Disambiguation entry for a series of four Bandai UsefulNotes/WonderSwan games released between 1999 and 2001 based on the ''Franchise/{{Digimon}}'' franchise. The four games star '''Ryo Akiyama''', a character who made a handful of cameo apperances in ''Anime/DigimonAdventure'' and ''Anime/DigimonAdventure02'' before becoming a SixthRanger in ''Anime/DigimonTamers'', and detail his ongoing conflict with the sinister '''[[MultiversalConqueror Millenniumon]]'''. Their main draw is they are [[AllThereInTheManual the hypothetical manual]] for exactly who the hell Ryo is, what he's doing in two different [[AlternateContinuity alternate continuities]], and why he's seemingly out-of-place in the ''Tamers'' universe; they also link together all permutations of the franchise as a {{multiverse}}, which of course Ryo ends up saving.

All four were a victim of NoExportForYou because the UsefulNotes/WonderSwan itself wasn't released in the west, and so while most people are aware they exist and they explain Ryo's backstory, non Japanese fans who've played them or are aware of how exactly it all unfolded are few and far between.

The series did a crossover with ''Manga/{{Digimon V-Tamer 01}}'' in one of its bonus chapters, with Ryo teaming up with the manga's Taichi Yagami to challenge Vikemon... and getting [[HotBlooded very distracted]].

This page exists mainly because it's a damn sight easier to link to this one page than it is to link to all four games at once. Which happens really often in pretty much any mention of Ryo.
