Marcus is a 14-year-old student who loves to fight and, in a way, considers himself to be an "ultimate fighter" . He lives with his mother Sarah and younger sister Kristy. Marcus meets and fights Agumon in the first episode of the series. When the fight ends in a draw, Agumon agrees to become his partner. Soon afterward, he's recruited as a member of DATS. Marcus is one of the few shown to fight Digimon by himself, though he still counts on Agumon's help to fight the stronger opponents. Even though others can evoke their DNA charges by themselves, Marcus must connect a punch on an enemy to do so, subsequently using it to digivolve Agumon.After the final battle he decides to stay in the digital world to help keep Digimon in-line.
Badass: What other word describes someone capable of punching out Digimon several hundred times his size?
Thomas is a 14-year-old boy genius who graduated from the Stockholm Royal University of Science at the age of 13. His abilities are considered élite, even within DATS. He bases his operations on data and theoretical principles, and as such his personality clashes with Marcus'. His mother is Japanese and his father is a prominent Austrian aristocrat named Franz Norstein. Franz and Thomas's mother met while she was an exchange student in Austria, and Thomas lived with his mother in Japan until she died. He was taken back to Austria. He also has a younger sister, Relena, who suffers from a strange disease. It is never shown who Relena's mother is, but she died of complications during childbirth. While Thomas does not particularly care for his cold father, he does love his sister very much and does whatever he can to protect her. Calm and shrewd, he is the exact opposite of Marcus and sees him as a rival. He has an elitist attitude but he gets emotional when thinking of his mother, who died years ago when he was young.
Badass Bookworm: He's a genius, but he's also Marcus' equal in a fight. Well it's kind of the other way around, everyon at DATS were impressed that Marcus tied with him and said he's beaten Olympic level fighters before.
Crazy-Prepared: In one of the early episodes, Masaru accidentally manages to wipe out a portion, if not all of DATS' database. Conveniently enough, Thomas just happens to have the entire database backed up on a flash-drive. He even says "I anticipated that something like this would happen, so I took a back-up".
Foreshadowing: His "crush" on Marcus's mother and sister hints at his issues with his own deceased mother and Ill Girl little sister. Gaomon also mentions in the first quarter of the series that Thomas is a licensed doctor—in a later episode, Thomas reveals that he's been studying medicine at such an accelerated rate specifically to cure his sister's illness.
Japanese Sibling Terminology: Weird case as Thomas is half-Japanese, half-Austrian. His half-sister, Relena, is fully Austrian. She addresses him with the very respectful "oniisama" in the Japanese version, but whether she's "actually" calling him that as an endearment or if it's the Translation Convention in effect isn't clarified. The dub adapts this by having Relena call Thomas "Tommy.")
At eighteen years of age, she is the oldest member of the group, compared to Marcus Damon who is fourteen years old and Thomas H. Norstein who is roughly the same age. Yoshino is independent and sees herself as an older sister figure to her two teammates. Despite her mature demeanor, she hides a terrible burden from her childhood and because of it, she has difficulty believing in her ability to do anything. When she was younger, Yoshino dealt with a severe inferiority complex that stemmed from being unable to be as good as her sisters at anything (the most noteworthy incident was a piano recital). As a result, years later, she still is secretly worried about being useless to anyone. Lalamon had been aware of her suffering for some time and helped her to overcome it. The fact became apparent when she started to feel she was useless to Marcus and Thomas since her Digimon was easily beaten in every single battle they took part in, but she eventually gained her own confidence, which allowed Lalamon to warp digivolve to Lilamon.
Image Song: Interestingly averted for Yoshino, as she is the only main character who never received an image song. This might be due to contract issues with Yui Aragaki, or because she was busy filming Waruboro and Tokyo Serendipity at the time.
As opposed to the other members of DATS, Keenan did not live in the human world, nor did he originally have a particular liking for it. Though originally born on Earth to the DATS scientists Kevin and Michelle Krier (Kenji and Misuzu Noguchi), he was accidentally transported to the Digital World as an infant. In the Digital World, he was raised by a Frigimon, who acted a a mother figure to him. Falcomon was raised alongside him like a brother. Following her death, he was raised by Merukimon, who became a father figure to him. He believes in defending the peace of the Digital World, and also believed that humans were nothing but a threat to it. Despite his young age, Keenan has great fighting skill (many of his moves mirror the ninja-like aspects of Falcomon). He wields a boomerang, and wears a cape and a necklace adorned with feathers, and also has facepaint.
