The hero, a V-Pet owner drawn into the Digimon World after being unable to participate in a V-Pet tournament. Once in the Digimon World, he meets V-dramon, his partner Digimon from that V-Pet.
Action Survivor: He's not afraid to get his hands dirty, but there isn't much he can do against a Digimon that isn't a baby.
Goggles Do Nothing: Initially played straight, but then subverted by Taichi, who uses the goggles when riding on Zero's back in flight like a pilot would. He also discusses their personal meaning for him.
Let's Get Dangerous: Much to the surprise of many of his opponents, and even his allies when they learn just how Badass this goofy human can be.
Magnetic Hero: He inspires many who would have otherwise been too scared to fight Demon's army.
The Medic: Mostly basic cleaning and bandaging but he also knows his salves.
Merchandise Driven: The Digimon of choice of every tamer in this manga was available in the first two waves of Digimon virtual pets. Taichi's V-Pet of choice was the original Digital Monster Ver. 1. The thing is that it didn't act like a normal copy of said pet since his Botamon ended up as a V-dramon.
Taichi's partner Digimon, a V-dramon, often called just "Zero". Born from Taichi's Digital Monster Ver.1 virtual pet, he was an anomalous Digimon who wasn't supposed to exist in the devices (this didn't remain the case for long though) and so caused Taichi to be disqualified from the competition. He met Taichi shortly after he was drawn into the Digimon World, taking physical form there.His evolved forms are as follows*
Note that as Zeromaru evolves, as with almost all Digimon in this manga, he stays in his new form permanently
:
Botamon, Koromon and Agumon, his Baby, Baby II and Child forms; *
only Botamon is shown in the comic but Taichi says Zero used to be like the Agumon training at the castle, so Agumon and Koromon are the most likely forms. The two after Botamon could be anything though since V-dramon couldn't be gotten from the established Botamon paths at that time.
V-dramon, his Adult form and his form at the beginning. A large blue dragon with three horns.
AeroV-dramon, his Perfect form. A larger, more powerful V-Dramon, but his biggest development is growing two great wings.
UlforceV-dramon, his Ultimate form. A holy dragon knight dressed in Blue Digizoid armor, with a Laser Sword equipped to his right gauntlet.
UlforceV-dramon Future Mode, his Super Ultimate form. Drawing on the power of the Digimental, an immensely powerful warrior.
Merchandise and Story Segregation: Everyone points out that V-dramon is a species that doesn't exist in normal virtual pets at the beginning, but at one point Taichi mentions the newly-released Digimon Pendulum virtual pets, the ones presumably used by Hideto, Sigma and Mari. The Pendulum was the virtual pet in which V-dramon and AeroV-dramon legitimately debuted as potential partner Digimon; Mari probably owns the specific version in which the two appeared! Of course, that doesn't mean they suddenly exist in the Digital Monster Ver.1, the Ver.4 Veedramon has to come from a different path than Zero did and there was no Ulforce V-dramon at all, keeping in line with the story.
Genre Blind: At times Zero seems to think he's in a different kind of fighting series. Part of it is retroactive though, since Digimon's tropes were still being cemented during this comic's run.
I Am Not Weasel: It seems like it would be hard to get his species so wrong, but given the way digimon work in this series, he may not look much like dragon to everyone who doesn't see him as one. Eventually he gives up on correcting people.
Mighty Glacier, though a little quicker than some expect
Lightning Bruiser: becomes one of the fast moving bruiser variety, much to the surprise of many of his foes.
A Leomon who serves as the commander of Lord HolyAngemon's army. He is a hard taskmaster, but is wholly devoted to the protection of Holy Angel Castle and is kinder than he would like to let on.His evolved forms are as follows:
Leomon, his Adult and the form he takes initially.
Panjyamon, his Perfect form. A white, ice-themed Palette Swap of Leomon.
Regulumon, his Ultimate form. An enormous muscular lion warrior.
The ruler of the Holy Angel Castle, the force responsible for fending off Demon's assault on the Digimon World, and the one responsible for drawing Taichi into the Digimon World to help out.His evolved forms are as follows:
HolyAngemon, his Perfect form and his default form. There are two variations on this form: he spends most of his time in the white-robedPriest Mode, but can transform into the armoured Battle Mode.
