Story
<!--rewrite in-universe, with correct grammar and storylinks

A 14-year-old boy, Marcus Damon, an undefeated ultimate fighter (street fighter in the original Japanese version), meets Agumon, who has escaped from the Digital Accident Tactics Squad (DATS), a secret government organization set up to defend the human world from invading wild Digimon. After fighting each other, the two quickly become friends, and through a series of events, are inducted into DATS, where they hope to grow in strength.

Marcus' team-mates include the 14-year-old Thomas H. Norstein, a young prodigy, with his partner Gaomon, and 18-year-old Yoshino "Yoshi" Fujieda who has Lalamon for her partner. As the series progresses, Thomas discovers that Digimon respond to the "darkness" in humans, putting them at odds with monsters who seek to use humanity's own vices to bolster their own power.

The plot thickens with the introduction of Merukimon, one of the rulers (as a member of the Olympus Twelve, Merukimon has a god status in the Digital World), of the Digital World who rules the eastern Digital World and lives in the Infinite Ice Ridge, Biyomon and the human boy Keenan Crier, who serves him along with his partner Falcomon. The DATS team tries to unfold the reason for their hatred of humankind, until it is revealed that the real enemy was Akihiro Kurata, a scientist who led an attack on the Digital World years before that resulted in the death of many Digimon, including Keenan's adoptive mother, Frigimon.

Kurata gained the support of the Japanese government and important businessmen like Thomas' father on his plan to destroy all Digimon in the Digital World, claiming they were a threat to mankind. But this was only a facade to occult his main objective. He harnesses the energy of the Digimon he destroyed to power-up Belphemon, one of the Seven Deadly Digimon/Seven Great Demon Lords, and uses it in his attempt to rule the Human World (and eventually the Digital World), but his ambitions were shattered by the efforts of Marcus and his allies.

Kurata's last act was triggering a bomb which collapsed the frontier between the Human and Digital Worlds, putting both en route on collision, which could have led to the destruction of both realms. The collision was halted by the desperate efforts of BanchoLeomon who ordered Marcus to search for Yggdrasil/King Drasil, the Supreme Ruler and God of the Digital World. When the DATS team finally met King Drasil, they discovered that his decision to deal with the crisis unfolded, was to protect the Digital World by destroying the Human World, as the two worlds could not coexist in the same dimension. To perform this task, he assembled his elite guard, the Royal Knights.

Marcus was confused at first because King Drasil somehow had the appearance of his father, Dr. Spencer Damon, who disappeared in the Digital World years before. But it was revealed that King Drasil took his father's body, and his soul was somehow preserved by BanchoLeomon, who was revealed to be Spencer's partner Digimon. After defeating some of the Royal Knights, the DATS team decided to confront King Drasil himself, who after being expelled from Spencer's body, transformed himself into an all-powerful robotic form determined to destroy the Human World by itself.

However, even when the Royal Knights rebel against King Drasil, it won't give up its goal, attempting to destroy both worlds and create a new world. Using their emotions, Marcus and Agumon finally defeat King Drasil, and the two worlds cease their collision course. Before disappearing, King Drasil brings Spencer back to life and he returns to his family, but the Digimon decide to return to the Digital World to help restore it, and in the end Marcus decides to not part with Agumon and goes with them.

It should be noted of Marcus's importance to the team: he is often the one to finish a major opponent. Some examples are when he smashed SaberLeomon's fang, blasting his DNA through 's chest, destroying Craniamon's shield and shattering Yggdrasill's true form. These are all performed from when he punches the opponent with immense strength.

Marcus's DNA Charge seems to possess great potential: the most noticeable moment was in episode 45 when his revelation that his friends believed and trusted him to stop King Drasil/Spencer Damon, it created an aura that protected him from MirageGaogamon's Full Moon Blaster and Rosemon's Forbidden Temptation; instead of hurting him, it simply collided with the aura and propelled Marcus upwards (he had been falling at the time). --> Many years ago, his father Spencer Damon leaves alongside and DATS members to explore the Digiworld, leaving Sarah to fend for herself with his sister Kristy.

In the present day, he accidentally met Agumon while the latter are lost in Human World, annoyed by the Digimon's wild nature, he fights it by fists, which ended in a draw and drawing admiration by the Digimon, calling him 'Big Brother'. Agumon follows him anywhere, even in his own house, shocking his mother, but accepts the Digimon in her home, despite his protests.

He became a member of DATS after meeting Yoshino "Yoshi" Fujieda and Thomas H. Norstein alongside their respective Digimon and forms an unstable team, with him and Thomas bickering among themselves, but united when facing challenges.

later hatches his vile plan, eliminating Digimon by deleting their data, and blackmailing Thomas into collaborating for him by he has the only cure for his sister's sickness. He later defeats Kurata merged with a after reunited with his partner, who reverts into a DigiEgg after using its life force out of rage upon Norstein's betrayal, but retains Agumon's memory.

After defeating Kurata, he alongside Yoshino and Thomas must return to Digiworld to confront King Drasil for his actions, and to find his father. He later found his father held captive by Drasil. When the portal to Human World is closing, he saves his father and the rest of the human members of DATS, decided to stay in Digiworld with Agumon.

Five years later, he and Agumon still wander the Digital World, challenging strong Digimon and settling rival disputes with fists and his partner Agumon.
