Digimon Tamers: Brave Tamer is the fourth and final game in the Digimon subseries for the WonderSwan, and is consequently the one which concludes the story, ties together the Digimon Adventure and Digimon Tamers continuities, and finishes explaining who the hell that Ryo Akiyama guy is anyway.
After the end of the last game, Ryo is awakened by Monodramon, a small dragon Digimon, in a primitive jungle. Monodramon takes him to confer with ENIAC, the first electronic computer, the Digital World's first overseer, and the origin of the many different alternate Digital Worlds, able to access them in enclosed timeloops in order to prevent any changes to the timeline.
Meanwhile, Millenniumon has since been flung into the future and evolved into its final form, ZeedMillenniumon, and wielding the power to manipulate time and space, is now bent on conquering every timeline and dimension. Each of them resist his power however, so he begins to assemble an army. He notices the existence of ENIAC, and so sends a few mooks to test its defenses. In response to the impending attack, ENIAC assigns Monodramon as Ryo's partner to fend of the invaders, and that's when the fun begins...
The game plays similarly to the previous game, as a simplified Turn-Based Strategy game. Each side can control at most three Digimon, and each turn Digimon can only make a single move. The novelty, like that of the concurrent anime, is the card system: cards containing the data of a Digimon's abilities can be bought or obtained from other Digimon, and can be used in battle to summon an attacker, heal, induce or remove status effects, and out of battle to upgrade a Digimon.
Tropes present in Digimon Tamers: Brave Tamer:
- All There in the Manual: This is the fourth and final part of Ryo's unexported manual.
- Big Bad: ZeedMillenniumon, again. Less expected is the revelation in this game, together with the previous ones, that Milleniumon is also The Unfought Big Bad of both Digimon Adventure and Digimon Adventure 02. For the sake of space, how this is so is explained on the Synopsis page.
- Bittersweet Ending: Monodramon, Ryo's partner Digimon for the duration of Brave Tamer, does a forced Jogress with Millenniummon to prevent him from achieving his goal of forcing Ryo to accept him as his partner or for everyone else to face oblivion if he doesn't comply. Though Monodramon does return, it is as the Ax-Crazy Cyberdramon who can lose control and, without Ryo's supervision, one day return as Millenniummon. At the same time, it could also be considered bittersweet for Millenniummon himself in that he fails in his bid to conquer existence, but does indirectly succeed in his other underlying goal of becoming Ryo's partner.
- Canon Immigrant: This is the game that explains how Ryo is one to begin with.
- Downer Ending/Reality Ensues: Millenniumon, in all his forms, is a massively powerful Eldritch Abomination that controls time itself. How do you defeat something like that? You don't; you drive him off, seal him away and just generally stall until something powerful enough comes along.
- Evil Knockoff: The Dark Tamers are this to Taichi, Daisuke and Takato, and their nine VR Digimon (VR-Apocaly, VR-Omega, VR-WarGrey, VR-Imperial, VR-Venom, VR-BlackWarGrey, VR-Duke, VR-SaintGargo, and VR-Sakuya) are this respectively to Apocalymon, Omegamon, WarGreymon, Imperialdramon, VenomVamdemon, BlackWarGreymon, Dukemon, SaintGalgomon and Sakuyamon.
- Good Counterpart: Monodramon is the opposite of ZeedMilleniumon in almost every way.
- Heroic Mime: Throughout the game Ryo is not particularly talkative, unlike in earlier games, and it is in fact ENIAC who recalls his past. Given the trauma of his experiences in the previous game, this may be justified.
- Luke, I Am Your Father: ZeedMillenniummon finally reveals the reason he respects and praises Ryo the way he does. He claims to be Ryo's "true" partner.
- Multiverse: This game establishes and defines the Digimon franchise as one instead of a string of alternate continuities.
- Multiversal Conqueror: ZeedMillenniummon, to an extent never seen before or again in the franchise.
- New Game+: When doing this, you get to keep all the cards gathered in the previous game, and are given a new one with an... interesting effect: you can play as ZeedMilleniumon by equipping it to Cyberdramon before it evolves.
- Shown Their Work: ENIAC really was the first proper electronic computer, and the Atanasoff-Berry computer really was its rudimentary predecessor.
- Trauma-Induced Amnesia: Although it is not clear if it is simple amnesia or deliberate repression on Ryo's part.
- Why Don't You Just Shoot Him?: As Ryo becomes more and more powerful, one of ZeedMilleniumon's Skull Satamon subordinates outright demands to know why, with all of his vast power, he doesn't just atomize Ryo.
