Pokémon Champions Just Dropped a Mobile Bombshell — and the Switch Update Is Already Patching the Chaos

Pokémon Champions is now available on mobile devices, and yes, the battle arena has officially escaped the living-room couch and sprinted into your pocket like a Pikachu that just saw an outlet at 30% battery.

But this is not just "hey, it's on phones now, go touch grass less" energy. The Switch version of Pokémon Champions has also been updated to Version 1.1.0, bringing in new competitive content, more usable Pokémon, held items for Regulation Set M-B, and fixes for visual and network issues.

In other words: the game got bigger, smoother, and slightly less likely to act like it has never seen Wi-Fi before.

According to the official patch notes via Nintendo's support page, the update was released on 16th June 2026. Here is the whole deal, translated from "corporate patch-note whisper" into full human panic mode.

Pokémon Champions Version 1.1.0: The Patch Notes Are Small, But the Impact Is Not

The official update heading is simple, almost suspiciously simple:

Pokémon Champions: Ver. 1.1.0 (16th June 2026)

The following updates have been made to the game.

• Pokémon and held items added for Regulation Set M-B.
• Other fixes to the visuals during battles and certain network-related issues.

That is the entire official patch-note sandwich: bread, meat, bread. But inside that tiny little update description is a surprisingly important move for Pokémon Champions as a competitive battle title.

First, the game adds Pokémon and held items for Regulation Set M-B. That matters because competitive Pokémon formats live and die by rulesets. Regulations decide what Pokémon are legal, what items are legal, and what kind of chaos is allowed to enter the battlefield wearing its little digital sneakers.

Second, the update includes fixes to visuals during battles. That is the polite way of saying: "Some things may have looked weird, glitchy, cursed, or like the battle renderer had a tiny existential crisis."

Third, it fixes certain network-related issues. That is the polite way of saying: "Some people may have been battling through a digital swamp."

And fourth, because the mobile launch is happening today, this is not merely a Switch update. This is a platform expansion moment. Pokémon Champions is now on iOS and Android, which means your battle team is no longer chained to the TV, the dock, or the sacred couch position where your snacks live.

Pokémon Champions Mobile Launch: Raichu, Mega Stones, and Free Loot in Your Mailbox

As part of the Pokémon Champions launch on iOS and Android devices today, there is a special gift waiting for players.

And it is not a coupon for 5% off a digital hat. No, this is actual battle candy:

• Raichu
• Raichunite X
• Raichunite Y

Those items are the Raichunite X and Y Mega Stones, and you can find them in the game's mailbox when you log in during the event period.

That is a very Pokémon move: "Welcome to the game, here is a mouse with electricity trauma and two shiny rocks so you can make it even more unhinged."

For anyone who has been away from the franchise for a minute, Mega Stones are tied to Mega Evolution, a mechanic that lets certain Pokémon temporarily transform into a powered-up form during battle. The Raichunite X and Raichunite Y stones specifically connect to Raichu's alternate powered-up forms.

So yes, if you are jumping into Pokémon Champions mobile today, you are not starting completely empty-handed. You are starting with Raichu and the tools to make that Raichu feel like it just found out electricity has a premium subscription tier.

Why the Mobile Launch Matters

The arrival of Pokémon Champions on mobile devices is a big deal because it changes how the game can be played. Switch battles are great, obviously. The Switch is a powerful little battle brick. But mobile support means the game can follow you into the places Switches usually do not go: quick commutes, lunch breaks, waiting rooms, and any situation where you suddenly need to win a Pokémon battle before your coffee gets cold.

It also lines up with what was previously mentioned: the plan was to expand the Pokémon Champions roster over time. That means today's update is not just a patch. It is part of a broader rollout strategy.

More Pokémon. More items. More formats. More reasons to say, "Just one more battle," and then accidentally lose track of time like a responsible adult who has been defeated by tiny monsters.

The Technical Breakdown: Regulation Set M-B, Held Items, and What That Actually Means

Okay, let's slow down and explain the nerdy stuff without turning this into a lecture from a professor who wears sandals with socks.

The update adds Pokémon and held items for Regulation Set M-B. That sentence sounds small, but it is doing a lot of heavy lifting.

What Is a Regulation Set?

In competitive Pokémon, a regulation set is basically the rulebook for what is allowed in battle. Think of it like a bouncer at a nightclub, except instead of checking IDs, it checks whether your team is legal.

A regulation set can affect:

• Which Pokémon are allowed
• Which held items are allowed
• Which battle formats are active
• Which strategies are viable

So when Pokémon Champions Version 1.1.0 adds Pokémon and held items for Regulation Set M-B, it means the game is opening the door to a new competitive configuration.

That can completely change the meta. One day your favorite strategy is king. The next day, the rules update walks in wearing sunglasses and says, "Not anymore, cowboy."

What Are Held Items?

Held items are items that a Pokémon carries into battle. They are not consumed like potions. They sit there quietly, like a tiny backpack goblin, waiting to change the outcome of a fight.

A held item might:

• Boost an attack
• Improve defense
• Restore health
• Change speed
• Enable specific strategies

In competitive play, held items can be the difference between "I have trained for weeks" and "I just got folded like laundry by a Pokémon holding a berry."

That is why the Regulation Set M-B update matters. It is not just adding flavor. It is adding tools. It is adding counters. It is adding new ways to build teams and new ways to ruin someone's day in the most adorable possible format.

What About the Visual and Network Fixes?

The patch notes also mention fixes to visuals during battles and certain network-related issues.

Visual fixes are important because battles are the whole point of the game. If animations glitch, effects disappear, or the screen does something weird during a critical moment, that is not just annoying. It can affect readability and competitive clarity.

