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 closest thing to an enumeration is unofficial: the fan-maintained Batodex database lists a Mythical group — Aerophim, Cosmivore, Faebloom, Goldora, Omnichrome, Rigalord and Riglet, alongside placeholder entries literally named ‘NULL-00’ and ‘MissingN.’ — which matches the community’s day-9 names almost one-to-one. A fan database is not official text (and those NULL placeholders are a good look at why), so the roster stays unverified on this site. One name from it is now officially real, though: patch 1.2.0’s bugfix list mentions ‘the monsters a Rigalord devoured’ — official spelling Rigalord, not the community’s ‘Riglord’. The monster list tracks every officially named Batomon as the record grows.

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:

Those last rows are the clearest evidence a Shiny is a mechanically distinct variant rather than a palette swap: one hotfix cut the normal Sukoi’s cap and left the Shiny’s alone, and patch 1.3.0 (October 6, 2026) fixed Shiny Wishwash “being no better than the regular Wishwash at level 4” — official confirmation that the Shiny form is supposed to be different at max level, in both directions the record now documents. 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’.

Patch 1.2.0 (September 30, 2026) then upgraded the promise’s transparency: the Gamer “now tells you which Mythical it will give you from the start of the run, and you can inspect it from the trainer panel” — official QoL text. Knowing the target before day 1 changes the route’s planning math, though not its timing problem.

Everything beyond Gamer and Mystic Incense 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?’ — and two of them have since been sighted a second time outside it: the shop-spawning trinket read aloud from its own item text on Retromation’s stream, and the ticket upgrade in a separate run report. 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, and, less confidently, Seraphim — are community vocabulary. They come from run reports (‘I’ve limped into day 9, hit goldora or riglord’; the Cosmivore showcase that opened the thread), and one reply on the trainer board grades six of them in a single breath: ‘Riglet is great but needs 1 round to absorb your batomon, Omnichrome is great but has high CD, Aerophim is great but is rng, Cosmivore is just too slow in scaling and works better with money builds, Goldora is ass at lv 1, Faebloom is only good for spawning more mythic items.’ Three of those names now have official or near-official standing: Rigalord is officially spelled and named in patch 1.2.0’s bugfix list (‘the monsters a Rigalord devoured’); Aerophim is named in patch 1.4.0’s bugfix list (adjacent-slot behavior, covered on the Aerophim page); and the fan-maintained Batodex database lists the whole Mythical group the community names — Aerophim, Cosmivore, Faebloom, Goldora, Omnichrome, Rigalord, Riglet — as unofficial, unverified data. Seraphim is the shakiest of the set: cited once as ‘probably the mythical that rerolls the creature and gives it multicast, forgot it’s name’, and absent from the fan database’s Mythical group entirely. No official source has matched any of these names 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 — but two anecdotes now point the same direction: the trainer board’s note that Lucky Girl is ‘Shiny-focused’ (‘for some Batomon it legitimately makes them FAR stronger’), and a player in the Mythics thread who ‘managed to snag a couple shinies with a lucky girl run’. Two data points make a lead, not a method. One more reason to treat Shinies as mechanically distinct: a September build thread notes the Shiny plane ‘buffs the whole shop instead of just next bought’ — a behavior difference, not just a stat one.

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.
