- "It's fighting time!"/"That's how a man lives!"
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.
- 10-Minute Retirement: After ShineGreymon Ruin Mode's rampage made Agumon turn back into a digiegg, he's forced to stay with his mom and sister after the others go fight against Belphemon but he later decides to go fight with them even without Agumon.
- 11th-Hour Superpower: His bond with Agumon helps him achieve his own Burst Mode which they use it to finish off Yggdrasil.
- Achilles in His Tent: Against his will but because Agumon was a Digiegg, he couldn't join the others against Belphemon. Eventually, he went to the fight with him still as a Digiegg.
- All-Loving Hero: Masaru picks up where his father Suguru left off as far as reaching out to Digimon and trying to create the world where Digimon and humans can live together.
- And This Is for...: A dark version of this trope, when ShineGreymon Ruin Mode is pummeling MirageGaogamon, he says this about the Digimon that died because of Kurata and that Tohma will apologize to them with his life.
- A more heroic version happens later on the series, even though he doesn't say it himself, when he has Kurata at his mercy, his friends tell him to deal the killing blow for all Digimon that Kurata has killed. Masaru and ShineGreymon Burst Mode are happy to oblige.
- Awesome Mccoolname
- Badass Baritone: He has a deep growling voice which goes well with his Hot-Blooded Blood Knight personality.
- Badass Family: He and his father, Suguru, both we're able to fight fairly against Mega level Digimon.
- Badass Normal: He's strong and beat up several men at the beggining of the series. He even tied against Tohma, even though he's had far more formal training than Masaru.
- Bash Brothers: In traditional Digimon fashion, he's this with Tohma but because he's the first human Digimon protagonist that's also capable of fighting against Digimons. He fits this with Agumon, as well
- Battle Aura: His DigiSoul becomes a orange aura before he digivolves Agumon to Perfect level onwards, his rage at Tohma's betrayal turns it into a dark purple color however.
- Beyond the Impossible: He breaks an unbreakable shield with his bare fist.
- Bicep-Polishing Gesture: Done as early as episode 6.
- Big Brother Instinct: His greatest fear is not being able to rescue his sister. He also develops this with Keenan, offering to let him live in his house.
- Big Damn Heroes: He arrives just in time after all his friends have been defeated by Dukemon and digivolves Agumon to ShineGreymon to fight. Unfortunely, they also lose and have to be saved by Satsuma and Sleipmon.
- Big Eater: Best exemplified in episode 22, where his rice bowl towers everyone else's and then he asks for additional rice several scenes later.
- The Big Guy: His primary strategy is to get in close and punch the shit out of the enemy. In fact, doing so is the only way he can generate a DNA charge to digivolve Agumon.
- Blood Knight: He refers to himself as the "number one street fighter" and thus never turns down a challenge from any human or Digimon and always enjoys a good fight.
- Book Dumb: Though he lacks Tohma's intelligence, Masaru is smarter than he may seem.
- Catch Phrase:
- "It's fighting time!" in the dub.
- "That's how a man lives!" in the original.
- Charles Atlas Superpower: The strength of Masaru's punches things scales with the drama of the series, often improbably so.
- Cooldown Hug: He get's one from Chika after he orders ShineGreymon Ruin Mode to kill Tohma. While it did calm him down, it did nothing to stop ShineGreymon Ruin Mode's rampage.
- Crossdressing Voices: Notably averts this, being the only Digimon lead protagonist to (in the Japanese versions) have never been voiced by a female voice actress outside of flashback.
- Dead Sidekick: Agumon gets a Disney Death at some point. He gets better, despite Marcus being told he'd lose his memory.
- Delinquents: A banchou in the original.
- Determinator: Especially notable when he was the only one that didn't lose hope after Tohma explained the damage Belphemon would cause to both the Earth and the Digital World, and instead he said that they should just hurry up and beat him. This is what inspires the others in continuing the fight."Ever since the beginning, I knew there would be trouble. But what we have to do... hasn't changed a bit!"
- Did You Just Punch Out Cthulhu?: His trademark; nearly every time Agumon needs to digivolve will result in this. And a literal example, as he often literally punches them out.
- Four-Temperament Ensemble: The Choleric
- Goggles Do Nothing: It is such a recognizable image in this franchise that it should be noted that he averts this.
- The Hero
- Hidden Depths: Best shown when he asked for Tohma to look after his mom and sister during the latter's birthday because he has a test to do. Tohma at first assumed that Masaru wanted Tohma to do the test for him but Masaru was quick to say that he'd never ask that.
- Hot-Blooded: Extremely. If he didn't have his partner, he'd probably just keep punching his enemies until he got himself killed.
- I Choose to Stay: After the final battle he decides to stay in the digital world to help keep Digimon in-line.
- Idiot Hero: Okay, he's not an idiot per se, but he never thinks things through.
- Image Song: Beater! and Yume No Kakera
- I Should Have Been Better: After Chika tearfully asks him if Biyomon truly doesn't remember her anymore, Masaru feels this way. Saying his power wasn't useful at all to protect Chika and Biyomon's feelings and wishing to be stronger so no one else will have to suffer painful emotions. This feeling and willpower allows him to reach a new Digisoul and evolve GeoGreymon to RizeGreymon
- Jerk with a Heart of Gold: He can be quite the jerk at times, especially to Tohma, and isn't above arguing and even fighting with Agumon but he definitely has a good heart and is a loyal friend even to Tohma, who he had serious trouble working together with at first, and Ikuto, who has attacked him a lot of times.
- The McCoy
- Manly Tears: Anytime he cries, it's guaranteed to be this.Agumon: Aniki, are you crying?
Masaru: No! You idiot! These are sweat drops from my heart!
- Meaningful Name: Can be read as "daimondai", which sounds like "big problem".
- Muscles Are Meaningless: Despite his Younger Than He Looks appearance and penchant for getting into physical fights he theoretically shouldn't be able to win and actually winning them, Marcus is shown to be rather skinny, and coupled with his height, can come off as positively lanky in the right/wrong clothes (like his school uniform, which looks too big for him). This is a trait he shares with his father. The Distant Finale that takes place five years later, however, does show him sporting a bit of muscle.
- My God, What Have I Done?: His reaction to ShineGreymon Burst Mode's rampage followed by Agumon's Disney Death due to the fact it happened after his anger at Tohma forced the digievolution.
- Primary-Color Champion: Marcus's civilian wear in earlier episodes consists of a red unbuttoned shirt over a white shirt, blue jeans and red sneakers. His version of the DATS uniform in a blue jacket over a red jumpsuit.
- Rated M for Manly: How else can you describe a guy that punches Mega level Digimon in the face?
- Red Oni, Blue Oni: The red to Tohma's blue. Tohma is a brilliant tactician who's a trained fighter and keeps a calm head. Masaru charges in a hits things until they stop being a problem.
- Rookie Red Ranger: While he is the Red Ranger equivalent for a Digimon Series, he is not the leader of DATS, nor is he the leader of his small group.
- Strong Family Resemblance: Masaru only inherited his mother's auburn hair. He gained everything else from his father.
- Talk to the Fist: Several occasions but the most impressive one was definitely when against Kurata.
- This Is Unforgivable!: He says this a lot, especially to Kurata. But one example that stands out is the one says after Tohma's FaceHeel Turn.Masaru: Unforgivable... Tohma... You are completely unforgivable!
- True Companions: Agumon, later with Tohma, Yoshino, and Ikuto.
- Unskilled, but Strong: Strong enough to punch out digimon many times his size, despite lacking the formal training that Tohma has.
- Unstoppable Rage: After Tohma's betrayal, Masaru was left so furious that his rage was enough to digivolve ShineGreymon into it's Ruin Mode and he kept screaming for him to mercilessly attack MirageGaogamon and was actually aiming to kill him! It took Chika begging him to stop for him to snap out of it.
- World's Strongest Man: No doubt about it, Masaru is probably THE strongest human shown in the series yet, he has used his DigiSoul to punch several Digimon and has even knocked them down!
- Younger Than They Look: Sure, he looks more like his age in a school uniform... but out of it, it's hard to believe he's only 14.

