A Message from the Pokémon Masters EX Team (Vol. 17)

Greetings, Trainers. We’re the producers of Pokémon Masters EX, Yu Sasaki and Tetsuya Iguchi, here with a new message for you. Today, we’ll tell you about updates leading up to the one-and-a-half-year mark of the game in late February and preview our plans for the two-year anniversary.

Updates Leading Up to the One-and-a-Half-Year Mark of the Game

A Hoenn Region Sync Pair Gets 6★ EX Unlocked
In conjunction with the Team Hoenn Unite! event, which will be under way on January 17, 2021, a Water-type sync pair from the Hoenn region will get 6★ EX unlocked.

Mallow & Tsareena Debut

Mallow & Tsareena will debut in the sync pair scout on January 20, 2021. At the same time, the Blissful Bonanza! will return. Rewards available for exchange from the Blissful Bonanza! will include 5★-Guaranteed Scout Tickets, lucky scrolls, and other items, so we hope you give this event a try.

Valentine’s Day Story Event

On January 28, 2021, a Valentine’s Day story event will begin. One of the sync pair scouts accompanying this event will feature Serena & Whimsicott in a Valentine’s Day outfit. Another sync pair in a Valentine’s Day outfit will appear as well, so we hope you look forward to their reveal! The new sync pairs in Valentine’s Day outfits will appear in this event giving out sweets, so it’s sure to be a special story.

Egg Event and Improvements to Egg Events
The Fighting-, Grass-, and Rock-Type Egg Event will begin on February 3, 2021. In this event, you’ll be able to get Eggs that can hatch Machop, Bellsprout, or Aerodactyl. Also, after taking players’ feedback and the state of the game into consideration, we decided that starting with this event, areas in Egg events will no longer require stamina. In addition to this, Egg events will no longer offer level-up manuals, coins, or other battle or completion rewards besides Eggs. We appreciate your understanding.

More information will be provided via an in-game notification to be sent at a later date. The Battle Villa will also open on February 3, 2021, so we hope you enjoy both of these opportunities.

Legendary Event: Lurking Shadow Returns
The Lurking Shadow legendary event will return on February 7, 2021. From this event on, Giovanni & Mewtwo’s Custom ★ Power-Ups will be obtainable from the prize box.

This event has been held a few times, so players who have already completed it will be able to get Custom ★ Power-Ups without having to complete the story again and can get them from the prize box instead of as completion rewards.

Run-Up to 1.5 Years Rally
As a sign of our appreciation for your continued support, we will begin a log-in bonus, mission bingo, and more as part of our Run-Up to 1.5 Years Rally starting on February 10, 2021. Be sure to log in and check it out.

Legendary Event: Give and Take
The new Give and Take legendary event will begin on February 10, 2021. In this event, the Legendary Pokémon Xerneas and Yveltal will appear. Each forms a sync pair with a Trainer who might be a little unexpected, so try to guess who their partners might be.

You’ll be able to add one sync pair from the event to your team. The other will appear in the sync pair scout. Just like with returning legendary events, from this event on, you can get 20 Custom ★ Power-Ups for the sync pair that joins your team—and raise their move level to 5★.

Update for the One-and-a-Half-Year Mark

This year, February 25, 2021 will mark one and a half years since the release of Pokémon Masters EX. We have many festivities prepared to celebrate the occasion in late February, and we’ll tell you about some of them today.

Present for the One-and-a-Half Year Mark
Just like with the winter holidays and New Year’s, we’ll be sending a present to all players to show our appreciation. Be sure to log in and collect it.

6★ EX Unlocked for Skyla and Korrina
The winner of last year’s 6★ EX Sync Pair Poll Rally, Skyla, as well as the third-place finisher, Korrina, will have 6★ EX unlocked. The second-place finisher, Barry, will get 6★ EX unlocked at a later date, so stay tuned.

Also, the 6★ EX Skyla Sync Pair Support Rally is now under way. From this rally, you can get the ★ Power-Ups necessary to raise Skyla & Swanna to 6★ EX, so don’t forget to log in every day and complete the missions.

New Type of Poké Fair Scout
A new type of Poké Fair Scout will debut, and this time it will feature a sync pair with unprecedented capabilities. Do note that the offering rate for this scout will be different from that of normal Poké Fair Scouts. Stay tuned for more details in our next message.

Sync Grid Update
Late February’s update will bring changes to improve the usability of the sync grid. We’ve received many requests for a feature that allows you to make multiple selections at once, and we’re pleased to be able to bring that feature and more to you with this update.

The development team has worked to ensure the quality of these new features. Please see the list below for the features that will be implemented with this update.

• A multiple-selection feature for the sync grid.
• A preset feature, which will allow you to save multiple grids with unlocked tiles to be applied right away.
• A feature that will allow co-op sync orbs to be used without converting them to sync orbs.
• Coin-free sync grid resetting.
• A feature to reset tiles individually.
• An additional display for tiles that have move level requirements.
• Pinch-to-zoom functionality.

Plans for the Two-Year Anniversary

We’d like to give you a sneak preview of some of our planned updates for the game’s two-year anniversary.

Additional Chances to Team Up with Sync Pairs
Similar to legendary events, we’d like to add more chances for you to team up with sync pairs just by playing the game.

The Main Story’s Conclusion and a New Story’s Beginning
The current main story will reach its conclusion at the two-year anniversary. Moving forward, we’ll be updating the main story about once every one to two months, so we hope you enjoy how the story unfolds.

After the main story is completed, a new story unique to Pokémon Masters EX will begin—and with a new format. More details on this will be available at a later date. We’re working hard to ensure this will be something all players can enjoy, so we hope you look forward to it.

Dynamax in Development
Finally, for the two-year anniversary, we are working to bring you battles that have Dynamax Pokémon. With this feature, we hope to provide a new way for players to enjoy battles. More details will be available at a later date, so stay tuned.

What to Expect in the Next Message

Our next message is scheduled for mid-February. In our next message, we hope to share details about our update for the one-and-a-half-year mark of the game. We’re always working hard to deliver updates and improvements that make the world of Pokémon Masters EX as fun as possible.

Until next time, thank you for playing Pokémon Masters EX.
