Izzy izumi

**Koushiro "Izzy" Izumi** (泉 光子郎 *Izumi Kōshirō*?) is a character in the anime and manga series *Digimon Adventure* and *Digimon Adventure 02*. He is a DigiDestined, partnered with Tentomon, and the bearer of the Crest of Knowledge. He is good friends with the popples.

History:

Izzy's real father was a genius mathematician. He and his wife died in a car crash when he was a baby. He was then adopted by Masami Izumi, a distant relative of Izzy's father, and his wife Kae. One night, when Izzy couldn't sleep, he overheard his parents talking about him being adopted. After this shocking discovery, he began to subconsciously distant himself from his parents and focusing on his computer.

In 1995, Izzy's family lived in Highton View Terrace. One night, he witnessed the battle between Red Greymon and Parrotmon. Digimon Adventure This event caused him to be chosen to be a new DigiDestined. The destruction created by the battle caused it to be labeled a terrorist attack, and the Izumi's moved away from the area.

Izzy brought his entire computer setup to summer camp, and is annoyed when none of it works due to the sudden snowstorm. To his chagrin, his technology won't work in the Digital World either. Once in the Digital World, Izzy is very curious about the nature of the Digital World and the Digimon, and tries to come up with theories to explain it all.

When the DigiDestined enter a factory, Izzy finds a large battery and enters. He wipes away a part of the hieroglyphics on the inner wall, causing the factory to stop production. He becomes the first to realize that everything, even the program, is living in the Digital World. He is also delighted to find out his computer works in this factory, and gets distracted trying to make sense of things. He even finds a code that activates his Digivice, though it burns Tentomon out. Izzy's skills with the computer soon prove to be extraordinarily useful for the group when, during the battle against Andromon, Tentomon suggests that Izzy reenter the code that activated his Digivice. When Izzy types it in, Tentomon digivolves into Kabuterimon and destroys the Black Gear affecting Andromon.

When Devimon separates the DigiDestined, Izzy and Tentomon end up in the Ancient Dino Region. They find a temple, and Izzy recognizes the symbols on the ruins as being identical to those in the factory battery. He begins studying them, and is so preoccupied with his computer and his research that he barely notices when Mimi and Palmon arrive. Mimi is insulted by his indifference and runs away crying, with Tentomon in hot pursuit. When they both run into a maze, Izzy pulls out the map and locates Mimi's, directing them out of the maze and saving them when Centarumon attacks.

After he receives a message from Datamon, Izzy uses it to deduce that the Digital World is an alternate world that runs parallel to the Real World. He theorizes that the children may have left their bodies behind when they arrived in the Digital World (a theory that turns out to be false), but later warns Sora that dying in the Digital World would still be very real. After Datamon captures Sora, he figures that Datamon is still inside the pyramid, and helps Tai rescue her.

After Tai and MetalGreymon disappear following the battle against Etemon, Izzy and Tentomon break from the other DigiDestined in hopes of finding Gennai and getting some answers. They run into Vademon, who tricks Izzy into giving up his curiosity and regresses him to an accepting mind that does not question anything. During this state, he sends a message to Tai, telling him not to return to the Digital World. Tentomon frantically tries to get Izzy back to no avail; he slowly reverse digivolves back into Motimon and Pabumon before Izzy snaps out of it. Izzy gets his tag and crest and his curiosity back. In the ensuring battle, the Crest of Knowledge activates, and Kabuterimon Digivolves into MegaKabuterimon and defeats Vademon. Following Izzy's fight with Vademon, Gennai loads his computer with the Digimon Analyzer. This program becomes invaluable when Izzy has to figure out the puzzle to Myotismon's special gate to the Real World.

Once the DigiDestined are back in the Real World, Gennai loads a couple of useful (and some not so useful) programs into Izzy's laptop. One program tracks the movement of Digimon; Izzy sees Raremon attacking Tokyo Bay and rushes out there with Tentomon to stop him. Another program puts up a digital barrier, which stops the Bakemon from taking Izzy and his parents away. Gennai also tells Izzy that the source of Myotismon's power is in the Fuji TV station and describes a prophecy to him. The prophecy aids them in defeating VenomMyotismon; when Izzy reads the prophecy out loud, the group follows its lines. Angemon and Angewomon hit Matt and Tai with arrows of hope and light, which leads to Agumon and Gabumon warp digivolving into their Mega forms, which is of tremendous aid in the battle.

In the lull between battles, Izzy's parents reveal to him that he was adopted, and tell him of his birth parents. Izzy apologize to them for being so distant, and they tell him they're happy to have him as their son.

