Digimon : The Ultimate Doom

Prologue

Digimon Adventure

On August 1 , 1999 , seven children from Japan are

suddenly thrust into a strange dimension called the

"Digital World" while they are at summer camp.

During their adventure, children Tai , Matt, Sora, Izzy,

Mimi , Joe, and T.K. , discover that they are in a land

where digital creatures called "Digimon" dwell.

Befriending seven other Digimon, the children learn

that they have the ability to help their partners

digitally evolve (digivolve) into stronger, powerful

forms that can combat enemies for a short amount of

time. Setting off on their journey, the children start

searching for a way home.

The children later learn that they are the

"DigiDestined", chosen children with compatibilities

with Digimon, and they are the only hope in

destroying the evil that is slowly consuming the

Digital World. When the culprit reveals himself to be

Devimon, who sent Black Gears that would brainwash

other Digimon into attacking them, he begins

targeting T.K. and Patamon, as the two have the

most effective power against him. Fortunately,

Patamon, as Angemon, defeats him at the cost of his

own life and is reborn as a Digimon Egg. However,

Devimon is only a pawn in a greater threat, forcing

the DigiDestined to move out across the world.

The DigiDestined travel to the continent Server and

learn they have the ability to help their Digimon

digivolve further with the power of Crests. However,

Etemon, who runs his Dark Network across the

continent, is also interested in them and attempts to

prevent the DigiDestined from obtaining them. Once

all the Crests have been gathered, Tai and

MetalGreymon destroy Etemon and his Dark Network

for good. Unfortunately, they slip into the Real World,

where they realize that evil Digimon have begun

crossing a dimensional gate from the Digital World to

enter Earth.

Tai returns to the Digital World to round up the

DigiDestined, where he learns of another threat,

Myotismon, who is preventing them from working

together and activating their Crests. When

Myotismon fails, he decides to enter the Real World to

capture a pre-destined eighth DigiDestined child.

Once the DigiDestined return to their hometown,

shortly after, Tai learns that his younger sister, Kari ,

is the eighth child and is partnered with Gatomon,

one of Myotismon's henchmen. Once Myotismon is

destroyed, the DigiDestined realize that the Digital

World has grown worse since their departure.

Upon returning, the Dark Masters, four elite evil

Digimon, reveal themselves to be the true culprits

behind every enemy the DigiDestined had faced thus

far. As the DigiDestined battle them while losing allies

in the process, they experience hardships of their

own, including their group temporarily disbanding.

However, all of them realize they cannot save the

Digital World without each other, and once the last

Dark Master is defeated, Apocalymon reveals himself

to be their final enemy. Once he is defeated, the

children returned to the Real World, leaving their

Digimon partners behind.

Digimon Adventure 02

Taking place a few years after Digimon Adventure, the

Digital World comes under attack by a mysterious

human calling himself the Digimon Emperor who is

enslaving Digimon with his black rings while building

Control Spires that negate Digivolution. To fight him,

T.K and Kari, along with three new children, gain a

type of Digivice called a D3 , which allows them to

open a gate to be transported to the Digital World

through any computer and a D-Terminal that holds

Crest-themed relics called Digi-Eggs ( DigiMentals)

that allow Patamon and Gatomon, along with the new

Digimon Veemon, Hawkmon, and Armadillomon to

Armor Digivolve as a counter to the presence of

Control Spires. They eventually stop the Digimon

Emperor, revealed to be the boy genius Ken Ichijouji,

thanks to the sacrifice of Wormmon , Ken's partner.

With the Digimon Emperor defeated, the DigiDestined

proceed to help the resident Digimon rebuild their

homes. However, after his defeat, and soul searching,

Ken learns of a mysterious woman who can turn

Control Spires into constructs resembling living

Digimon. Though Veemon, Hawkmon, and

Armadillomon were able to Digivolve naturally, the

Control Spire Digimon prove to be stronger until Ken

joins the gang and they learn of DNA Digivolution,

enabling their Digimon to fuse with each other in pairs

for more power. However, the mysterious woman,

revealed to be a human-Digimon hybrid called

Arukenimon, responds by creating BlackWarGreymon.

Though the construct refuses to follow her orders,

Arukenimon and her lackey Mummymon take

advantage of his drive to destroy the Destiny Stones

that keep the dimensional barriers of the human and

Digital Worlds from blending.

Eventually, when the battle was brought to the Real

World, Arukenimon and Mummymon's boss, Yukio

Oikawa, makes himself known. Despite interference

from Daemon and his forces, Oikawa extracts from

Ken data of the Dark Spore, the object responsible for

Ken becoming the Digimon Emperor, and copies it

into a group of children who wish for the greatness

the old, evil Ken had. Those spores develop into

flowers that harvest the infected children's energy.

Eventually, the DigiDestined confront Oikawa, only to

learn he is a loner whose only friend in the world was

the late Hiroki Hida, Cody's father, and that his

actions were so he can enter the DigiWorld.

However, it was then revealed as Oikawa attempted

to make his way into the Digital World that he was

only a pawn/vessel for the true mastermind,

Myotismon from the first series, now reborn as

MaloMyotismon. Eventually, after a long battle with

aid from the DigiDestined from all over the world, the

Japanese DigiDestined destroyed MaloMyotismon.

