Why does the Player Character talk when he/she is acting? Because they don't talk anywhere else due to the fact the makers wanted you to imagine their personalities, and in Pokéstar Studios they talk because they're acting.
Why the mixed Pokédex? After you beat the Elite Four in Pokémon Black and White, you gain the ability to catch Pokémon from the other regions of previous generations. Since these games take place two years after Black and White, it makes sense that you would still have access to them.
Several of the older Pokémon already confirmed to be present in Black 2/White 2 — such as Eevee, Beldum, and Riolu — were previously only obtainable as gift Pokémon or in the Safari Zone and not available in the wild. Perhaps they are actually native to Unova and imported to other regions?
They weren't available in Black and White, though. It might just be more likely that they were more suited to Unova's environment and so were able to thrive once they were introduced to the region.
Actually, Riolu could be found in Challenger's Cave and Metang at Giant Chasm in the original BW. Eevee is found at a location that was not accessible in the first game.
Also, in the previous game, a Trainer mentions that they are looking for Pokémon that escaped the PokéTransfer Lab. This must mean that the Pokémon escaped, fled throughout the region, and bred. In other words, invasive species are taking over Unova.
One example: the common Pokémon from Kanto, Rattata, isn't in the first routes of the game, but in the sewers.
During the journey, the main character is confronted by the trio of the legendary Knights (Terrakion, Virizion, Cobalion). It is only when, before the final confrontation with Team Plasma, Corless tells him that Terrakion "is looking for a worthy Trainer" that it all makes sense: just like they put an end to a war between Pokémon and humans in the legends, they sensed the calamities that Team Plasma's exploiting of Pokémon would have brought and actively sought a Trainer to lead them against the new enemy. The fact that they're all Fighting type, while one of the types most used by Team Plasma is Dark, makes them even better for the task.
One of the other major types used by this incarnation of Team Plasma? Ice. Which is also weak to Fighting.
Bianca's slight redesign includes glasses. This seems like a somewhat inexplicable addition until you take into account how klutzy she is in the first games - she's nearsighted!
Why is there no Elite Four tournament at the PWT? Because the Gym Leaders and Champions left their home regions to participate in the tournament and SOMEONE has to look after the regions in the event of a disaster.
A slight bit, in the animated video. Bianca shows the protagonist and rival the three Poké Balls that contain the starters. It may just be because it was in the middle, but the camera focuses on the middle Poké Ball, and zooms out to see that the protagonist had his eye on it. Two scenes later, he is revealed to have an Emboar, meaning he chose Tepig, which was in the middle ball in the game version of this scene.
The battle with your rival in Pokémon World Tournament might be seen unfair. I mean, a Lv. 25 Servine using Leaf Blade? Even Snivy can't learn it earlier than at Lv. 28, and no, it's not an Egg move (in the English trailer he claims to raise the starter from an Egg), as it wasn't capable of using it earlier... but then when his Servine was seen in battle once again, few moments after the Pokémon World Tournament, it struck me. The Servine and other Pokémon at his time suddenly gained levels. 33 for starter, 31 for Tranquill and Simisear. Notice how both his, Cheren's and Akuroma's Pokémon were at lv. 25. All three of them... Their actual levels weren't that. They were reduced, like in Battle Subway (though there my Pokémon got increased Level to 50... but you know the drill). It makes sense that it knew Leaf Blade – it was actually at right level! That brings us to a point... which we can discuss here.
But you can pass level up moves to baby pokemon.
Then why he didn't knew Leaf Blade earlier? You can pass them, but you can't make Pokémon learn them earlier.
Could also count as Fridge Horror, but Ghetsis's Hydreigon knows the move Frustration, in these games. Frustration is a move that grows stronger depending on how much your Pokémon dislikes you. Considering who Ghetsis is, it's probably on Hydreigon for a good reason, and probably at max power, as well.
A little disturbing and ambiguously Fridge Horror as well— what would it take to make something as unabashedly violent and evil as Hydreigon hateful enough to use Frustration? Possibly a stealth reconstruction of the idea that Pokemon are mostly good-natured— even Hydreigon has standards.
That same Hydreigon carries a Life Orb, which means that in addition to the above, it's injuring itself every single time it attacks.
Right before the credits start, Iris leads the player out of the Hall of Fame and Champion's room, to the massive staircase. There, the Elite Four members are waiting, and the player walks down the steps and turns to them. Afterward, the player walks forward a bit, and Iris follows. Then, Iris and the Elite Four form the V shape, with Iris at the bottom and two Elite Four members at her sides while the player runs off, and the credits begin. While possibly unintentional, it's brilliant because V could be for Victory (as in, you were just victorious over the Elite Four and the Champion, and Victini is also represented by V and Victory). And of course, this game takes place during Generation V.
