Mameo (マメオ?), originally known as the Black Knit Cap Man (黒いニット帽の男 Kuroi Nitto-bou no Otoko?), is a mysterious man. His true name is unknown, but Luche calls him Mameo because of the Mamemon print on his hat, and he himself adopts the nickname afterward.
Mameo is a young man with fair skin, brown hair and blue eyes. He wears a black knitted hat with a white Mamemon smiley face on it, a yellow and black hooded shirt with long sleeves, black pants with yellow pockets, and black sneakers with yellow soles.
The Protagonist lives in Tokyo with his mother.
One day, he goes to the park and sees his friends playing Digital Monster in a battle between MetalGreymon and MetalMamemon. After arriving home, he finds his mother's note, saying she would arrive home late, and hears a sound coming from his Digimon Pendulum, where a Koromon is calling him. He is then dragged to the Digimon World.
After waking up in the Digimon World, the Protagonist thinks he's dreaming, but then Jijimon tells him it's not a dream, and shows him his Partner. Inside his house, Jijimon tells the boy that he brought him to the Digimon World to save File Island, as its inhabitants were losing their memory. He then asks the Protagonist to take his Partner to explore the island, find the cause of the danger, and get Digimon to come back. The Protagonist then recruits a large amount of Digimon, then goes to Mt. Infinity to confront the antagonist, Analogman and his partner Machinedramon. After defeating them, Analogman attempts to blow up the Island, however he is thwarted by Airdramon and his bomb only winds up causing his own death. Despite this, Analogman is able to return, either in Gray Lords Mansion, Ogre Fortress or Ice Sanctuary - which then transforms into the Back Dimension - with an even stronger Manchinedramon, though ends up losing again. It is then it is found out that the Machinedramon was a fake, created from an ordinary Digimon. This same event happens over and over again in an endless loop.

Mameo never gives his actual name, but everyone calls him 'Mameo' after Luche mentions the Mamemon patch on his hat. He mentions having saved a Digital World before (but not the one featured in Next Order) and as a reward, being able to use the Digital Dive to return as and when he wishes. He also reveals that the area known as the Frost Cathedral was once in the Digital World he saved in the past and was called the Ice Sanctuary there. He and that World's Jijimon had used Jijimon's power to send it away, as it was harbouring a lot of evil and he was surprised to see it had ended up in this World.
He first appears in Server Desert, trying to restore a Gotsumon that had been infected by the BH Program with a basic antivirus, but fails. Shiki/Takuto, Kouta and Himari come across him while he does this, and assumes that he is the human behind the unexplained Machinedramon attacks. After the Machinedramons defeat, he introduces himself and his partner, who is stuck in Digiegg form because of the BH Program infecting it.
Brought back to Floatia, he explains that he was attempting to remove the infection, but failed. He passes on his prototype antivirus to Takuto/Shiki who use the antivirus to cure multiple Digimon until a more powerful form is made. Once Takuto/Shiki defeats Shoma Tsuzuki and Omegamon Alter-B, Mameo mentions that "the man he defeated once before" (Analogman) had been possessing Shoma and that Shoma was not to blame for anything that had happened. Shoma disagreed though, saying he sought out the power and that it was his fault. Mameo then reveals is a teacher in the real world and is Shoma's home room teacher.
Mameo then returns to being a tamer and battles Takuto/Shiki with his reborn Mamemon and his new partner, a Machinedramon. After being defeated, he besots his title of "a Legendary Tamer" to Takuto/Shiki.