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.
- Attack Pattern Alpha: He has lots of them with Gaomon and his evolutions. The attack patterns even work for the newly-acquired MirageGaogamon Burst Mode, as demonstrated in episode 42.
- Badass Baritone: Has one (for his age, anyway- he's only 14) in the English dub, courtesy of Crispin Freeman.
- Badass Bookworm: He's a genius, but he's also Marcus's equal in a fight. Well it's kind of the other way around, everyone at DATS were impressed that Marcus tied with him and said he's beaten Olympic level fighters before.
- Big Brother Instinct: Towards his half-sister, Relena
- But Not Too Foreign: Half-Austrian
- 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".
- Fake Defector: He only did so in order to remove the bomb that was placed on Relena's neck.
- Foe Romance Subtext: With Nanami, and how.
- 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.
- Heroic Bastard: His parents met when his mother was an exchange student studying in Austria. And judging by his grandmother's words, they had him by accident.
- Image Song: "Cool Running"
- Improbable Age: He's a 14 year old Teen Genius who's already graduated from college.
- The Lancer: His debut episode had his and Masaru's personalities clashing a lot which resulted in them getting into a lot of arguments. They learn to respect each other as the series goes on but their arguments persist throught the entire series.
- Missing Mom: His mother is dead, having been hit by a truck when he was younger.
- Mysterious Middle Initial: We never do find out what the "H" stands for...
- Naked on Arrival: In the Japanese version, he's first formally introduced in the shower. You're welcome, ladies.
- Omniglot: Knows 170 languages from around the world, according to Gaomon.
- Punch Catch: Had a few with Masaru.
- Red Oni, Blue Oni: The blue to Masaru' red. Tohma is a brilliant tactician who's a trained fighter and keeps a calm head. Masaru charges in a hits things until they stop being a problem.
- Spell My Name with an "S": His Japanese name. Is it "Touma", "Tohma", "Toma", or "Tooma"? The dub settled with "Thomas".
- Teen Genius: As mentioned, he graduated from Stockholm Royal University of Science at the age of 13
- Younger Than They Look: He's supposed to be 14 years old, but he looks at least 4 years older than his designated age.