And This Is for...: After Merukimon is killed by Kurata, he says this in regards to him before making Falcomon warp digivolve to Crowmon and curbstomp the Gizumon XT who killed Merukimon.
Boomerang Bigot: How appropriate, though it does not last too long once he realizes what he is, it still lasts long enough to qualify for this trope.
Charles Atlas Superpower: Lets not forget that this is a ten year old kid who, in most episodes is pulling stunts of strength and agility that would turn an Olympic Athlete green with envy. The best representation of this is the episode where he finally meets his parents and he carries his own mother out of their possessed house, making multi-story jumps the entire time. Once again, to reiterate, this kid is TEN YEARS OLD!
The Commander of DATS Japan, giving the three main members their orders. He also worked with Yushima as a private investigator, which led to them joining the expedition to the digital world and meeting Spencer Damon.
A mysterious old man who gave Marcus his Digivice and some advice several times throughout the series. Eventually revealed to be the chief officer of DATS and the partner of Kamemon, as well as a member of the first expedition to the Digital World.
The legacy of Dr. Spencer Damon is felt throughout the series, even though he does not appear in it personally at first. He is Marcus's father, and a member of the expedition to the Digital World. When the group was forced to escape back to the human world, he stayed behind to make sure they could escape, and for a while, it was unknown what happened to him. That is, until the answers were revealed by the Digimon called Mercurimon. Spencer had remained back in the Digital World in order to seek out the "god" of the Digital World named King Drasil. Before that, however, he created the Digivice, and sent the data for it to the human world along with Kudamon and Kamemon. After making a deal with Mercurimon to preserve the peace of both worlds, he departed. Over time, he was joined in his search by BanchoLeomon until they found King Drasil, but things went wrong and by the time Marcus and gang confronted King Drasil, it used Spencer's soulless body as its own. The soul of Spencer himself was taken in by BanchouLeomon at the last second when the Royal Knights advanced on them. However, thanks to his friend's sacrifice, Spencer was restored and King Drasil was purged from his body. Spencer returns to his family at the end of the last episode.
Living Legend: In the Digital world, Spenser Damon is nothing short of legendary; the mere mention of his name is enough to curry favor from the residents of the sacred city, as Marcus and the others found out.
Hotblooded/ Did You Just Punch Out Cthulhu?: It runs in the family, though Suguru isn't above resolving things peacefully before the punching starts. To get the whole point across, he beat Saber Leomon with his bare hands when the teams Digimon couldn't even scratch him.
Meaningful Name: 大門 (Dai Mon means "Great Gate" in Japanese, and he was a member of the first Digital World expedition.)
Science Hero: While his incredible strength served him well during his exploits in the Digital World, it's ultimately his scientific inventions that end up aiding the heroes the most during their journey.
A rather incompetent representative of the Confidentiality Ministry who oversees DATS.
Arrested for Heroism: Tries and fails to arrest Sampson for treason after the heroes return from the Digital World.
A character exclusive to the PS2 game Digimon World: Data Squad (Digimon Savers: Another Mission). She's Tsukasa's younger sister. She doesn't have any friends because she's friends with Digimon and they call her "monster girl". Yuma was one of the children kidnapped to power up the Demon Lords. Later on, she joins the team with her partner Renamon.
Agumon adores his partner Marcus, and considers himself to be "Marcus's employee". He even refers to Marcus as his Boss (though in the original Japanese he is referred to as aniki which is slang for bro... and what members of the Yakuza use to refer to their boss.) In the first episode, he is referred to by the code-name of Raptor-1 by DATS.His digivolutions are as follows:
In-Training: Koromon, a round, pink mon, with long ears, red eyes, and sharp teeth. Blows bubbles.
Rookie: Agumon, his default form. Note that he is different from his Digimon Adventure counterpart due to a pair of red wristbands on his hands and is considerably large.
Champion: GeoGreymon. Essentially Agumon, but proper dinosaur size, lots of spikes, a carapace on its head, and a massive fire attack.
Ultimate: RizeGreymon. GeoGreymon, with added mecha-armor, red hair, wings, and a giant revolverarm.
Mega: ShineGreymon. A winged knight-like dragon-themed warrior.
ShineGreymon Ruin Mode, a dark version of Burst Mode with black flames.
Burst Mode: ShineGreymon Turns Red and gains wings, a sword, and a shield made of fire.
