Pokémon Masters will soon see a fresh sync pair join its growing roster of trainers and pocket monsters: Caitlin, one of the Unova region's Elite Four, and Reuniclus, the final evolution of psychic Pokémon Solosis.

Caitlin and Reuniclus will make their debut on Halloween, October 31st, 2019. Players who want to add the duo to their collection will be able to get their chance with the Spotlight Scout feature. This pair made their debut in Pokémon Black and White as part of the Elite Four, and they even reprised that role in Pokémon Black 2 and White 2.

In a presser released by Nintendo, Caitlin was described as a young lady who "overcame her past weaknesses and became a stronger Trainer." As for the gooey Reuniclus? "They use psychic power to control their arms, which are made of a special liquid. They can crush boulders psychically." Of course, they can.

No matter how many Pokémon Caitlin brought with her in any of the battles across either title, Reuniclus always made its way into her team composition. The psychic Pokémon proved formidable in the face of mismatched types, though veterans of the franchise know that's almost always the case with the creatures sent out during throwdowns with any member of the various Elite Fours.

Pokemon Masters

Since launching in August of this year, Pokémon Masters has been a really strong success in terms of both money-making and reception. In its first month, Pokémon Masters made more than $33 million. As for how players feel, the title currently boasts a 4.7 out of 5 on the App Store with an, albeit lower, 3.6 out of 5 on Google Play. In the case of Android user reviews, the complaints are levied at the truncated story (releasing over time, of course) and how the game pushes players to spend money through difficulty spikes.

Unfortunately, the mobile title has also seen its days of negative feedback, server trouble, and game-breaking bugs. Those problems have persisted enough that developer DeNA had the game's producer, Yu Sasaki, take to the official blog and apologize. It was there that the developers promised to address the lack of content, lack of interesting rewards, poor design, and usability issues. That post came on October 9th, 2019. In an industry that can often avoid offering up outright apologies, the words from developers were certainly welcome. If that production plan is put in motion and Pokémon Masters becomes a better game, then the title will likely make a lot more money in the future.

With all of this in mind, one would have thought Pokémon Masters would see a more ghostly duo drop on Halloween. Maybe next year.