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.
- Catch Phrase: "This is the worst!" is a recurring phrase Yoshino says. It's also a case of Throw It In! — the catchphrase originated from Mari Yaguchi from Hello! Project, and after Ryouta Yamaguchi heard Yoshino's voice actress, Yui Aragaki, repeat it several times, he decided to include it in the show.
- Cool Big Sis: She thinks she's this, but Lalamon disagrees.
- Curtains Match the Window: Her eyes are the same reddish-brown color as her hair.
- Distressed Damsel: Despite having experience as a field operator, Yoshino is usually the one who gets trapped or falls first during missions, making her more of a Faux Action Girl. Examples include losing her debut fight, and being the only one who gets sick during the mission in the Digital World. By the second arc arrives, she Took a Level in Badass however.
- Drives Like Crazy: Though in her defense, when she actually drives like crazy, the car was chased by attacking Digimon or government's officials.
- Fair Cop: Becomes one in the epilogue.
- Fiery Redhead: Slowly turns into one during the course of the series. In Kudamon's words, she's becoming more and more like Marcus on each passing days.
- 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.
- Incredibly Obvious Tail: She makes no effort to hide that she is following Marcus and Agumon at first.
- Older Than They Look: Because she's shorter than Marcus and Thomas, one can be forgiven for assuming that she's on the same age as those two. She's actually four years older than them.
- Overshadowed by Awesome: Compared to super-strong Marcus, Teen Genius Thomas, and Wild Child Keenan, Yoshi comes off as a rather ordinary person. Her realizing that there are some things that only she can do that the others cannot is pivotal to her Character Development and Sunflowmon's evolution to Lilamon.
- The Smurfette Principle: Of the human half of the team.
- Team Mom: In episode 43, where she tries to be one for the stranded baby Digimons in the Damon household.
- Throw a Barrel at It: Does so in episode 32, where she attacks a Gizumon-XT that was peeking through the window by throwing a barrel at it.

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.
- Battle Boomerang: Has two, with the second being the first's replacement after it got smashed into data by Marcus.
- 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!
- Cute Bruiser: A little boy who is A LOT stronger than he looks.
- Et Tu, Brute?: Not all Digimon were as loyal to him as he was to them.
- HeelFace Turn: A less extreme case compared to the others in Digimon franchise, since he never did any villainous acts beyond his fights against Marcus. His hatred towards humanity was what keeping him from fully turning in, until Merukimon conviced him otherwise in episode 25.
- Hulk Speak: Strangely enough, even though Digimon usually speak normally, so being raised by them really shouldn't have affected his speech pattern. He gets better by the end of the show.
- Last-Name Basis: In the localized version of Digimon World Data Squad and Digimon World Dawn/Dusk, where everyone calls him "Crier".
- Let's You and Him Fight: Keenan vs. other humans, until...
- Missing Mom: His foster mother was murdered by Akihiro Kurata.
- Oblivious Adoption: He was raised by a Frigimon but never seemed to make the connection considering he's not himself a digimon.
- Raised by Wolves: He was raised by digimon.
- Ship Tease: With Kristy.
- Sixth Ranger: He's the last member to join DATS and his partner is the only one who can achieve Burst Mode like the other three protagonists.
- Weapon of Choice: His boomerang he's rarely seen without.
- Would Hit a Girl: He almost succeeded on attacking a defenseless, bed-ridden Yoshi in episode 16. Thankfully, Marcus arrived just in time.
- You Gotta Have Blue Hair: His is dark blue.

Megumi voiced by: Yukiko Hanioka (JP), Stephanie Sheh (EN), Carolina Tak (Spain), Karina Altamirano (Latin America)
The computer operators at DATS, who generally give data on the digimon the team is facing. After the final battle, they become police officers.
- Bridge Bunnies: Their job in DATS.
- Calling Your Attacks: The girls have to call the attacks for their PawnChessmon, who are mute.
- Color-Coded for Your Convenience: Amusingly subverted in their second wardrobe. Megumi wears mostly black even though her PawnChessmon is white, and the reverse applies to Miki as well. The two even can use each other's Digivices, which are colored in inverse of their respective surnames.
- Expy: Of Reika and Megumi of Tamers, to the point of Reika and Miki sharing a voice actress (Ai Nagano) and the other two sharing a first name (Megumi).
- Let's Get Dangerous!: Whenever they get off the bridge.

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.
- Badass Baritone: Commanding and damn scary when he raises his voice. Yoshino (and merchandise) even mention his nickname as "Oni no Ikkatsu". (lit. 'The Demon's Thunderous Roar')
- The Captain: The leader of DATS.
- Cool Shades: Never once takes them off. Ever. Not even in the dark. Lampshaded further when you view his model from the Digimon Masters Online MMORPG: If you look behind his shades, his eyes are closed!
- Da Chief: The team (and us viewers) found out the hard way how loud he is when you screw up royally. Used for comedic effect in Episode 20.
- Heroic Sacrifice: At least in intent, though it didn't result in his death. He was out of the way for quite a while, though.
- Let's Get Dangerous!: He follows the Bio Hybrids into the Digital Gate and has Kudamon jump straight to the Ultimate Level so as to buy the others time to get away, with them able to keep the Hybrids in a stalemate despite being outnumbered.
- The Stoic: Even when issuing orders, very little emotion besides authority drips out.
Voiced by: Cho (JP), Kirk Thornton (EN), Rafael Calvo (Spain), Mario Hernández (Latin America)
- Cool Old Guy: While he is the Chief Officer, he's perfectly fine with just chilling and fishing, while also handing out Digivices to those like Marcus that catch his eye.
- Intergenerational Friendship: With the rest of the cast, though he develops one with Relena later on.
- Stealth Mentor: To Marcus during the first arc of the series.

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.
- Badass Normal: He was recruited into the original Digital World exploration team due to his scientific knowledge, and he was the original designer of the Digivice. He survived in the Digital World with his bare hands and the power of Digisoul/DNA charge.
- Badass Bookworm: For reasons stated above. He also contended with badass Banchou Leomon, arguably one of the MOST Badass Digimon, EVER.
- Demonic Possession: His body was taken by Yggdrasil/King Drasil sometime before his reunion with his son.
- Disappeared Dad: He's this to Masaru.
- Famed in Story: 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.
- Genius Bruiser: He's as intelligent as he is strong. And he is VERY strong.
- Hot-Blooded: 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 SaberLeomon 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.)
- Mysterious Parent: TO Masaru.
- 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.
- Head-in-the-Sand Management: He gives Kurata everything he asks for.
- The Masquerade: He's supposed to make sure that DATS maintains it and threatens to disband them after Merukimon shows up.
- Oh, Crap!: When Kurata inevitably betrays him.
- Distressed Damsel: At first.
- Evil Laugh: He breaks into one when assuming being the Big Bad.
- Expy: His appearance, his fascination of a specific subject of Digimon, his Evil Plan involving Demon Lords, his overall motivation being It's All About Me, and him being envious of a fellow scientist, all point at him being the game's version of Kurata.
- Foreshadowing: The best specialist regarding the Dark Area.

