Card Game Evolution[edit]



Digimon Adventure[edit]

Gennai appeared first to the Chosen Children as a very old man, but when Yagami Hikari is possessed by the powers of light and gives them a glimpse of the history of the Digital World, he is seen as a young man wearing robes and a hood, apparently one among many of his kind. Gennai and his group were the ones that created the Digivices, Tags, and Crests, as well as the Partner Digimon.

Soon, however, the Dark Masters discovered their plans, and Piemon, along with an army of Guardromon and Mechanorimon, invaded and destroyed the secret base, killing all save Gennai. Piemon stole the Tags and Crests, but Gennai interrupted him by attacking him. Piemon inserted a mysterious black ball in Gennai, and Gennai leapt into a Mechanorimon, taking all of the Digivices and Digitamas aside from Tailmon's, which he lost.

At some point after Digimon Adventure, Gennai called the Chosen Children back into the Digital World to ask them to give up the power of their Crests to add another layer of protection to the Digital World, which they did. He did not appear again until the second series, where he appeared as a young man. It is thought that he accomplished this by copying himself, as many more of his kind later appeared in the series, and one of them stated that he and Gennai were once one and the same. It is possible that the people seen with him in the flashback in the first series were also copies of the original Gennai and he is in fact, a single entity.

Throughout the first and second series, Gennai takes a backstage role to helping the Chosen Children. He calls them to the Server Continent to defeat Etemon, he helps them get through Vamdemon's interdimensional gate, he gives Izumi Koushirou a Digital Barrier program, and he tells them of the existence of Apocalymon, the final enemy.

Digimon Adventure 02[edit]

In the second series, Gennai resurfaces younger than ever and aids them during the World Tour arc and caused the eight original Digimon to regain their ability to Super Evolve to Perfect thanks to one of Qinglongmon's Digicores, which also allows Paildramon to become Imperialdramon: Dragon Mode. He has counterparts in the locations that the Chosen Children were taken to by Imperialdramon. He appears at the end, returning to Tailmon her lost Holy Ring, which he explains was used to enable Jogress Evolving.

Digimon Adventure tri.[edit]

Digimon Adventure: Last Evolution Kizuna[edit]

Gennai (in his younger form) appears to Yagami Taichi after the countdown to Agumon leaving him started. Taichi asks him if there's any way to avoid it, but Gennai tells him it is inevitable and explains to him that it happens because children have the power of countless possibilities, but as they grow, those become limited.

Digimon Adventure[edit]

Gennai appears for the first time in Episode 18, "Angemon's Awakening!", showing himself to the Chosen Children and Leomon after they defeated Devimon. He quickly said he was on their side, and Takenouchi Sora wondered about another human being being in the Digital World, though Gennai explained he was and was not a human, which made Tachikawa Mimi believe he was a ghost. He then introduced himself, explaining that Devimon's interference had made it impossible for him to contact them earlier. Mimi then asked him if he was the one who chose them, though Gennai said he wasn't and he didn't know who was. He then explained he was on the other side of the ocean and the Chosen Children had to defeat an enemy on Server Continent, though Izumi Koshiro pointed out they didn't know where that was or if they could win. However, Gennai could send a map to Koshiro's computer, and told them to search for the Tags and Crests, which they would need to make their Digimon evolve further. After Kido Jo asked Gennai where to find them, he answered that Devimon had sealed the Tags together, but the Crests were scattered around Server Continent. Afterwards, the connection was lost and Gennai disappeared.

Gennai contacts the Chosen Children as a hologram once again in Episode 22, "Cockatrimon, the Illusionary Ship's Captain!". Before letting him talk, Yagami Taichi complained about them getting the Tags and Crests but failing to evolve their Digimon, and Mimi cried she did not want them. However, Gennai asked them to calm down and pointed out they would get their Crests even if they didn't want them as the Tags and Crests were drawn to each other, though even with them, they would have a repeat of the Skull Greymon incident if they didn't properly raise their Digimon. Taichi then asked him what raising their Digimon properly meant, but the connection cut out before he could answer.

Gennai reappeared in front of Koshiro, Mochimon, Ishida Yamato, Tunomon, Takaishi Takeru and Patamon outside of Vademon's Den after the first two defeated Vademon in Episode 28, "Breaking Through! Atlur Kabuterimon". There, he told them the distortions in the Digital World had not been corrected yet and that he believed in them, before disappearing.

