Mythical & Shiny Batomon in Batomon Showdown — How to Get Them

What are Mythical and Shiny Batomon?

Mythical is a rarity tier above Legendary; Shiny is a per-monster variant with its own stats. The Batopedia keeps a “???” tab “for event Batomon and mythicals”, and one route appears in official store media: the Gamer trainer, “Gain a Mythical monster on day 9”. All other routes are player accounts, labeled as such below.

The Mythical tier in the official record

Three pieces of the official record define the tier, and together they place it above everything the regular shop sells:

So the regular ladder ends at Legendary, and Mythical arrives from outside it — the ??? pool, event conversions and trinket promotions are where the record places it. The Event monsters that share the ??? tab are officially day-tagged, too: 1.1.0 calls Talonite ‘a day 6 event Batomon’.

What the record never does is name which monsters are Mythical. The ??? tab exists only in-game, no patch note or store page enumerates it, and this site does not guess — the monster list tracks every officially named Batomon and grows as the ??? tab gets verified in-game.

Shiny Batomon and the Trophy, Medal and Star stickers

The April devlog defines three achievement stickers shown beside every Batomon in the Batopedia:

The Star is where the game officially acknowledges Shinies: win a championship with the Shiny version and the card keeps a star. The inspect panel carries a dedicated SHINY button under its level selector, visible in the game’s own store screenshot:

Shiny variants carry their own numbers wherever the patch notes touch them:

That last row is the clearest evidence a Shiny is a mechanically distinct variant rather than a palette swap: the same hotfix cut one form’s cap and left the other’s alone. The Medal definition ties the sticker chase to levels as well — a championship win at level 3 or higher — which is the territory of the leveling guide.

How do you get a Mythical Batomon?

The Gamer trainer is the one route the game itself advertises. The trainer-select screenshot on the official Steam store page shows the card in plain text:

That is a first-party promise, not a player theory — but the community’s September trainer board still grades Gamer poorly, and the trainer tier list carries the whole argument. The short version: the promise arrives late and demands survival until day 9. One commenter’s entire case is the timing — ‘F tier… day 9???’; a kinder vote says ‘at least B, maybe A. If you can just stay alive until you get a mythic you can usually convert it into a win’; the board’s top-rated objection: ‘even when you hit the mythic, a lot of them don’t even stabilize you. I’ve limped into day 9, hit goldora or riglord, and my runs just end’.

Everything beyond Gamer is a community account. The routes below converge in one thread that asks, flat out, ‘is Gamer the only way to get Mythicals in the game?’ — none has been reproduced in a documented run on this site:

One variant has an official hook worth noting: the Masked Man’s card, visible in the same screenshot above, reads ‘Every 4 days, choose a trainer and gain their ability’ — and one player’s verdict, ‘masked man is basically gamer but better’, treats that as a second door into Gamer’s ability. The mechanism on the card is official; using it as a Mythical route is a community read.

The names that surface when players discuss the day-9 pull — Cosmivore, Goldora, Riglord, Riglet, Omnichrome, Aerophim, Faebloom — are community vocabulary too. They come from run reports in the same threads (‘I’ve limped into day 9, hit goldora or riglord’; the Cosmivore showcase that opened the thread), and no official source has matched any of them to the ??? tab yet. They are recorded here as search aids, not as a confirmed Mythical list.

How do you get a Shiny?

The record defines Shinies by their finish line, not their start. A Star sticker is earned ‘for winning a championship with a Shiny version of that Batomon’ — so Shinies exist per monster, they can carry a run to a championship, and they bring their own numbers (table above). How one enters a run in the first place appears in no patch note, devlog or store description. The community’s Shiny threads are showcases of Shinies players already found, not farming guides, which matches this site’s read that no verified method exists to publish.

The most-watched Shiny content treats it as the endgame ceiling: Retromation’s ‘Shiny Level 4 Mythic is Obviously Busted!’ stacks a Shiny onto a Level 4 Mythic — the Level 4 half of that combination is what the Level 4 guide maps from the official side.