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 revolver arm.
- 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.
- Accessory-Wearing Cartoon Animal: Arm bands
- Big Eater: A common trait on this show but Agumon is the biggest eater of them all.
- Bishōnen Line: ShineGreymon, though in an odd example of this trope, it's also by far his largest form. A better example would be Agumon's pseudo-Burst Mode during the final battle with Yggdrasil.
- Breath Weapon: Pepper breath, Spitfire blast, Mega flame, Mega Burst
- Chest Blaster: One of RizeGreymon's weapons.
- 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".
- Everything's Better with Dinosaurs
- Expy: Of the original Agumon and its digivolution line.
- 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.
- Knightly Sword and Shield: While in Burst Mode, Shine Greymon utilizes the ability to wield a sword and a shield that are both made of fire.
- Light 'em Up: ShineGreymon's Glorious Burst creates a bright ball of flame.
- Only Sane Man: Not quite sane, being incredibly hot-blooded, but has moments in the dub where he tries to talk Marcus out of his Hot-Blooded antics, mainly because of the risk to him. He also tried to calm down Marcus during the physical examinations held in the beginning of episode 19.
- Power Gives You Wings: ShineGreymon already had wings, but going into burst mode turns them into wings of fire. Agumon's pseudo-Burst Mode in the final battle also has a Battle Aura with wings.

- "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.
His digivolutions are as follows:
- In-Training: Wanyamon, a fluffy, blue mon with a cat face and a W on his forehead.
- Rookie: Gaomon, his default form.
- Champion: Gaogamon. Essentially Gaomon on four legs, with a scarf, and more wolf-like.
- Ultimate: MachGaogamon. Gaogamon, with added mecha-armor, and wrestling gear.
- Mega: MirageGaogamon. A knight-like wolf-themed warrior with a big red cape.
- Burst Mode: MirageGaogamon gains jet thrusters and a giant sickle / flail made of light.
- Battle Butler: He is not only Toma's partner on the battlefield, he is also Toma's butler in his manor, often seen serving him tea. Hell, his Catch Phrase is "Yes, Master". You'd be lying if you said that doesn't remind you of Sebastian's "Yes, My Lord".
- Catch Phrase: "Yes, Master." in Japan, "Sir, yes Sir!" in the English dub.
- Chest Blaster: MirageGaogamon's Full Moon Blaster
- Doppelgänger Attack: But they are only mirages, the often looks like a flash step but MirageGaogamon is not as fast as most of the other flash steppers on the show.
- Expy: To Gabumon and its digivolution line.
- Gratuitous English: "Yes, Master!"/"Sir, yes Sir!"
- Lunacy: MirageGaogamon Burst Mode gains its power from the moon.

- Arm Cannon: Marvel Shot and Lila shower are organic versions
- Blade Below the Shoulder: Lilamon can make one.
- Bullet Seed: Seed blast, although technically they are nuts.
- 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.
- 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.
- An 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 bits".
- Faux Action Girl: Subverted, she 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.
- Gratuitous French: Rosemon Burst Mode's attacks are in French in the Japanese version. For example, her main attack was "Aguichant Levres" (Seductive Lips), which was changed into "Kiss of Breath" in the English version.
- Helicopter Blender: But Lalamon is only a rookie so it is not too dangerous.
- Kiss of Death: Burst Mode's "Kiss of Breath".
- Lady of War: Rosemon only. She's usually pretty silly, otherwise.
- Ms. Fanservice: As Rosemon, not only her transformation shows her naked, but also her attack Forbidden Temptation and her breasts have a tendency to "jump" when she fights.

Keenan's partner who was raised alongside him by Frigimon. After Frigimon's death, he follows Keenan to serve Merukimon.
His digivolutions are as follows:
- Rookie: Falcomon, his default form.
- Champion: Peckmon, a yellow, ninja-gear clad ostrich.
- Ultimate: Crowmon (Yatagaramon), a black and purple crow with golden armor and three legs.
- Mega: Ravemon, a samurai with silver bird armor, one white wing, and one black wing.
- Burst Mode: Ravemon's arms and wings merge and turn glowy purple. His armor turns white.
- Badass Adorable: Particularly in the Japanese version, where his voice is much cuter.
- Call a Smeerp a "Rabbit": Can't the designers tell an owl from a falcon? In his defense, Falcomon's original design◊ looked a lot more like a falcon than his current one.◊
- Curb-Stomp Battle: Everytime Falcomon reaches a new evolutionary level, he will always curb-stomp his enemies.
- Peckmon overwhelmed GeoGreymon, Gaogamon, and Sunflowmon and managed to escape before they could fight back.
- Yatagaramon managed to destroy a Gizumon XT, which shrugged off attacks from the other three Perfects and Merukimon.
- Ravemon was able to deal a significant amount of damage to Belphemon Rage Mode to the point that the latter had to unchain himself to recover.
- HeelFace Turn: He turns in earlier than Keenan, due to his temporary allegiance with Marcus and Thomas to obtain the serum needed to cure Yoshi and Keenan from their disease.
- 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.
- Right Hand of Doom: Inversion, Ravemon's small wing is the more dangerous one. The size is reversed this way on purpose to throw off anyone who he may have to fight.