Following on from the 'how powerful was the original dragon' Fridge Horror below, it would make sense for the original dragon's stat total/power to rival that of Arceus. The game mythos in Diamond, Pearl and Platinum only ever confirms that Arceus created the Sinnoh region. The mythos surrounding the original dragon says that it created Unova. Both of them created regions of their own, making them equals in power.
Well, the Original Dragon didn't create Unova so much as it did help to establish the region's civilization, but still, it's impressive nonetheless.
The Shadow Triad all have Pawniard (that evolve into Bisharp) because the three of them are Ghetsis' pawns/chess pieces.
Of all the returning Gym Leaders, only Elesa got significantly different sprites, and a radical overhaul of her whole appearance at that. Why only her? Well, her day job is a supermodel. She wouldn't be caught dead wearing two-year-old fashion.
Not to mention she's also the only one who changed her hair color. It's quite possible that she dyes her hair often to go with whatever she's wearing for particular fashion shows.
Why is Pikachu still not in the Unova Dex despite being the anime mascot as Ash's signature Pokemon? All to be consistent with the anime where it was already stated that Pikachu is a rare Pokemon not found in the Unova region!
Why is Cheren a Normal-type Gym Leader? He's gone back to basics!
What's with Sabrina's cameo in Pokewood? Well, look at her design over time. She took a major leap from being semi-formal to quite casual. Think about her for a second. She's intimidating with her strong Psychic Powers, red eyes, and general demeanor. Despite this she's just as good and nice as any of the other Gym Leaders. Sabrina knew she scared people, didn't like this, and decided to change herself. She decided to do a movie to help show she's not as creepy as she seems.. She should have chosen her role better, though.
When you fight the Shadow Triad guy first time, his payout is 180 per level. Next time, his payout is 100 per level, even though the other two you fight in the same place have payout 180 per level. Considering that in Icirrus City, payouts of all three are 180 per level, this can make sense. Why he gives temporarily lower payout? Because he lost to you previously, so he couldn't give as much next time (because players could get from that point to that point in one day, while Icirrus City fights are once per season, so that's much more time).
Colress, the new character to basically replace N. His only interest is bringing out the potential of Pokémon, and he believes this is done by having Pokémon work with trainers. He doesn't care at all about the world going on around him at all. And whereas N had to be convinced that he might be wrong, Colress was always looking for a better answer. In other words, he's the exact opposite to N.
Colress=Colorless. Fits with the black/white theme
When you fight Rood in Driftveil City, his second Pokémon is Swoobat. Woobat evolves into Swoobat through happiness, hinting that Rood has learned to be on good terms with the Pokémon he brings out in battle.
This could even be extended to his other Pokemon: Herdier, the Loyal Dog Pokemon.
Taking a bit of brilliance from the original games page with Golurk on how they were made to stop people from taking Reshiram and Zekrom and stopping people if they caught them. Golurk is now found at the new victory road. In the first game N got the dragon and fought the elite four. Which is near victory road. Maybe, just maybe, they decided to set up shop over there just in case this sorta thing happened again.
Also, what's underneath Victory Road now? N's castle. While N is good now, of course, visiting his castle is how you end up getting Reshiram/Zekrom. If Golurk was really made to stop the dragons, perhaps they're capable of telling that the area has an indirect connection to them.
Why is Burgh's sprite now wrapped up in this cocoon-shawl-type thing? And why does Elesa have this giant puffy yellow coat on over her outfit? And Roxie wears this heavy sweater—it's almost like Unova's gotten inexplicably colder outsi... oooooh.
Possible extra Fridge Brilliance on Burgh: when Cheren gives you the Surf HM, he mentions that some places have been experiencing very low temperatures lately. One of the places he specifically says is Castelia City... No wonder Burgh wears that shawl now.
People wonder why Koga, Fuchsia City Gym Leader from Generation I and its remakes, is not in the PWT. It's because he's not a Gym Leader anymore, he's Elite Four!
Ghetsis tries to freeze the protagonist, with a move that cannot induce freezing in battle.
Possibly; in the promotional video, assuming that what was shown were actual places in the game, the frozen part of Unova was seen intact, no buildings were torn apart or anything, just frozen over. Who is to say that there weren't any people in those buildings?
It seems to happen in the game as well, as Opelucid City becomes frozen over, and the player does chase after the Shadow Triad like in the promotional video. In this case, there were plenty of innocent people who may have been frozen to death.
In the post-game, Opelucid City defrosts, and everyone is revealed to be perfectly fine. That doesn't make it too much better, though, since they were still trapped inside their homes for at least a short time.
(Continued from the fridge page of these games' predecessors.) It is pointed out in the Fridge page for the original Pokémon Black and White under Fridge Brilliance that in those games, Absol can be found around the Giant Chasm, as if it's warning the protagonist to Kyurem's presence. In these games, Absol is implied to have a wider range due to its addition to the Unova Pokédex... and Kyurem is the mascot of both games, in which parts of Unova were frozen over. Looks like Absol felt it had work to do in other parts of Unova — and of course it gets ignored and often scapegoated.