Digimon Frontier

Long ago, a group of ten Digimon sacrificed

themselves to defeat an ultimate evil that threatened

the Digital World. These Ancient Warriors created

artifacts from their data, the twenty "Spirits" (ten

Beast spirits and ten Human spirits, one of each for

each element), before leaving the Digital World in the

care of the three Celestial Digimon. However, one of

the three, Cherubimon begins a reign of terror. To

counter this, the Celestial Digimon Ophanimon

summons five children from the human world into the

Digital World via the train-like Trailmon . There, these

five Digi-Destined find their respective Human Spirits

and "Spirit Evolve" into Digimon, the Legendary

Warriors. However, while finding their respective

Beast Spirits, the five find themselves hunted by five

other Legendary Warriors that serve Cherubimon (for

five of these spirits were given to the care of

Cherubimon before his corruption).

After they defeat four of them (JP destroys one,

another loses his Beast Spirit to Koji and is destroyed

by Duskmon for being useless, Zoe destroys another

and Takuya destroys the last one), Koji Minamoto

discovers that Duskmon, the fifth evil Legendary

Warrior, is really his twin brother Koichi Kimura . With

Takuya Kanbara 's help, Koji is able to free his brother,

and Kouichi restores the Spirits of Darkness to their

true forms and joins the team as the true Warrior of

Darkness, Löwemon .

After they defeat Cherubimon, who is killed by Takuya

as EmperorGreymon, the DigiDestined learn that the

true mastermind was the very evil the Ancient

Warriors sealed away within the Digital World's core,

Lucemon. So now the six DigiDestined must try to

defeat the two Royal Knights who were sent by

Lucemon to scan all of the Digital world's data to

complete his rebirth. Ultimately Takuya and Koji

succeed in defeating the Knights, but not before they

destroy and scan the whole digital world and free

Lucemon (who scans the Royal Knights after the

DigiDestined defeat them, allowing him to evolve to a

more powerful form than he was before). At this point,

after defeating Takuya and Koji as EmperorGreymon

and MagnaGarurumon, Lucemon destroys the Digital

World's moons. He then began opening a portal to

the real world: a portal that leads to the underground

train station in which the DigiDestined were brought.

He is confronted by the Digidestined who try to attack

him with a mutli hit tactic, fighting together as a

complete team. However Lucemon ends up killing

Koichi (who sacrificed himself to save the others).

Forming the ultimate Legendary Warrior Digimon

Susanoomon by combining all the spirits in Takuya

and Koji, Lucemon is defeated and scanned.

However, all of his evil transforms into another form of

Lucemon, one of pure evil, which tries to go to the

real world. Having almost given up, the spirits of the

Ten Legendary Warriors come to life, along with the

spirits of Ophanimon, Cherubimon and Seraphimon,

giving the kids new hope. Together, they all form a

seemingly more powerful Susanoomon, and defeat

and ultimately destroy Lucemon (at least the evil part

of Lucemon) once and for all, giving the Digital World

its data back, ultimately restoring its true form. The

children go back to the real world and find that an

hour hasn't even passed since they left (only a 1/2

hour at most). They find Koichi, who they discover

was only in the Digital World for having been in a

coma for falling down a flight of stairs. He then wakes

up when Koji arrives, leading everyone into living

happily ever after, having the events of the Digital

World change them forever.

Digimon Xros Wars season 1

Taiki Kudō, a 7th grade boy, heard a mysterious

melody and followed it to an alley where a

mysterious, legendary Digivice called the Xros Loader

appeared in front of him. Accompanied by his friends,

Akari Hinomoto and Zenjirō Tsurugi, they were

dragged into the Digital World. They soon realized

that the Digital World was a place inhabited by living

creatures named Digimon and is now slowly being

taken over by an evil empire named the Bagra Army.

Now, Taiki and his "Xros Heart" team become an

important figure to free the world from the Bagra

Army, led by their Emperor Bagramon.

When the Digital World was separated into 108 Zones

with an element named "Code Crown" placed in each

Zone, it invites few parties to collect the Code Crown

to claim each Zone, to achieve the goal into uniting

and taking over the Digital World. Feeling the strong

responsibility to save the world, Taiki forms his own

group named Xros Heart, which is considered a

strong threat to the Bagra Army, and battles along

with some other parties including another human boy,

Kiriha Aonuma, and his Blue Flare group. Also a

human girl, Nene Amano, with her team Twilight.

However, Nene is later revealed to be a figurehead for

Twilight's true leader DarkKnightmon, who

blackmailed her into aiding him. But when he

attempts to dispose of her once she outlived her

usefulness, Nene joins Xros Heart. Later on, Xros

Heart learns that the Code Crowns have the power to

make the wishes of those who reunite them come

true, but Bagramon manages to take them all while

Taiki, Akari, and Zenjirō are sent back to the human

world along with Shoutmon and Tactimon. With Xros

Heart's core members disposed of, Bagramon reveals

DarkKnightmon to be his younger brother as they

begin their reign over the Digital World.

