Special Research
A Special Research was made available since March.

Hey there, TRAINER! It’s good to see you. As you know, I’ve recently been conducting research on several different regions in the world of Pokémon. Along the way, I came across some books that collected stories and legends from various regions. One of these tomes told of three Legendary Pokémon from the Unova region—a trio that seem to be capable of changing formes. Needless to say, that piqued my interest, and I became so enveloped in my research that I even began seeing those three Legendary Pokémon in my dreams! Which brings me to why I called you here. Can you help me with some research, Trainer? I was thinking we could start by catching some Rock-type Pokémon—you know, just to give ourselves a sturdy foundation to build from. ...Get it? Sturdy? Because they’re...Rock-type? A-anyway, I’d appreciate the help. Let’s GO!

Welcome back, Trainer. Now that we’ve established a foundation for our research, we need to narrow our focus. There are three stories I want to investigate, so I think the best approach is to focus on one story at a time and see what we can learn. My hope is to discover as much as we can about these Pokémon, so that when we see clues or signs of their appearance, we’re as prepared as possible! This first story tells of a Legendary Pokémon called Landorus. The story says that lands visited by Landorus yield such bountiful crops that it’s been hailed as “The Guardian of the Fields.” Landorus seems to have two formes: Incarnate Forme, and the very rarely seen Therian Forme. I haven’t been able to find any imagery depicting the latter, but every source I’ve read agrees on its existence! For now, why don’t we research Ground-type Pokémon? Maybe in doing so we can better equip ourselves to identify Landorus’s Therian Forme when the time comes.

Thank you, TRAINER. I think we’ve gained a better understanding of Landorus after studying Ground-type Pokémon. And is that a Drilbur you’ve got there? I dig it! ...Haha! Sorry, sorry. Anyway, since we’ve explored all our leads on Landorus for the moment, what do you say we move on to another Pokémon from my dream? Let’s focus on Tornadus next. The texts say Tornadus expels massive energy from its tail, causing severe storms, and that its power is great enough to blow houses away. Like Landorus, Tornadus also has both Incarnate and Therian Formes. Hmm... Maybe researching Flying-type Pokémon in the area is our best bet for now? Let’s give it a shot, Trainer!

Excellent work, Trainer! Thanks for documenting that information about Tornadus. It seems you even found yourself a darling Ducklett along the way! Is it all it’s quacked up to be? Haha! I think we’ve learned everything we can about Tornadus for now. Its Therian Forme is still a mystery, but hopefully not for long! Before we start investigating the final Legendary Pokémon from my dream, I need to share something...strange. You see, I’d been running myself a bit ragged with research, so I stopped for an afternoon nap. In the resulting dream, I saw those three Unovan Legendary Pokémon again, clear as crystal. But then, the whole dream just started...fading. It was almost like something was eating the dream itself. I’m still not sure what to make of it all, but let's stay on the lookout for anything suspicious. I have a hunch this may be the work of a Pokémon nearby. For now, though, let’s continue our research and turn our attention to the last of the three Unovan Legendary Pokémon detailed in those stories—Thundurus. Thundurus is known as the Bolt Strike Pokémon, and its story also references both Incarnate and Therian Formes. The spikes on its tail are said to discharge immense bolts of lightning. For the sake of consistency, let’s go ahead and research Electric-type Pokémon in the area as we compile our notes on Thundurus.

Ah, there you are, TRAINER. I have something big to share! But first, I want to thank you for all your hard work collecting information on Landorus, Tornadus, and Thundurus. I feel confident that when the time comes, you’ll be prepared to encounter any of these amazing Legendary Pokémon—regardless of which forme they appear in. Now—do you remember that strange experience I had where my dream began fading inexplicably? I think I may have finally uncovered the cause. While consulting the Pokédex for possible culprits, I came across an entry for a Pokémon called Munna. It’s known as the Dream Eater Pokémon—so you can see why it caught my eye! Munna is said to eat the dreams of both people and Pokémon, expelling mist as a result. The mist is pink if the dream is pleasant, and black if it’s a nightmare. I was pretty pleased to be dreaming of those Unovan Legendary Pokémon again, so I suspect Munna’s mist was nice and rosy that day! Munna seems like a fascinating Pokémon, and I can’t wait to research it more. I hope you’ll give me a hand when the time comes, Trainer! Now, let’s GO!