Considering how powerful two of the Tao Trio fused together are (base stat total of 700, behind only Arceus), one wonders how powerful the original dragon was that the three originated from.
The Tao Trio seem to have a "20-point increment" thing going on in regards to their BS Ts, like this: Normal Kyurem (660 BST), Reshiram/Zekrom (680 BST), Black/White Kyurem (700 BST), Original Dragon (720 BST). So following this model, the Original Dragon would seem to be on par with Arceus, as many others have predicted.
On this note, maybe it's a good thing that Hilda/Hilbert never shows up in the game (or at least during the scenes involving Kyurem). Imagine what would happen if Kyurem absorbed both N's and Hilda/Hilbert's dragons... Even if Kyurem is just doing it to be "complete" again and isn't actually going to do anything evil, it would still make for a really tough fight. Also, try not to think too much about what could happen if Ghetsis ever got his hands on the original dragon...
From "G" and "Cis" (C♯), the pitches of the timpanis used in his battle theme. The combination of "G" and "Cis" is a tritone, previously referred to as Diabolus in Musica (The Devil in the Music) in the 18th century. Could also be romanized as Goetis, derived from Goetia, Greek for "sorcery". - This is what Ghetsis's page on Bulbapedia says.
The new Gyms are still perilous.
Skyla's new Gym. A minor case, but one would imagine all of the concussions anyone would receive after being in that gym, being blown straight into the wall, and in the protagonist's case, straight through the gym, smashing two boxes, and out the doors. Worse is, the boxes respawn after reentering. You could keep going up to Skyla and exiting the gym, smashing through those boxes over and over.
Even worse, next time you visit Skyla's gym look whats underneath the grating you're standing on.
Drayden's new Gym. Are the trainers just not afraid of heights? Hell, Drayden himself is at the top of that dragon, although he's pretty Badass, so one would imagine that he'd be okay.
Burgh's new Gym. The cocoon constructions that the player travels through are remarkably thin. What would happen if someone got stuck? Also, the Gym is just one giant hazard for any claustrophobic challengers who go there.
While Ghetsis' right arm has also been obscured by his cloak, N's crowning sequence showed he still had one. Come 2 years later, and we see that not only does he use his cane for support as well as controlling Kyurem, but his Hydreigon knows a full-power Frustration. Does this mean that Ghetsis has become so abusive and evil that his Hydreigon crippled him? If so, what dark power did Ghetsis have to survive the assault and what's stopping Hydreigon from escaping/going on a rampage now that his master is completely insane.
Even worse if you check out the cane that is implanted into the ground after defeating and breaking him. It will say it might have been used to control Kyurem, but what is the possibility that it wasn't just Kyurem Ghetsis was using his cane to control?
Oh, and Hydreigon's got a Life Orb now. Ghetsis is forcing his signature Pokemon to make its attacks even stronger by siphoning off its life force.
In Celestial Tower, there's a School Kid with a Litwick. After you beat her, she says she's feeling all tired after a loss. Then, if you go to the Pokemon Center afterwards, she'll be there. Talk to her, and she'll say that she was feeling a little burnt out, but she feels better now, and that she can do anything if she has her Litwick with her, or something along those lines. Now read Litwick's Pokedex entry.
Made even worse it is her Litwick especially. Even if you own it, the thing still will drain your life energy.
While the rockslide destroying Route 10 is tragic, how many of the wild Pokemon residing there died?
I guess that would depend on how many of them managed to sense the oncoming rockslide and then fled in response.
The Chasm is worse, after the frigate leaves the trees looked knocked down rather than squashed like you would think from the frigate coming down...does this mean Team Plasma bombed the forest just to make a place for them to land?
One of the Ferris Wheel's dates, December, mentions she is constantly on the run from some secret group and cannot seem to stay in one place for very long. She also seems to allude a few details on that they are rather aggressive, want her due to knowing something, and is even afraid of showing her face outside a window. That sounds like Nightmare Fuel and Paranoia Fuel on its own, but then she implies there is a lot more going on. Now think of how worse it will be when Winter ends and she stops showing up. And even if she lives, it still leaves some dark implications behind there are evil syndicates operating in Unova under our noses.
So N was found alone in a forest. While this may seem Nightmare Retardant, there's still the Fridge Horror of why his parents aren't raising him or simply took him to an orphanage:
They were killed, hence why N is stuck in a forest. Consider how young N must have been
Ghetsis is responsible for his parents abandoning him/dying. And given Ghetsis has the same hairstyle as N, he either did some nasty surgery for family resemblance or didn't need to. Which would mean he screwed up or outright killed his own sibling.
When you make a lot of movies in Pokestar Studios, you'll eventually get an elderly woman as a fan. Every time you make a good film, she'll tell you that, "Your last film made me laugh so much, my dentures fell out of my mouth!", even when the movie you just made wasn't a comedy. Is she going senile?
Even movies that aren't comedies can have funny bits.
