Ben 10 vs. the Negative 10, War of the Worlds, Vengance of Vilgax, The Final Battle, Absolute Power, The Ultimate Enemy, The More Things Change, Of Predators and Prey & Showdown were not relased toghether, so The Frogs of War shouldn't be relased toghether. We only use them without Part 1 and Part 2 when we are talking about the 2 episodes generally, or when we are talking about something that happened in both of the 2 episodes.