Izzy's Digimon Analyzer becomes a more valued asset as the DigiDestined battle the Dark Masters. With a loaded a database of Digimon profiles, Izzy can name and describes the characteristics of new Digimon they encounter. However, is proves to be a hindrance against Machinedramon, as Izzy's usage of the computer allows him to track their movements around his city.

After Apocalymon is defeated, Izzy calculates that, because one day in the Digital World equals just one minute in the Real World, the DigiDestined could stay in the Digital World for 118 years. However, Gennai tells them that the time distortion was fixed with the defeat of Apocalymon, and that the solar eclipse would seal the barrier for an indefinite amount of time. Izzy says goodbye to Tentomon, thanking him for being a good friend.

On March 4, 2000, Izzy discovers a Digi-egg infected with a computer virus on the internet, and rushes off to alert the others. He comes over to Tai's house to watch the battle unfold. He is deluged with the number of e-mails coming in, and frantically begs their audience to stop sending them, as their lag is slowing WarGreymon and MetalGarurumon down. After WarGreymon and MetalGarurumon DNA Digivolve into Omnimon and take out all of Diaboromon's clones, however, the remaining Diaboromon is too quick for Omnimon, always jumping away just as Omnimon spots it. Izzy comes up with a plan, forwarding all of the support emails to Diaboromon to slow him down. Omnimon manages to destroy Diaboromon just seconds before the nuclear missiles it launched would have detonated in Japan.

On May 2000, Izzy arrives in the Digital World and gives up his Crest power to free the Digimon Sovereigns. As a result, Tentomon loses the power to become MegaKabuterimon.

Sometime before April 2001, Izzy leaves the soccer club and joins the computers club instead. He quickly becomes a respected member, and is appointed president of the club. He becomes acquainted with Yolei Inoue, another member of the computer club, who looks up to him. During all this time, Izzy keeps in touch with Gennai, sending him emails frequently. As the new DigiDestined gather to battle the Digimon Emperor, Izzy mentors them and continues to play his technical role. He monitors the Digital World and alerts the new DigiDestined to upcoming troubles and problems. Izzy researches the new Digivices and figures they have three new functions, dubbing them the D-3s. In summer, Izzy is kidnapped into another dimension and regresses in age thanks to Wendigomon. The new DigiDestined reverse this. After school is out for the summer, Izzy theorizes that the power of the D-3 is what really opens the gate to the Digital World. This theory proves to be correct, and gives the DigiDestined the ability to open up ports at any time and any location, rather than being limited to simply using the school's computer lab to move in and out of the Digital World. After Izzy and Cody find the Digimon Emperor's base, the new DigiDestined decide to go to the Digital World and stay there until they defeat the Digimon Emperor. Matt and T.K. convince their father to chaperon a camping trip for Izzy, Matt and Tai as a cover up for the younger kids. Izzy later devises the plan to invade the Emperor's base; with Cody's information that a pipeline will cross paths with Ken's base, he directs Agumon and Gabumon to create a diversion. Sometime later, while Izzy monitors the Emperor's downed base, he discovers that it is about to explode. He alerts the new DigiDestined and keeps them updated on its condition while they're trying to stabilize it. Following ExVeemon and Stingmon's Digivolution into Paildramon, Izzy invites the new DigiDestined to his house, and explains how DNA Digivolution works and why the older DigiDestined's Digimon can't Digivolve past Champion anymore. Izzy later takes care of Poromon while Yolei is on a class trip to Kyoto. He visits Ken in his house to discuss Ken's past experiences with the Digital World and the Dark Ocean, and explains to him why the new DigiDestined's Digivices changed their shape and functions. After realizing that Poromon is tired from being in the Real World without his partner for so long, he hands Poromon over to Ken so he can take him to the Digital World to recharge.

On Christmas Day, as Control Spires and wild Digimon appear in the Real World, Izzy gathers all the Japanese DigiDestined in his room and explains the situation. He uses his computer setup to allow Gennai to materialize in the Real World. This allows Gennai to deliver the Harmonious One Azulongmon's power to the DigiDestined, so that their Digimon can once again reach their highest forms. Izzy, Kenna, Omaru, Kari and their Digimon are sent to Hong Kong to help the Asian DigiDestined round up all the loose Digimon and send them back to the Digital World.

Izzy later aids the others in fighting the Daemon Corps and tracking down the children seeded with Dark Spores by Yukio Oikawa. He is present at Highton View Terrace when Oikawa gathers the Dark Spore children and is confronted by the DigiDestined. However, he remains behind when Oikawa, the children and the new DigiDestined enter the world of dreams. When the world is engulfed by MaloMyotismon's darkness, he goes with older DigiDestined and their families to the site of the summer camp from which they were transported to the Digital World years ago. He and the older DigiDestined manage to reach the Digital World from there, and help defeat MaloMyotismon once and for all with the light of their Digivices.