Two PawnChessmons who serve as Miki and Megumi's partners. Like them, they also serve as the computer operators in DATS.

- Ultimate (White): BishopChessmon. A white mechanical bishop.

Sampson's partner who is often seen hanging around his neck. Despite his small stature, he is stronger than he might seem.
His digivolutions are as follows:
- Rookie: Kudamon, his default form.
- Champion: Reppamon, a large white fox with a sickle for a tail.
- Ultimate: Qilinmon, a green Chinese unicorn with big white wings.
- Mega: Kentaurosmon (Sleipmon), a giant eight-legged Equitar with red armor and a big crossbow. One of the Royal Knights.
- Becoming the Mask: He was a member of the Royal Knights and was sent by King Drasil to spy on humans, but became fond of them and changed sides.
- Head Pet: Well, Neck Pet. He enjoys hanging from Sampson's neck.
- Kirin: At the ultimate level he becomes Qilinmon, a Digimon which, as its name implies, is derived from a qilin. It looks like a cross between a dragon and a horse all decked out in armor, and is also classified a Holy Beast Digimon.
- Took a Level in Badass: His Mega form is a freaking Royal Knight!

His digivolutions are as follows:
- Rookie: Kamemon, his default form.
- Champion: Gawappamon, a green plush turtle that fires CDs from it's head.
- Ultimate: Shawjamon, a white clad amphibious Digimon wielding a mystical staff.
- The Quiet One: While he can talk, most of the time he's too shy to do so, as he doesn't like the attention.
- 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.

A wandering Digimon who saved Marcus' group when they were chased off by herds of Gizumon XT. He seems to be knowledgeable about the nature of Digisoul and the Digivices.
- Badass Longcoat: Fanon would have you believe that's he's stolen Jotaro's.
- Blood Less Carnage: When BanchoLeomon "executed" Masaru's father (he didn't really kill him, he "only" wounded him mortally with an energy attack from his fist and then used Suguru's digivice to transfer his sould into his body so that Yggdrasil would be fooled into thinking that Suguru is dead while he could watch and support Masaru from the shadows, but the deception didn't work and Yggdrasil took Suguru's body hostage and used it as an avatar), there was no blood even though he was shot through and the wound rather big.
- Foreshadowing: An early clue that he's sharing a body with Suguru, or at least has a close bond with him, is that his Digisoul is the exact same color as Masaru and Suguru's.
- Luke, I Am Your Father: Shares a body with Marcus' Disappeared Dad
- Mega Neko: He's a giant anthropomorphic lion.
- Running Gag: He's an evolution of Leomon. You know how this goes.
- Shout-Out: Wears the same uniform-with-chain as fellow delinquent and badass Jotaro Kujo
- Big Brother Instinct: After Tsukasa turns evil, he tries his best as his replacement for Yuma.

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.
- Motherly Side Plait: One of the few survivors of this trope.
- 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...
- Stacy's Mom: So much that Thomas gets a crush on her. Marcus wasn't impressed.
- Supreme Chef: Everyone often gushes at how delicious her cookings are.
- Team Mom: Very friendly to the entire DATS team, and even hosts a dinner for them!

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.
- Badass Adorable: She's got enough upper body strength to toss both Keenan and Falcomon in the bathtub.
- Gamer Chick: Surprisingly skilled too, if Thomas' seventeen losses are any indication.
- Girlish Pigtails: That she kept all the way to her middle school years as shown in the Time Skip.
- "I Know You Are in There Somewhere" Fight: Fails one of these with Aquilamon & Garudamon.
- Little Miss Badass: Par for the course with preteen Tamers. In episode 44, she turns Super Saiyan, which is kind of a first for this franchise, though.
- Nightmare Fetishist: A mild case; during a trip to an amusement park, she was outright overjoyed at a sight that had Sarah unnerved and Thomas outright horrified. What sight? The face was never shown but it appeared to be a fairly standard Stringy-Haired Ghost Girl.

- Badass Adorable: Subverted; guess how the Merukimon-VS-Biyomon fight unfolds.
- Brainwashed and Crazy: Though, his non-brainwashed state isn't exactly clever either.
- Honor Before Reason: A big part of his character and the cause of his initial death.
- Playing with Fire: As Garudamon.
- Ridiculously Cute Critter: As Puwamon, his baby form, which can best be described as a little ball of feathers with big Puppy-Dog Eyes.
- Too Dumb to Live: Deconstructed; he fights Merukimon and gets himself killed.

Thomas' sickly half-sister who is brought to Japan to undergo an emergency medication.
- Cuteness Proximity: How she reacts on Gaomon during their first meeting.
- Fusion Dance: Kurata offered to cure her by infusing her with a Digimon, which would essentially turn her into another Bio-Hybrid. Luckily, Thomas managed to stop it for ever happening.
- I Have Your Daughter: Is a victim of this during the late stretch of Kurata arc, because her father made a Deal with the Devil with the mad scientist.
- Intergenerational Friendship: Later on, she develops one with Yushima.
- Missing Mom: Who was later revealed to suffer Death by Childbirth.
- Strapped to a Bomb: The chocker that she's wearing when she was first introduced is revealed to be a bomb made by Kurata. However, Touma was able to remove and destroy it before her surgery started.

