"Welcome! This is the portal that leads to the world of Pokémon!"
The first entry (or rather, entries) in the roguelikePokémon spinoff series known as Pokémon Mystery Dungeon, Red Rescue Team and Blue Rescue Team were released for the Game Boy Advance and Nintendo DS (respectively) in 2006.The story concerns the player character who awakens in a world inhabited exclusively by Pokémon, with no memories but their name and the subsequent discovery that they've inexplicably been transformed from a human into a Pokémon. Natural disasters (earthquakes, etc.) have been plaguing the land, and concerned citizens — er, Pokémon — have been banding together in "Rescue Teams" to help out Mons in need. The player quickly allies with another Pokémon to form a two-Mon rescue team of their own, while slowly piecing together clues about how and why they got here.
Apocalypse How: Via Colony Drop; something between Class 4 - Class 6 is implied. Or possibly Class X, if Xatu's prophecy is to be taken literally.
Badass Normal: Most rescue teams probably qualify as this, as most of them are "normal" relative to each other.
Brick Joke: Upon entering Silent Chasm for the first time, Jumpluff states there is a terrifying monster deep within, which causes your Partner to fake a stomachache. Regardless what you choose, before the next mission, when Alakazam states how dangerous Mt. Thunder is you can fake a stomachache as well, which your Partner jokes to Alakazam, "My friend does this a lot, kind of embarrassing"
Actually, they mention why they're doing rescues: Every mission gives them more money and influence in the eyes of society. Your team shuts that down pretty quickly, though-Meanies stops being a threat post Mt. Freeze.
Covers Always Lie: The covers have the various members of both Team Meanies and Team ACT surrounding what appears to be the main characters. In the game, Team ACT are one of the good guys while Team Meanies are Card Carrying Villains.
Except late in the game Team ACT has to hunt you down, so its more of covers always spoil.
Also, for some reason, one member is swapped out for the member of the other team on each box-it features Gengar being in Team ACT (which would make it Team AGT) and Charizard in Team Meanies.
Easter Egg: As shown as the page image, if you stand the two game boxes on top of each-other (GBA being on the bottom respectively) it shows the two images to connect as one large image.
Event Flag: Usually major events in the plot are triggered by doing a certain number of missions.
Everyone Is Bi: Genders were (largely) missing for some reason. (Your Player Character is still identified as the gender you choose.) Thus, gender-based moves (like Attract) worked on any and every opponent Pokémon.
Prophecy Twist: Ninetales predicted that when a certain human was reborn as a pokemon, the world would be put in danger. However, she never said he was the cause, nor that the two events had any relation to each other besides happening at the same time.
Purely Aesthetic Gender: Subverted. Gender DOES affect the pokemon you turn in at the end of the quiz. Furthermore, there are gender exclusive pokémon. They are pretty much ignored the rest of the game, however.
Wham Line: Gengar: "Kekeh! And that human is the rotten coward that abandoned Gardevoir, correct? I don't think the human can complain about anything if we get rid of it. Isn't that right, (Player Name)?"
Video Game Settings: Most of the dungeons fall into one of these categories: (Listed in order of apperance)
You Are Worth Hell: In a postgame event, Latios is so desparate to locate his younger sister Latias in Pitfall Valley that he doesn't care if he becomes lost forever in it himself, so long as the two of them are together. About the only thing stopping him is that you tracked down and defeated him in battle first.