Death Glare: After becoming ShineGreymon Burst Mode and easily blocking Kurata's attack, he gives one to Kurata while performing an Unflinching Walk slowly towards him. His expression can only be described as "I'm going to kill you".
Informed Ability: The Geo Grey Sword is supposed to be a powerful weapon when ShineGreymon first whips it out to defeat Bio Darkdramon. After that, it's sole purpose is to be pulled out, prove completely useless against the Monster of the Week and then tossed aside so that ShineGreymon's Burst Mode can do the real fighting.
"Sir, yes Sir!"Incredibly loyal to Thomas, Gaomon is the strong and quiet type, though he talks more in later episodes. He tends to blush when complimented. He almost always addresses Thomas as "Sir". He tends to be sarcastic towards Agumon.
Death of a Thousand Cuts: Forbidden temptation's description in the digimon dictionary would have you believe it is just a shower of rose petals but they just be very numerous and highly concentrated because it looks like a Kamehamehadoken and can beat back flames.
Faux Action Girl: Gets better as Yoshino does. Lampshaded in the "Tokuten Eizou" special (essentially a Clip Show with commentary from the main three Digimon), with both Agumon and Gaomon noting that Lalamon was basically useless before she became Lilamon.
Gainaxing: Rosemon, with more fanservice than the rest of the series combined.
Shipper on Deck: In episode 32 she as Rosemon, tries to get Yoshino to go on a date with Ivan to the mall.
Shout-Out/Expy: Sunflowmon resembles the Pokémon Sunflora, astonishingly enough, but what sells it is that her attack is Sunshine Beam. Which is pretty similar to Pokémon's Solarbeam.
Her evolution line is a parallel to the Palmon line, with Palmon and Togemon switching places (chubby plant-flower-fairy instead of flower-chubby plant-fairy). Unsurprising as both reach the same Mega form.
And additional shout out occurs in the twenty-minute "movie" in which Lalamon shows that she knows kung fu and proceeds to beat up mooks while doing Bruce Lee imitations and wielding nun-chucks made out of sausages.
Burst mode has a shout out to Rose Gundam's "rose fists".
Made of Iron: Crowmon resists the Gizumon attacks, perhaps explained by the Digimon dictionary which would have you believe its attacks work in a similar manner, which could explain its tolerance too them.
Ninja: Is it any wonder he and Keenan recruit Ninjamon later on?
Shout-Out: His Champion form is a techno variation on the traditional Japanese kappa water sprites. His Ultimate form is a shout out to Sha Wujing from Journey to the West. And finally, supplemental materials reveal that his Mega form is a shout out to Gamera.
Sarah is Marcus and Kristy's mother, as well as Spencer Damon's wife. While she first appeared, she reacted somewhat casually to Agumon's presence, it was eventually revealed that she had been knowledgeable of the existence of Digimon for some time. Though kind and supportive of her son, she is somewhat fearful when he voiced that he had to go to the Digital World and stop the machinations of Kurata. Her memories of the family's time with Agumon were temporarily erased, but that seems to have been reversed. She later appears to give the former DATS team dinner, and is very dumbfounded when meeting BanchoLeomon for the first time.
Open Minded Parent: Doesn't react particularly badly to the revelation of her son bringing home an extradimensional reptile. Of course, there's a reason for that...
Kristy is Marcus's sister. She was immediately taken with and friendly towards Marcus's rival and friend Thomas, and it was her wish that he escort her and her mother on her birthday. Later, Kristy befriended a newly hatched Digimon who eventually became Biyomon, but this relationship ended when Biyomon was struck down, and later driven to madness after being revived. When her friend was finally defeated, Kristy was happy to know her friend no longer had to suffer. He comes later back as her partner.
A cowardly scientist who used to work with Satsuma, Yushima, Suguru, and Ikuto's parents, and accompanied them on the first expedition into the Digital World. His experiences and activities there were less than positive. Several years later, he's somehow curried the favour of the politicians in charge of DATS and uses this influence to first accompany the team into the Digital World; then, when that doesn't go quite as planned, to convince the government that both Digimon and DATS are a threat and to have them wiped out and arrested respectively. Things continue to go pear-shaped from there. As the series goes on, he's shown to have no regard for human life either, and in fact his real plan with the data he took from the Digital World was to revive a powerful digimon called Belphemon and use him to Take Over the World.
Dirty Coward: He's a genocidal monster, but when the tables turn on him, he reacts with complete fear. In the end he responds by begging ShineGreymon Burst Mode to stay back and begs for his life and then asking for someone to save him before he gets vaporized.