One of the Olympus XII and ruler of the Infinite Ice Ridge. He has acted as a father figure for Keenan.
- Anti-Villain: Type III. Near the end of his arc, he tends towards Type IV and arguably Anti-Hero status.
- Attack of the 50-Foot Whatever: He's an outright giant.
- Badass Boast: Claims to be the fastest Digimon ever.
- Dark Is Not Evil: He is a Virus type Digimon and an antagonist when first introduced. He later does a HeelFace Turn, but even then he was a Well-Intentioned Extremist to begin with whose top concern was protecting fellow Digimon from Kurata's genocidal campaign.
- Famous Last Words: "Keenan, be strong."
- Killed Off for Real: He is the first victim on screen to be taken down by one of Kurata's Gizumon XT.
- Knight of Cerebus: Non villainous example, his arrival marked the end of the filler episodes and introduced story arcs. But then again, when he first appears to the DATS, he delivers a Curb-Stomp Battle to them before Biyomon's Heroic Sacrifice against him. That was something.
- Lightning Bruiser: Despite his giant size, he is capable of moving at incredible speeds, particularly his fists.
- Olympus Mons: He is named for the Roman god Mercury (though is not too much like him otherwise) and also incorporates some elements of Aztec Mythology.
- Orcus on His Throne: Not by choice but out of necessity.
- Parental Substitute: He served as Keenan's Father following the death of Frigimon who in turn served as the boy's mother for his biological parents.
- Pragmatic Adaptation: There is already a Mercurymon in Digimon Frontier (Mercuremon in the Japanese version), so Merukimon it was.
- Red Herring: Is initially set up as the Big Bad. As the show goes on it turns out he had nothing to do the early threats facing the human world and his subordinates and allies prove the real danger for his arc.

A messenger of Merukimon who harbors a deep hatred towards Keenan.
His digivolutions are as follows:
- Rookie: Gotsumon, his default form.
- Ultimate: Meteormon (Insekimon), Gotsumon turns white and gains enormous boost of power and speed.
- Co-Dragons: With Keenan and Falcomon until their eventual defection.
- Consummate Liar: He managed to lie to Keenan about how the whole Digital World reject him, and to Merukimon about how Keenan decides to turn against him.
- Enigmatic Minion: Though loyal to Merukimon, he is willing to disobey him to carry out his vendetta against Humans.
- HeelFace Turn: After being reborn.
- Humans Are the Real Monsters: Of the Digimon antagonists in Savers, Gotsumon holds the most contempt for Humans.
- Let's Get Dangerous!: Appears pretty harmless on his for most of his appearances, then he reveals he digivolve into his Ultimate form at will.
- Expy: Of Calumon in that she acts as a catalyst in helping Shinegreymon achieve Burst Mode in a matter relatively similiar to that of Calumon's role in Tamers.
- Mercury's Wings: She has butterfly like wings hidden under her beret.
- Punny Name: Her name, along with Argomon's, is a pun on the word "algorithm".

