Digimon Savers

In the world we all know, there exists a secret organization called the Digimon Data Squad, or DATS for short. Humans and their tamed Digimon partners team up to capture Digimon who cross over into the real world from the Digital World (hopefully, before the population sees them and causes a panic). Secret Agent Yoshino Fujieda gets a call to chase down a rogue Raptor Digimon, but she finds him engaging a human in a fight. The human is a boy training to become an Ultimate Fighter, Marcus Damon. Amazingly, Marcus can hold his own with the supposedly much stronger Digimon. After they fight to a draw, the two combatants bond, and then flee together when Yoshi tries to arrest them. Marcus hides the raptor, named Agumon, and goes to get him food. But Yoshi finds Marcus, and takes him to DATS headquarters. Marcus doesn't believe that Agumon could be a danger, so he refuses to turn him over. But, suddenly, there is another Digimon attack in the city! Marcus rushes back to see if Agumon could really be leading the attack, as DATS suspects. Marcus finds Agumon blameless. The attack is the work of another Digimon invader, Kokatorimon. Marcus and Agumon battle the giant bird together. Marcus discovers that when he gets emotional in battle, he can awaken something in his fist known as the DNA. A mysterious stranger gives Marcus a digivice and tells him that with his DNA, he can help Agumon digivolve into a bigger, stronger form. He does, and Agumon becomes GeoGreymon, and he defeats Kokatorimon.

Yoshino brings Marcus and Agumon into DATS headquarters so Agumon can be sent back to the Digital World. Luckily, they manage to escape. Marcus takes Agumon home and tries to keep him hidden from his mom, Sara, and sister, Kristy. But Agumon is hard to keep a secret and they soon find out about him and make him feel right at home. Yoshino shows up to recapture Agumon and erase the family's memory, but Commander Sampson tells her there's a change of plans - Yoshino will now just keep an eye on Marcus and Agumon. Yoshino follows Marcus when he heads to school, toting Agumon along in his Digivice, but a disturbance at Kristy's school sidetracks them all. Someone has broken into the school's animal pens. Yoshino is sure that it was a Digimon. Marcus uses Agumon as bait to attract the rogue Digimon. Sure enough, Dokunemon returns to the schoolyard that very night! Yoshino and Lalamon battle the Digimon but lose. Unable to just standy by, Marcus and Agumon step in and take down Dokunemon themselves. The rogue Digimon is sent back to the Digital World in egg form. Marcus and Agumon decide to offer their services as DATS agents, in part so that Agumon won't have to be sent back to the Digital World, and also because Marcus sees their missions as another way for him to become the Ultimate Fighter. To Yoshino's surprise, Commander Sampson accepts their offer. Meanwhile, in another part of the world, Thomas H. Norstein and his Digimon, Gaomon are flying back home.

Demimeramon shows up in the human world, spreading fire and creating havoc. Marcus and Agumon try to fight him, but Agumon's fire attacks do nothing and Marcus' punches go right through him. Demimeramon easily escapes them. But Thomas Norstein and his Digimon, Gaomon show up and get the job done flawlessly. Thomas is not only of royal descent, but a genius who has been away on another DATS assignment. Marcus is quickly threatened by Thomas and the two square off. Thomas tells Sampson that he believes Marcus has no place in DATS. Marcus challenges Thomas to a fight in the boxing ring, and is initially defeated. But Marcus doesn't give up and fights to a draw. Suddenly, Demimeramon is back and has multiplied several times over. Thomas is dispatched to deal with the problem leaving Marcus to brood. But as Marcus walks off his anger, he begins to realize he may not be as great a fighter as he thought he was. He runs into the old man again, who teaches him a lesson about perseverance, and fighting fire with fire as an example. Just then more Demimeramon attack again, but Thomas is too far away to do battle. Marcus defies orders and confronts the threat himself. Since he can't land a punch against Demimeramon, he forces him to digivolve into Meramon. Then he hits him with his fist and activates his DNA! Agumon digivolves to Geogreymon and defeats Meramon. Back at DATS, Sampson has had enough of the Marcus and Thomas fighting. He makes the two work together as a team from now on.

The Digimon Data Squad is in hot pursuit of a rogue Digimon named Numemon. As usual, Marcus and Thomas are busy following their separate battle plans. When they bungle the assignment, Yoshino and Lalamon have to step in to bring Numemon down – all the way down to his Digi-egg form. Marcus and Thomas blame each other for their problems, and tempers flare. Meanwhile, two burglars break into a bank, and the device they use to override security attracts Drimogemon. The burglars quickly befriend Drimogemon and get the conveniently, drill-nosed Digimon to help them rob an ATM. DATS moves in! Marcus, Agumon, Thomas, and Gaomon battle Drimogemon while Yoshino and Lalamon take care of the burglars. Marcus and Thomas keep getting in each other's way because they can't — or won't — work as a team, so Drimogemon gets away. Commander Sampson takes them to task for their failure, but he remains adamant that Marcus and Thomas remain partners. Thomas asks to use the Digital Dive to go to the Digital World and prevent Drimogemon from returning to interfere in the human world. Sampson thinks that it's too dangerous and refuses the request. Later that evening, Thomas sneaks into DATS headquarters. Defying Sampson’s orders, he activates the Digital Dive and transports himself and Gaomon to the Digital World!

Moments after Thomas defies Sampson's orders and transports himself and Gaomon to the Digital World, Marcus sneaks into DATS, too. With no one else at headquarters, Marcus threatens to break the Digital Dive machine unless Yoshi helps him go to the Digital World to finish his fight with Drimogemon. She grudgingly helps Marcus with his Digital Dive, but only so he and Agumon can bring back Thomas and Gaomon. In the Digital World, Marcus and Agumon soon come face to face with Drimogemon again. Drimogemon easily traps them underground, and they are reunited with an injured Thomas and Gaomon. They were also outmaneuvered by the drilling Digimon. Thomas reluctantly accepts Marcus' help to find their way out the underground den and defeat Drimogemon. The foursome find Drimogemon. Instead of waiting until they're at an advantage above ground, Marcus attacks! He forces Drimogemon to the surface, riding him like a bucking bronco. Then he steers him to an ice arena, where he can't dig to escape. Geogreymon and Gaogamon combine their attack spells and defeat Drimogemon, who had digivolved to Digmon. Back at DATS, Sampson scolds Marcus and Thomas, but is relieved they are safely home.

Marcus and Agumon fight and defeat Tortomon, but Yoshino takes them to task for rushing into battle on their own. Marcus and Agumon remain confident in their ability to defeat whatever foe they face, even if they face it alone. Their bond doesn't last long - they soon get into a silly argument and then refuse to work together anymore. Agumon sulks in his Digivice. Marcus gets into a street fight with an old, human rival and his cronies. When Elecmon appears, Marcus goes after it himself. Realizing Marucs is useless without Agumon, Thomas, Gaomon, Yoshino, and Lalamon move in to help. But Marcus stubbornly insists on fighting Elecmon alone, even when it digivolves into Garurumon. Marcus leaps on the Digimon's back, and it runs off. Marcus recklessly fights Garurumon, until he realizes that it's too big a task for one person. Luckily, Agumon shows up to help him, and together, they defeat Garurumon. The Ultimate Team is reunited!
