and strength give K-9 the edge against any intruding Predacons. If that fails, he can always try leaking lubricant on his opponents as a last-ditch effort. It might cause them to rust.
