Gennai (ゲンナイ Gen'nai?) is a fictional character from the anime Digimon Adventure and Digimon Adventure 02 who serves as a guide to the Digital World.


Gennai's name is likely a reference to Hiraga Gennai.


He is a mysterious being that the DigiDestined first encounter after the battle with Devimon. He claims to be data, but without the same attributes as Digimon. Gennai appeared first to the DigiDestined as a very old man, but when Kari 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 chosing the Chosen Digimon. Soon, however, the Dark Masters discovered their plans, and Piedmon, along with an army of Guardromon and Mekanorimon, invaded and destroyed the secret base, killing all save Gennai. Piedmon stole the Tags and Crests, but Gennai interrupted him by attacking him with a sword. Piedmon inserted a mysterious black ball into Gennai before Gennai leapt into a Mekanorimon and kicked the Bakemon driver out—escaping with the Digi-Eggs of the Chosen Digimon and the Digivices. In the process, Gennai dropped one egg — Gatomon's — which later hatched and grew up alone. The purpose of the mysterious black ball was never officially explained on screen or by any members of the series' production staff. Many fans believe that it caused Gennai to age into the old man he was in the first series.

Later, Gennai's secret base became Myotismon's castle.

At some point after Digimon Adventure, Gennai called the DigiDestined 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. In the English dub, Azulongmon, while talking to Gennai says that he is looking youthful; Gennai responds that he has been taking Digi-vitamins.

Throughout the first and second series, Gennai takes a backstage role to helping the DigiDestined. He calls them to the Server Continent to defeat Etemon, he helps them get through Myotismon's interdimensional gate, he gives Izzy a Digital Barrier program, and he tells them of the existence of Apocalymon, the final enemy. In the second series, Gennai resurfaces younger than ever, and aids them during the World Tour arc and caused the 8 original Digimon to regain their ability to Digivolve to Ultimate thanks to one of Azulongmon's powers cores which allows Paildramon to become Imperialdramon. He has counterparts in the locations that the DigiDestined were taken to by Imperialdramon. He appears at the end, returning to Gatomon her lost Tail Ring, whose absence he explains allowed Gatomon to Armor and DNA Digivolve like the others.