Seraphimon, his first Ultimate form. An immensely powerful ten-winged angel dressed in ornate blue armour.
Dominimon, his second Ultimate form. Accessed after his loss to Arkadimon and the subsequent drop of his Win Ratio, a six-winged blue angel of lesser power than Seraphimon.
A Gomamon living in the Net Ocean, who regularly braves the dangers of the Ocean to keep Lord Whamon informed of the events of the wider world.His evolved forms are as follows:
Ikkakumon, his Adult form and the form he takes as the new guardian of the Net Ocean. A giant furred walrus with a single horn.
The younger sister of Neo Saiba, who was found by Taichi wandering the Digimon World alone and subsequently joined him. She was paralyzed from the waist down some time before entering the Digimon World, and the accident weighs heavily on both Neo and Hideto.
Expy: Sora Takenouchi resembles her, but that's really where the similarities end.
For Your Own Good: She is never told outright but her accident and injury is the primary motivation for everything Neo and Hideto do in serving Demon.
Guilt Complex: It's masked by her sunny disposition, but it's there.
I Can't Feel My Legs: In the Digimon World, her ability to walk is restored temporarily, but otherwise this is her situation.
The Pollyana: How she was viewed by Hideto and kind of was until he and Neo went crazy(see guilt complex)
Voice Of Reason:She thought she acted as this to Neo but didn't get through
Igamon
A ninja Digimon in the service of Lord HolyAngemon, assigned to observe Demon's castle. He departed to warn Taichi of the birth and evolution of Arkadimon, and later joined Taichi's group for the rest of his journey.
Distressed Dude: Captured by Mari and Rosemon while traveling to notify Lord HolyAngemon of the impending assault by Neo.
Failure Hero: During and after the encounter with Mari, he spends quite a while fretting about this.
Flaming Sword: he sticks it in a fire to get the effect, it is not a special ability
The antagonist, a power-hungry Demon Lord Digimon who seeks to conquer the world.His evolved forms are as follows:
Daemon, his Ultimate form and his default form.
Daemon Super Ultimate, his Super Ultimate form, attained by killing and absorbing Arkadimon Super Ultimate from within. A more humanoid take on Daemon, wielding immense power.
Big Bad: The opposing force to Lords Whamon and HolyAngemon
Dystopia Justifies The Means: He truly believes the Digimon World will be better off under him, regardless of how miserable it would make anyone who lives in it.
Emotion Control: How he's swayed his more unlikely followers
Evil Counterpart: In the broader Digimon canon, Daemon is treated as a Fallen Angel counterpart to Seraphimon, the evolved form of HolyAngemon. This puts the relationship between Lord Demon and Lord HolyAngemon in quite a new light.
Mutants: He, and several other antagonists are described as such. (Outside of this comic, very few of them actually are, even many mutant monsters created in this series tend to get different labels)
Just for Pun, a meta-example. This incarnation of Daemon is lacking the Black Cloak sported by his multiversal brethren. To make-up for it, he's the only one who gets to kick it up a notch.
Straw Hypocrite: He explains to Etemonkey that monsters fight better when tamed by humans. He actually believed the opposite but needed to convince Neo to work for him.
Maniac Monkeys: Averted, in that he actually likes and admires humans.
Neo Saiba
An arrogant tamer who first encountered Taichi in the V-Pet tournament at the beginning. He too was drawn into the Digimon World, this time by Demon, and serves him as the tamer of the "super ultimate" Digimon, Arkadimon. Before Arkadimon was born, Neo was the tamer of multiple Digimon, discarding those who lost in combat.
Irony: Nicer people just assume Zero is a glitch, but Shinichiro Josaki accuses Taichi of cheating by making a new monster. Not only because Shinichiro did that himself but also because it's Neo's modus operandi.
Kick the Dog: Neo does this constantly, partly to remind us that he's gone off the deep end, morally speaking.
Manipulative Bastard: Or at least he thinks he is. Demon is the real manipulator here.