Network fixes are even more important. Online battles are basically a handshake between two devices, two game clients, and whatever cosmic Wi-Fi spirits are currently awake. If that connection stutters, battles can lag, disconnect, or behave badly.

So yes, "network-related issues" sounds boring. But in online battle games, it is the difference between "clean victory" and "ARE YOU KIDDING ME RIGHT NOW, MY CONNECTION JUST LEFT THE BUILDING."

Cross-Save Support: Your Pokémon Champions Progress Can Now Jump From Switch to Mobile

Here is the feature that makes the Pokémon Champions mobile launch feel like a proper platform expansion instead of a cute side experiment:

The mobile version includes cross-save support.

That means if you have been playing on Switch or Switch 2, you can continue battling on your mobile device.

That is huge. Not "my toaster has Bluetooth" huge, but "my entire competitive identity is now portable" huge.

Cross-save support changes the rhythm of the game. You can start on console, continue on mobile, and keep your progress intact. No weird manual transfers. No "oops, your save file is trapped in the TV dock dimension." Just continuity.

For competitive players, that matters because momentum is everything. If you are testing teams, grinding battles, or trying to understand the new Regulation Set M-B landscape, being able to jump between devices is extremely convenient.

For casual players, it means you can play wherever life happens. And let's be honest: life happens in inconvenient places, usually when you are holding groceries and pretending you have everything under control.

Switch, Switch 2, iOS, and Android: The Battle Field Is Expanding

The update and mobile launch together make Pokémon Champions feel more flexible. The Switch version gets updated. The mobile version launches. Cross-save connects the experience. The roster expands over time. New gifts appear during the launch event.

That is a much bigger picture than a single patch note.

This is the game saying: "We are building a live competitive ecosystem, and we would like your entire Pokémon team to please stop loitering on one device."

And if you have not tried the title yet, there is now a very easy argument for giving it a shot. Mobile access lowers the barrier. The free Raichu gift adds immediate value. Cross-save reduces friction. The Version 1.1.0 update improves the experience.

Basically, the game just opened more doors, polished a few handles, and handed you an electric mouse with Mega Stone accessories.

Where to Check the New Usable Pokémon and Items

For now, the article notes that you can check out the new usable Pokémon and items on Serebii.net.

That is useful because patch notes often tell you what changed, but not always the full "what does this mean for my team, you beautiful disaster" breakdown.

If you are trying to understand the new Pokémon Champions Regulation Set M-B additions, Serebii.net is the place to look for the updated usable Pokémon and items.

That matters because competitive players do not just want a list. They want implications. They want to know what is legal, what is banned, what is weird, what is broken, and what is hiding in the corner waiting to destroy the current meta like a raccoon in a server room.

The update also reinforces the previously mentioned plan to expand the Pokémon Champions roster over time. That means today's list is not the end. It is a checkpoint.

And in live-service competitive games, checkpoints are where the internet starts arguing in capital letters.

The Big Question: Are You Actually Playing Pokémon Champions on Mobile?

The original article ends with the question that matters most:

Will you be checking out Pokémon Champions on mobile? How about this new game update?

And honestly, that is the correct question. Because this is not just a patch. It is a signal.

Pokémon Champions is now on mobile. The Switch version is on Version 1.1.0. Regulation Set M-B has new Pokémon and held items. Visual and network issues are being addressed. Cross-save is available between Switch, Switch 2, and mobile. And there is a launch gift featuring Raichu plus the Raichunite X and Y Mega Stones.

That is a lot of "new" for one day.

It is the kind of update that makes you say, "Cool, cool, cool," while your old team comp starts sweating in the corner like it just got invited to a job interview it did not study for.

What To Do Before You Jump Into Pokémon Champions Mobile Today

• Log in during the event period. Your mailbox is holding Raichu and the Raichunite X and Y Mega Stones. Do not be the person who misses free loot like a goblin who walked past a treasure chest because it looked "too obvious."
• Update the Switch version. Make sure Pokémon Champions is on Version 1.1.0 if you are playing on Switch.
• Check the new usable Pokémon and items. Head to Serebii.net if you want to see what has been added for Regulation Set M-B.
• Rebuild your team before the meta rebuilds you. New held items can change matchups fast. Your old favorite strategy may suddenly need a glow-up.
• Test cross-save carefully. If you play on Switch or Switch 2, confirm that your progress continues properly on your mobile device.
• Watch for visual and network behavior. If battles look smoother and disconnects drop, the update is doing its job. If not, the Wi-Fi goblins may still be employed.
• Do not sleep on Raichu. Free launch gifts are not always meta-defining, but they are always worth checking before you dismiss them like yesterday's browser tabs.

The Bottom Line

Pokémon Champions has officially expanded to mobile, and the Switch update to Version 1.1.0 makes the rollout feel less like a tiny patch and more like the opening move in a much larger competitive strategy.

The 16th June 2026 update adds Pokémon and held items for Regulation Set M-B, fixes visual and network issues, and supports the game's growing live competitive ecosystem.

The mobile launch brings iOS and Android support, cross-save with Switch and Switch 2, and a special gift of Raichu plus the Raichunite X and Y Mega Stones in the game mailbox during the event period.

So yes, this is a big day for Pokémon Champions. The game is bigger, more portable, and more competitive than it was yesterday.

Now go check your mailbox, update your game, rebuild your team, and then drop a comment: are you jumping into Pokémon Champions on mobile, or are you staying docked like a loyal couch commander? Share this with your battle squad, enable 2FA if you value your accounts more than a chaotic Pidgey values personal space, and may your connection be cleaner than your opponent's excuses. 🔥
