A DVD titled The Ultimate Battle was included with the Classics Optimus Prime / Megatron two-pack. The domestic version includes a gallery that features the Classics line and a special episode of various clips from the Armada, Energon and Cybertron series. The international version drops the gallery of the Classics line in favor of multiple languages for the episode.
The episode features a voiceover of Optimus Prime (voice of Gary Chalk) explaining the basics of the Transformers Unicron Trilogy universe. The differing appearance of any recurring character between Energon and Cybertron is explained as being an upgraded or rebuilt/rescanned body. Many of the big names make their appearance in this episode, even Supreme Starscream and Cybertron Primus, but Unicron himself is strangely absent throughout the whole feature.
