After the events of 02, everything is finally getting back to normal. That is, until a strangely familiar icon starts showing up on computer systems around the Japan. And not just computer systems... TVs, mobile phones, video games; anything with a screen with online capabilities. And this icon seems to be looking for somone... Yagami Taichi, and Ishida Yamato, who defeated it several years before. Yes, it turns out that this jellyfish digimon is in fact Diablomon, the Virus-type Digimon that was defeated in the second movie. But this time, he's learned to make himself physical, and is sending thousands of copies of himself into the real world. Koushiro and Ken devise a plan to rid the world of the virus once and for all, but it'll take the help of all the Destined, past and present. Once again, it's a race against time to put a stop to Diablomon's plot... but even that is cloaked in shadow. Will the revival of Omegamon be enough to stop Diablomon a second time, or will the millions of copies prove enough of a power boost to shrug off the Digimon Champion of Justice? Of course, he hasn't seen the new breed of Chosen, nor the new techniques. It's a fight to the finish, with the destruction of Tokyo resting on the line. (Source: AniDB)

Bakugan Interspace is a virtual reality system, where players can brawl against each other and take part in tournaments. Initially designed to help practice and enhance Bakugan skills, it quickly became a meeting place for many enthusiasts. During one of Danma Kuusou's duels, the Interspace crashes, and he gets knocked out cold. Before regaining consciousness, he experiences a vision of Bakugan at war with each other once again. The explosion of energy that accompanied Danma's fight and caused the shutdown of the system sends shock waves across the galaxy, attracting the attention of the Twelve Orders, a Gundalian organization. They infiltrate Bakugan Interspace, looking for strong brawlers to join them in their upcoming war with another alien race, the Neathians. Danma and his companions—Shun Kazami and Chouji Marukura—soon find themselves caught up in an extraterrestrial war. However, distant as it may seem, the conflict threatens the very sovereignty of Earth and the future of the Bakugan race as well.

When Yun Arikawa and his partner, Haberu Katou, investigate a house rumored to be haunted, the last thing they expect is to stumble into a mystery that will soon envelop the entire planet. While measuring strange radio signals, they receive a call from Mei Kamino, a graduate student investigating the same signal and using the equipment their company previously installed. After an odd night, Yun returns to work at Ootaki Factory, a tech company that actually exists to produce Jet Jaguar—a robot that conspiracy theorist Gorou Ootaki has dreamed of creating. However, when flying dinosaur-like creatures known as Rodan are attracted to the strange radio signals, Jet Jaguar seems to be the only force capable of fighting them. As Yun and Mei investigate the Rodans' sudden appearance, more dangerous monsters begin to surface from the ocean—along with enigmatic red dust.

The compilation film will recap the anime's 59 episodes from seasons one to three.