In fact, out of all the anime and manga of Digimon, he's the only genuinely evil human antagonist - Oikawa and Ken were controlled/influenced by Myotismon, respectively, and Neo Saiba was manipulated by Daemon.
Humiliation Conga: After ShineGreymon evolves to Burst Mode, the fight becomes this for him. First, ShineGreymon preceeds to literally tear his One-Winged Angel form apart around him and shrugs off his counterattack like it was nothing. His dialog after that consists almost entirely of begging for his life as he's soundly defeated in one punch. To add insult to injury, his attempt to destroy the Digital World with his dying breath backfires and results in his death as he's screaming for someone to save him. Sure, that did set up the next arc, but he didn't know that, his last memories are being vaporised by his own revenge plot while dying as he lived as a scared, pathetic man. Due to him being the most evil Digimon villain ever, his downfall is extremely satisfying.
Hypocrite: Okay Kurata, you hate Digimon. So how come so many of your plans and experiments rely on Digimon, your three lackeys can transform into Digimon, and you even merge with a Digimon! Shouldn't you not be able to stand it? Thomas even calls him on this!
He's much worse than that; he believes digimon are dangerous beasts because a Lynxmon had previously attacked him, except that the audience can see that the digimon had only attacked him after he had shot at it. Additionally Kurata reveals that he had invaded and committed genocide on the Digital world which meant a LOT of permanent deaths, among them Keenan's adoptive mother, while accusing the Digimon of eventually attacking the Real World due to their vicious nature!
He never cared about the damage done by Digimon, he always had plans to use Belphemon to rule the human world, who coincidentally does more damage in his rampage than all the earlier Digimon COMBINED. Really, his attitude can be summed up as It's All About Me.
Karmic Death: And how! Although unfortunately, his action that accidentally caused his own death also had some terribleunforeseenconsequences as well. Still doesn't change the fact he got exactly what he deserved though.
Jerkass Has a Point: Yes, his actions are nothing short of vile, by all standards. Given that there are countless Digimon out to cause death and destruction, as most other seasons prove by having Digimon-villains, chief amongst whom, the Demon Lords, he makes a rather good case that humanity ought to be able to defend itself.
Oh Crap: His reaction to ShineGreymon Burst Mode. His Oh Craps get progressively larger as ShineGreymon shrugs off his counterattack like it was nothing, shoots him an absolutely hate-filled Death Glare while performing an Unflinching Walk straight towards him, and finally when Marcus prepares to punch his face in. His biggest one, however, comes when his final plan fails to destroy the Digital World as he'd wanted and he's killed in the resulting reaction.
Omnicidal Maniac: He wishes to kill all Digimon. There's a reason fans consider him worse than Myotismon...
This was his initial goal but he eventually changes his mind when he realizes Digimon can be controlled. He still keeps up the act however as part of his bid to get the government on his side, who end up funding his Take Over the Worldscheme.
One-Winged Angel: Merges with Belphemon to become Belphemon Rage Mode, his face appearing in its chest.
Scaled Up: Works most of the time too but is eventually left behind
Snakes Are Evil: Her form is ironically based off an aversion to the trope.
Teen Genius: Revealed to be one in the episode where she fights Thomas.
The Paralyzer: As BioQuetzalmon by squeezing the opponent(she is a snake in that form)
Victorious Loser: Thomas wins the fight, but she definitely gets the last laugh.
Voiced by: Takanori Hoshino (JP)
Ambiguous Disorder: Between his tendency to say what he's thinking (while being utterly oblivious to it) and his general dim-witted behaviour, it's tempting to say he has some kind of disorder, but it's hard to say what it is.
Anti-Villain: Type III. The guy is only trying to protect the Digimon and Kurata tried to genocide them, it's only natural he'd come to think Humans Are the Real Monsters. That and the two worlds are about to collide and from his perspective due to Kurata's actions, destroying the human world is the best option.
Big Bad: Of the final arc. However, Kurata is still directly responsable for this and the overall Big Bad of the series, so King Drasil is actually just the Final Boss.
Famous Last Words: "Very well then... I shall lay myself to rest and protect you from afar without any further meddling. I don't know if a world can exist where humans and Digimon live together in harmony. But if it is to become a reality, then it will be completely up to you."
Noble Demon: Craniamon. He tried to persuade Drasil to forgo his plan to destroy the Human world at first. Though he would agree to Drasil's plan, he maintains an open mind and is able to gracefully accept defeat when his opponent has proven their strength.