After the Chosen Children ran away from Vamdemon in Episode 30, "Shining Wings! Garudamon", Gennai's hologram once again appeared before them bearing both good and bad news. Yamato asked him to give them the good news first as they'd be disappointed either way, said good news were that he had found them a new comrade, as there are eight Chosen Children, to everyone's shock, and all of them are needed to fix the Digital World's distortions and said distortions would affect the Real World as well. Taichi then asked him about their name and whereabouts, he didn't know the former, but he did know that they were in Japan, a place Gabumon didn't know but Agumon did as he had been there already. Gennai then told them the bad news: Vamdemon was aware of all of this and was heading to Japan to reach them first, raising an army to find and kill them. Gennai then told them that a gate to Japan was located in Vamdemon Castle and he was counting on them to stop Vamdemon's plan and save their comrade, before his hologram once again vanished.

Gennai's hologram talked to the Chosen Children once again after they escaped from Vamdemon Castle in Episode 31, "Vamdemon, the Castle of Darkness". He considered the situation a shame. This angered them, as the situation was much worse than that, with the eighth Chosen Child and Japan in danger. Taichi asked Gennai if there was another way to open the gate, which Gennai confirmed but couldn't explain, instead asking them to go to his house, which they could find by following a light. They go to it in Episode 32, "Gennai Tells All", but find nothing other than said light coming out of a lake, which Koshiro realizes is why he couldn't find anything even after searching the mountains for two months. A staircase then appeared in the lake, breaking it and allowing the Chosen Children entrance. Inside, they found the house proper, as well as a garden with a pond and a bridge over it, and on top of the bridge, the real Gennai. Once he confirmed this was the case, Taichi asked him why he never met them in person before, which he answered was because he was a stay-at-home kind of guy and had little free time. Gennai then took the Chosen Children to a room with maps, where he told them where Vamdemon currently was: Hikarigaoka. He then explained how to answer the gate, through the use of cards on the slate in front of the gate, though he warned them that a mistake in placing them could send them to another world or make them fail to come out in one piece.

The next day, Gennai told the Chosen Children that they faced a difficult situation and should believe in their own abilities before they left.

Gennai sent an e-mail to Koshiro in Episode 37, "Raremon! The Surprise Attack on Tokyo Bay", warning him about how an unidentified Digimon, later confirmed to be Raremon, had landed in Shibaura.

At some point before Episode 47, "She Descends! Angewomon!", Gennai told Koshiro that the center of the fog barrier covering Odaiba was on the roof of the Tokyo Big Sight building.

Gennai sent an e-mail to Koshiro in Episode 48, "The Resurrected Venom Vamdemon", telling them to rejoice as he found a hint on how to defeat Vamdemon. He had found a poem with a prophecy in ancient ruins, saying how he'd revive and then a miracle would happen.

As Homeostasis explained in Episode 53, "Clash! The Ultimate Digimon", in the past, a young Gennai protected the Crests and Partner Digimon Digitama from Piemon by taking them to File Island, but due to the interference of his pursuers, lost Tailmon's Digitama.

After the Chosen Children defeated the last Dark Master, Piemon, in Episode 61, "The Clown from Hell, Piemon", Gennai sent Koshiro an e-mail to tell him their true enemy wasn't the Dark Masters but an existence neglected by the world who allowed the Dark Masters to gain their power. The Chosen Children were then sucked into Subspace, where Gennai contacted them through Koshiro's computer in Episode 62, "The Final Dark Digimon". He explained the Chosen Children had not defeated the root of all evil, and recited them inscriptions found in the Ancient Dino Ruins: something had appeared behind the "Wall of Fire" a long time ago. Its existence distorted space-time and brought a crisis to the world and the power of Digimon was not enough to stop it until a group of Chosen Children from the Real World destroyed it. The inscriptions also had a prophecy: a great darkness would appear from the Wall of Fire once more, the Chosen Children's true enemy. Gennai's transmission then cut off, though not before telling the Chosen Children not to lose heart.

In Episode 63, "A New World", after Andromon asked for a commemorative photo, Gennai started practicing his smile for it, as he hadn't taken a photo in a while, but he instead looked like he was frowning and mad.

After the Chosen Children decided to take another adventure, Gennai and Centalmon confronted them about the solar eclipse. They explained that it was the gate back to the Real World and it'd close in around two hours. While the Chosen Children were fine waiting for the next one since they had 110 years of summer vacation left, Gennai explained that the time difference between the worlds was caused by Apocalymon, and with them gone, both worlds' time were now the same. If the Chosen Children stayed, the world may consider them foreign objects and delete them. Gennai then rushed them to get into the trolley as there was no more time.

Gennai, alongside the Partner Digimon, contacted Taichi and Koshiro in Episode 64, "Our War Game, Beginning". Gennai confirmed if they knew about the new Digimon on the Internet. While Taichi didn't know what to do about it, the Partner Digimon offered to go into the Internet to stop it. Gennai then sent the Digimon in.
