Three TV movies complied from Kidou Senshi Gundam SEED series. 1. The Empty Battlefield (Kokuu no Senjou) 2. The Far-Away Dawn (Harukanaru Akatsuki) 3. The Rumbling Sky (Meidou no Sora) Much like the Kidou Senshi Gundam theatrical movies, the Gundam Seed: Special Edition movies are intended to be an override of the story from the TV series. These episodes are in fact a complete recap of all 50 episodes of the TV series and were first shown on television in Japan. The special edition episodes feature some new scenes and tweaks to previously animated scenes. The first special, The Empty Battlefield, which compiled episodes 1–21 of the series, was aired in two parts on Japanese TV in March 2004, followed by the next special, The Far-Away Dawn, which was episodes 22–40, in July 2004. The final special, The Rumbling Sky, which was episodes 41–50. While the story is overall unchanged, there are a few minor changes. In addition, several scenes are re-animated and re-dubbed.

Zenigata arrives at the birthday party of an important politician to investigate a fake Lupin calling card. Lupin shows up as well. Suddenly, masked assassins break in and begin to shoot everything that moves. Zenigata goes after Lupin amidst all the gunfire and corners him in the courtyard of the house. Suddenly, a hand holding a Walther P-38 pops out of a window and shoots Zenigata in the chest. Lupin recognizes the Walther as his own and decides to investigate. The assassins that attacked the party are from a hidden island called the Island of Assassins. The island is kept secret by the help of top government officials from around the world who use the assassins on the island for their own personal gains. There are lots of hidden secrets on the island, however, and Lupin, Goemon, Jigen, and Fujiko find themselves involved in a plot that tears the residents of the island in half. The movie also delves into Lupin's past in his pre-Jigen days.