Ending up in their hometown of Kyoto, the human

Xros Heart members and Shoutmon meet Omnimon,

a DigiMemory-sealed Digimon who gave Taiki his red

Xros Loader. However, a giant Tactimon appears

causing havoc, but thanks to the courage of Akari

and friendship of Zenjirō, Shoutmon is able to

digivolve to OmegaShoutmon and destroys Tactimon

for good. Then, Omnimon use his remaining energy to

send Taiki and Shoutmon back to the Digital World

while Akari and Zenjirō wait for their chance to return

the Digital World to assist Taiki.

Digimon Xros Wars season 2 : The Evil Death Generals and the Seven Kingdoms

Upon returning to the Digital World, Taiki and

Shoutmon learn that Bagramon had it reconstructed

into a empire surrounding by seven Kingdoms, each

ruled by a denominated Death General with their own

Darkness Loaders gained from their now-Admiral

DarkKnightmon. Reunited with their allies, Taiki and

Nene convince Kiriha to join forces with them and

they set to travel together through the Kingdoms to

defeat the Generals. They also have to face Nene's

brother, Yū Amano, who becomes DarkKnightmon's

human partner and joins the Bagra Army by thinking

the Digital World as a game for his pleasure.

Meanwhile, Bagramon adds negative energy, gained

from his seven Generals, into his Code Crown and

transforms it into the "Dark Stone" for his upcoming

day for ultimate destruction, which he calls "D5".

During the journey, more about the main characters

past is revealed, some Digimon are killed in battle and

a new DigiXros called the Great Xros giving Shoutmon

the power to become Shoutmon X7. After defeating

the Death Generals, and opening Yū's eyes to the

truth, the Xros Heart United Army finally confronts

Bagramon. But in a turn of events, having gathered

the energy needed, Bagramon reveals that D5 is the

"Dimension Delete and Deadly Destruction Day" that

would cast both the real and digital worlds in

darkness which would combine them with Bagramon

himself reigning over a new world.

Though DarkKnightmon reveals his true colors in an

act to absorb his brother by forcibly DigiXrossing with

him, his actions only worsen things when Bagramon's

destroys DarkKnightmon from the inside and

reconfigures his brother's body into

DarknessBagramon. In the process, Shoutmon dies

while Bagramon sends Taiki and his friends to an

empty space, where they are saved by Akari and

Zenjirō using two DigiMemories. In the final battle,

Yū's Darkness Loader turned into a yellow Xros

Loader for his use. Taiki, Akari and Cutemon decide

to go inside the Dark Stone to find Shoutmon where

they are attacked by the metaphysical incarnation of

Bagramon. When the completed Code Crown chooses

Taiki and not Bagramon as its true owner, Shoutmon

revives alongside all dead Digimon (including allies

and enemies) while the DigiMemories regain their

original forms. From there, the Digimon are all

DigiXrossesed Shoutmon X7 Superior Mode who

destroys DarknessBagramon and save both worlds.

All the Digimon returned to the Digital World while

Taiki and his friends resume their lives in the human

world.

Digimon Xros Wars season 3: The Young Hunters Who Leapt Through Time

A year has passed since the battle against Bagramon,

and Team Xros Heart has become a basketball team

consisting of Taiki, Yū and his classmate, Tagiru

Akashi. One day, Tagiru discovers a strange, unstable

realm in-between the human and digital worlds,

known as the Digi Quartz , where Xros Loader wielding children

known as Digimon Hunters hunt down and capture

Digimon that escape from the Digital World and feed

off the negative emotions of humans. Given a Xros

Loader by a strange old man and accompanied by a

Digimon named Gumdramon, Tagiru, along with Taiki,

Yū and their Digimon, join the Digimon Hunt to

investigate and protect their world from rampant

Digimon, while clashing against rival hunters.

In the end, the Clock Store Owner reveals to everyone

the truth: The remaining power from Bagramon after

his defeat and the Digital Power in the human world

created a deadly Digimon called Quartzmon whose

goal is to change the entire human world into

DigiQuartz while eliminating every human. To fight

that, the Clock Store Owner travels to different

timelines, bringing known heroes from other Digital

Worlds to unlock the "Brave Snatcher", created from

Bagramon's right arm, in order to defeat Quartzmon.

While a Hunter named Ryōma was chosen to be the

one to hunt Quartzmon, Ryōma turned out to be

manipulated by Quartzmon, gravely injuring Taiki.

Tagiru is chosen as Taiki and Ryōma's replacement

and, in a decisive battle, uses the power of the Brave

Snatcher to defeat Quartzmon and capture his

DigiEgg. With Quartzmon defeated, the balance

between the Human and Digital Worlds is restored,

forcing the Hunters, their Digimons and the heroes

from other timelines to get separated and return to

their original places.

A month after Quartzmon's defeat, Tagiru and

Gumdramon are reunited and the Clock Store Owner

reappears, revealing that there are still some Digimon

running astray in the Human World. In the occasion,

Taiki confirms his suspicion that the Clock Store

Owner is actually the reincarnation of Bagramon, now

dedicated to protect the Human and Digital Worlds

instead of conquering them.