A sadistic yet 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.
- Absent-Minded Professor: A bit of one when first introduced, particularly when he's around digimon, since he has "allergies" towards them. Of course, this demeanor is a ruse.
- An Offer You Can't Refuse: With Thomas, once his father decides to start working with him.
- Ax-Crazy: He relishes in violence and torture, be they Digimon or humans, and is not above murder or betrayal to further his goals.
- Big Bad: No, he's not the final opponent... but pretty much everything that goes wrong in the series is his fault, so...
- Brains Evil, Brawn Good: Pretty much summarizes his conflict with Digimon. A rare case among Digimon villains, which usually comes down to Brawn vs. Brawn.
- Catch Phrase: "It's SHOWTIME!"
- Despotism Justifies the Means: His ultimate plan.
- 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.
- Disk-One Final Boss: After he's dealt with, the heroes then have to deal with the justifiably infuriated digital God his actions convinced to Kill All Humans.
- Disney Villain Death: After opening the rift between the human world and digital world, he disappears in a flash of light.
- Evil Counterpart: To Spencer Damon. Both are humans that use science as their greatest assets, but whereas Spencer uses his genius to benefit Digimon and mankind alike, Kurata uses his genius to destroy and conquer them. In addition, Spencer will gladly face adversity and when push comes to shove, will even give himself up to let his friends and comrades escape. By contrast, Kurata flees at the slightest sign of danger and always puts himself above any others.
- Expy: Kurata may have one or two roots in the original Big Bad of Digimon World, Analogman.
- Famous Last Words: Very fittingly: "Not this! Please, no! This isn't what I was trying to do!! Argh! NOOOO! Help me... PLEASE!!"
- Fantastic Racism: Against Digimon.
- Faux Affably Evil: His humorous quirks only emphasize how he is easily the most monstrous villain of any Digimon canon.
- Final Solution: Towards Digimon, which single-handedly makes this one of the darkest Digimon series to date.
- Four Eyes, Zero Soul: He wears glasses and is completely unfeeling to anyone around him.
- Freudian Excuse: Subverted in his backstory. Though admittedly Digimon did attack him first, it quickly becomes apparent that he is slaughtering them out of a petty grudge instead of anything else.
- Hate Sink: A sociopath and coward with an irrational hatred of an entire species and insufferably smug demeanor? Yeah, it's pretty easy to hate this guy's guts.
- The Heavy: He has a hand in almost everything that happens in the series. The Digimon who appeared in a Monster of the Week fashion appeared because his various experiments weakened the barrier between worlds, which also allowed Ikuto to be trapped in the Digital World. Even after his death, his actions still set the final arc in motion.
- Humans Are Bastards: Well, he most certainly is, and because of it, the Digimon believe this about ALL humans.
- 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; Koichi the same, only by Cherubimon; Yamaki was a Well-Intentioned Extremist who later pulled off a HeelFace Turn; and Neo Saiba and Ewan/Yuu Amano were manipulated by Daemon and DarkKnightmon, respectively.
- Humans Are Warriors: An evil example. Despite being in a universe filled with warrior monsters, he managers to cause enormous death and destruction through his scientific exploits alone.
- 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 human 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! Further, 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.
- It's All About Me: Literally his MO. His real plan is to conquer both worlds for himself.
- It's Personal: "So, the Data Squad is caught up in a battle. Pity. I'll have to end it." Cue his transportation of all invading Digimon back to the Digital World.
- Kurata: YOU CAN'T WIN! I'M THE BEST!
- 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. The point is ultimately defied when he is using one of those powerful evil Digimon's body to take over the world.
- Karmic Death: And how! Although unfortunately, his action that accidentally caused his own death also had some terrible unforeseen consequences as well. Still doesn't change the fact he got exactly what he deserved though.
- Knight of Cerebus: Despite his comical traits, the entire series gets much darker once he appears thanks to his mass slaughter of Digimon.
- Non-Action Big Bad: Until he fuses with Belphemon.
- Not-So-Well-Intentioned Extremist: His supposed reasoning of Digimon being threats are nothing more than being motivated by irrational fear. Whatever point he had are nullified by using Belphemon's body to try and take over the human world.
- 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 initially wishes to kill all Digimon, 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 World scheme.
- One-Winged Angel: Merges with Belphemon to become Belphemon Rage Mode, his face appearing in its chest.
- Person of Mass Destruction: After merging with Belphemon.
- Self-Disposing Villain: In the end.
- Smug Snake: Most notably shown when he mocks Suguru even when the man stayed behind to allow the rest of the team to escape.
- Take Over the World: Eventually revealed to be his secondary goal (his primary goal still being the genocide of Digimon)
- The Sociopath: Any and all life around him, human or Digimon, are just stepping stones to him.
- This Cannot Be!: His reaction to the DATS not only having regained their memories of their Digimon partners, but actually managing to damage a Gizumon he deployed after them.
- He reacts like this again when Ravemon successfully damages Belphemon.
- Undignified Death: Right before he's presumably vaporized by an explosion he caused in a failed attempt to destroy the Digital World, he's begging for the people he tried to kill to save him.
- Ungrateful Bastard: Towards Spencer Damon.
- Villainous Breakdown: "DAIMON! DAIMON! DAIMON! DAAAAIMOOOOON!"
- Villainous Legacy: Even after Kurata is defeated, his genocide of Digimon makes King Drasil believe all humans are evil, and thus he attempts to destroy the human world to protect the digimon world.
- Wrong Genre Savvy: His actions are foolishly misguided in regards to his own universe-slash-series (and motivated purely by his lust for power), but in light of the Digimon multiverse as a whole (which is a borderline Cosmic Horror Story), his actions are more understandable.
- Xanatos Speed Chess: Very good at this. He frequently sees his plans not as he had intended, but it doesn't phase him. Unless his own life is in danger.

- Always Someone Better: As far strategies go, she's definitely this to Thomas. He can only beat her by overpowering her.
- Dual Wielding: As BioRotosmon she wields a Caduceus in her left hand, and a Rainbow Gem Tipped Staff in her right hand.
- Elegant Gothic Lolita: She commonly appears wearing a black colored version and carrying around a parasoul.
- Evil Genius: When she was younger, she ostracized for her intellect, and chose to work with Kurata thinking she could be with others just as smart as her.
- Fragile Speedster: Compared to Gaomon. In her last fight she's ultimately taken down with a single hit from Mirage Gargomon.
- Foe Romance Subtext: If you've seen the scene, it's pretty self-explanatory. She flat out has a crush on him.

- Japanese Ranguage: Rotus should be Lotus but this and other "translations" were left on the insistence of TOEI Animation employees themselves.
- Quirky Miniboss Squad: With Ivan and Kouki.
- 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...who oddly enough is also a Teen Genius.
- 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, since she was a step ahead of him the entire fight. He only managed to win by abandoning strategy for a plan he had no idea would work or not, an idea he picked up from Marcus. As she herself points out, she lost to Marcus' strength, not Thomas'.
- Villainous Crush: She has one on Thomas.

- 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. Then again, it might simply be that he's less-than-fluent in japanese/english/whatever they speak in-universe.
- Calling Your Attacks: He has a lot of stupid attack names he tries to impress Yoshi with.
- The Brute: If only for his size.
- Dumb Muscle: He plays this role in the trio.

- For the Evulz: Seems to be the only reason he works for Kurata. He's the only one of his trio who does not undergo a HeelFace Turn in the end, and is still misbehaving 5 years into the future.
- Generic Doomsday Villain: While Ivan and Nanami has their motives, he's only motivated by wanting to cause destruction and fighting.
- Hero Insurance: Exploits DATS lack of it.