Used to Be a Sweet Kid: Those who say this are possibly looking back through nostalgia goggles, as he was always something of an ass, but he unarguably got worse.
Well-Intentioned Extremist: The world Neo wants to create wouldn't be so bad to live in and his reasons are respectable enough. His way of getting to that goal is the problem; that, and the fact Lord Demon is the one who's benefiting.
Neo's (current) partner Digimon. The immensely powerful "super ultimate" Digimon which Demon selected Neo to raise. All of Arkadimon's evolved forms are named "Arkadimon", each appended with the level to indicate the difference. It's evolutions will ultimately end with an Eldritch Abomination, or so it is said, Neo has other plans.
The guardian of the Metal Empire Tamer Tag. Formerly a Greymon belonging to Neo, he was discarded and deleted after a lost battle, but pulled himself together, mechanised his body and evolved to MetalGreymon out of sheer determination to survive and prove his true worth to Neo. Neo, for his part, wasn't interested.
Gradual Grinder: Played with: Neo had him simply stand there and take Zeromaru's attacks head-on, even though he was perfectly capable of overwhelming Zeromaru with his offensive capabilities. Neo's motivations for this were actually less than kind - he was using MetalGreymon as a way of having Zeromaru show off the full extent of his offensive capabilities so as to record data on him, and he could not care less about what happens to MetalGreymon.
One of the first artificial Digimon created by Neo, born by merging a Grizzmon with a sample of the power data of Arkadimon. It was dispatched to apprehend Rei during her escape from Demon's castle, but was stopped by the arrival of Taichi and Zero.
Badass Boast: Its constant boasts that it is a "new Digimon for a new age", well beyond the average sort of Digimon previously faced by Taichi and Zero.
Quirky Miniboss Squad: Was supposed to be part of one but the other three were scrapped to meet the deadline. You can still see them in two panels if you look close enough.
Sadly Mythtaken: In universe, Neo named him after a female figure
Scary Teeth:Brown bears usually have a dental structure similar to human's but Callismon's mouth is full of fangs, fangs just like Zero's. Likey an intentional design choice by Neo.
Shockwave Stomp: Or rather he punches the ground. Not a special attack, more like an act of frustration
Wake Up Call Boss: The first non-Alias III Digimon to really put up much of a fight to Zeromaru as AeroV-dramon.
The Alias III
Sigma
The "Alias I", a highly introverted masked boy who communicates solely through a vocalisation program on his computer, feeling this is the only way he can express himself. His partner Digimon is Piemon.
Merchandise Driven: Based on Piemon's existence, Sigma probably originally owned a Pendulum 3.0 Nightmare Soldiers virtual pet.
No One Will Ever Know: Played with. He wants to be himself, but after he learned what his "real" friends were really like, chat rooms were the only place he was comfortable enough to do so, symbolically demonstrated by constantly wearing his mask.
Innocent Fanservice Girl: As part of her Confusion Fu, she seems to attempt to invoke this in-universe by having her top be blown off by Zeromaru's wind attacks.
The "Alias III" of the Alias III, a trio of tamers convened by Neo to serve him. Hideto was a friend of Neo and Rei long before the events of the manga, and never quite got over Rei's accident. His two partner Digimon are Warg and Melga.
Merchandise Driven: Based on Warg and Melga, it can be deduced that Hideto probably originally owned two copies of the Pendulum ZERO Virus Busters virtual pet, as it was the pet at the time which featured WarGreymon, MetalGarurumon and the ability to Jogress them into Omegamon.
Hideto's dual partner Digimon, a WarGreymon and MetalGarurumon respectively. They spend most of their time jogressed together into Omegamon, an immensely powerful holy knight Digimon.
Fusion Dance: Omegamon, obviously. Fusion Dancing and reverting from it forms the backbone of Hideto's combat strategies.
Glowing Eyes of Doom: He can freeze Digimon champion level and below in their tracks with just a gaze
I Let You Win: Omegamon took Zero's Dragon Impulse on purpose and didn't let Hideto jogress Warg and Melga because he realised that Taichi and Zero really were good guys.