Originally one of a group of seven powerful Digimon that once terrorized the Digital World, Belphemon was a rather cute-looking Digimon (at least initially) which was weaponized by Kurata, who eventually merged with him after his other means of controlling Belphemon were sabotaged. Belphemon briefly regains control of his body during Kurata's climactic fight with the Data Squad before Kurata took control back.
- Attack of the 50-Foot Whatever: His Rage Mode even makes DATS Digimon's Mega forms look tiny.
- The Berserker: When not under Kurata's control.
- Breath Weapon: At Belphemon's power level, it's practically a small Wave-Motion Gun.
- Combat Tentacles: Belphemon's chains serve this purpose.
- Evil Sounds Deep: Again, when not under Kurata's control.
- Generic Doomsday Villain: He's only briefly acting when not controlled by Kurata, and during that time he simply appears to motivated by causing destruction.
- Make Me Wanna Shout: He can do this in sleep mode.
- Nigh-Invulnerable: His Rage Mode at full strength is impervious anything short of something at least of the level of DATS digimon in Burst Mode.
- Our Dragons Are Different: Rage Mode looks like a demonic dragon.
- Person of Mass Destruction: Even his Sleep Mode is huge jump in power above anything seen before him, flattening a big chunk of the city.
- Sleep-Mode Size: Sleep Mode, which is still quite dangerous, and unlike most examples, is actually enormous, it's only small compared to his Rage Mode.

- "Before the two worlds slash into each other, we must totally eliminate the Human World, first."—King Drasil, through Spencer Daimon
The god of the Digital World. He's not impressed with how humans have been wrecking his world lately.
- Anti-Villain: The guy is only trying to protect the Digimon and Kurata tried to commit genocide against 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 responsible 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."
- Final Boss: The last major enemy the heroes have to deal with in the series.
- God Is Evil: Subverted. He's normally a pretty good guy, it's just a human tried to destroy his subjects, convincing him that Humans Are the Real Monsters.
- Humans Are the Real Monsters: Thanks to Kurata's completely unprovoked attempted genocide of the Digimon, he's come to believe this. Marcus manages to convince him otherwise in the end.
- Jerkass Has a Point: Say what you want, but human history has rarely been idyllic.
- Master Computer: Is revealed to be the computer that oversees the Digital World. His realizing the limitations this comes with is a major plot point.
- One-Winged Angel: After being defeated in Spencer Damon's body, he transforms into a massive machine form.

A group of Digimon, founded by Imperialdramon Paladin Mode, who serve King Drasil in protecting and maintaining order in the Digital world. Its fellowship includes Omnimon, Magnamon, Gallantmon, Dynasmon, LoadKnightmon, UlforceVeedramon, Craniamon, and Leopardmon.
- Attack of the 50-Foot Whatever: Previous seasons had known Digimon be at least one or two heads taller than a normal human adult, but here they are simply gigantic, as big as the protagonist Digimon in their Mega forms.
- Curb-Stomp Battle: Gallantmon hands out two of these to DATS, even against ShineGreymon Burst Mode.
- Deadpan Snarker: Craniamon shows shades in his fight from Marcus and ShineGreymon, responding to his determinator spiel with a weary quip.
- HeelFace Turn: Kudamon/Kentaurosmon is the first to defect, Craniamon is the second, and later all surviving members defect from King Drasil in the last episode.
- Knight Templar: Leopardmon qualifies for his philosophy of "Power Equals Justice".
- Load-Bearing Hero: Craniamon, after he stands in for BanchoLeomon in keeping the worlds from colliding.
- 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.
- Punch-Clock Villain: Gallantmon. He acknowledges Humans Are Flawed, with not all of them being evil, but sees that the destruction of the human world is the only way for the Digital World to survive.
- The Unfought: Dynasmon, Magnamon, UlforceVeedramon, and Omnimon were never directly fought by DATS.

- Animal Motifs: Peacocks, to suit his namesake.
- Big Bad: of Ultimate Power! Burst Mode Activate
- Dumb Muscle: As Argomon Mega, his vocalizations consists of loud screaming and yelling as he wails on ShineGreymon with an unchanging expression, a far cry from his intelligent Ultimate self, but in trade, he is immensely powerful.
- Eyes Do Not Belong There: Argomon has multiple eyes all over its body which are all open except for those on his head. They become open when at Mega level (which is also named Argomon)
- Eye Take: Argomon Mega does this frequently, to unnerving effect.
- Filler Villain: As the movie he stars in is non-canon, he serves as one.
- Foreshadowing: See Punny Name.
- Green Aesop: His motivation, which humans are to blame for.
- Green Thumb: As a plant based Digimon, this is to be expected.
- Humanoid Abomination: Argomon Mega is among the odder looking Megas. Most of it is a massive, black humanoid with an almost action-figure look and with vines and eye markings in some areas.. up until you get to it's chest, which is a gaping cavity of a "second mouth", opening almost like the collar of a jacket that leads to a void of nothing except for numerous, massive eyes. Atop it's long, vine-covered neck is an almost reptilian head with a permanently slackjawed, toothless mouth and unblinking, bulging yellow eyes. It's also extraordinarily powerful to match.
- Humans Are the Real Monsters: Has this opinion, but it is downplayed in comparison to Merukimon and Drasil.
- Impaled with Extreme Prejudice: ShineGreymon executes him this way.
- Kill It with Fire: He fights it off, though. Not until he's impaled by a flaming sword, anyways.
- One-Winged Angel: Argomon Mega, though that seems to compromise all of his intelligible thought.
- Punny Name: He is named after Argus Panoptes.
- Additionally, what do Argomon (or rather, Algomon in the original version) and Rhythm make? Algorithm!
- Suspiciously Similar Substitute: Visually, Argomon Mega can be summed up as a bulky, botanical version of Diaboromon. Justified, as Argomon Ultimate and Infermon can both Digivolve from Chrysalimon. Also, much like Diaboromon, He's impaled by a Digivolution of Agumon.
- Thousand-Yard Stare: Argomon Mega's only expression.
- Wrecked Weapon: To show off just how powerful Argomon Mega is, it manages to shatter ShineGreymon's GeoGrey Sword.
