These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Breather Boss: The sixth gym leader. He uses Grass-type Pokemon, and since there are loads of Flying-types in Corna (especially in the jungle area before him) he typically goes down without much trouble. It's especially jarring compared to the previous three gym leaders, which are Those Three Bosses.
Fautso. While the choices for ghosts are lackluster before you fight him, use the Fire starter or Tigat and spam Bite. It doesn't help that the latter is common after the first gym.
Crowning Moment Of Awesome: During the Let's Play, Foxy after winning the championship finally gets her katana unstuck and kills her stalker rival.
Special mention goes to Gustano, which was supposed to look like an earthworm but ends up looking like a gigantic slithering sperm instead...
Fridge Logic: The evil team plans to make Electric Pokémon stronger by inflating the sun with a broken ghost detector. Wait, what? This is doubly funny if you consider the move Sunny Day actually makes Thunder less accurate.
Goddamned Mushrooms: Stulo and its evolution Fungio are very fast (making them hard to escape from), use Mean Look to prevent switching or escape, spam bad status moves, and have Effect Spore, which can cause a physical attacker to get either Sleep, Poison or Paralysis. In fact, the hack shows that they are replacements of Zubat and Golbat, even having the exact same cry. Oh, and they can also learn Fly.
Pikish, which is essentially Tentacool with Poison Point. Arrghhh.
Good Bad Bug: The Sprites for the Legendaries don't disappear when you catch them.
Now the gym leader who gives the Legend Badge is the seventh gym leader like Danny as of Black 2 and White 2, and Danny would battle in double battles, while not the gym leader there are two trainers who will battle in rotation and triple battles, and is the only gym to do that in Black 2 and White 2.
The Ice-type gym leader wears fairly inappropriate clothes for living in a cold, snowy area. Sound familiar?
Ramon's hairstyle and bandana are suspiciously similar to the hair and visor the B2W2's male protagonist.
The female protagonist/Foxy/Ran has an uncanny resemblance to Serena of Pokémon X and Y, with a giant ribbon instead of a Nice Hat.
The previews for Pokemon X and Y show the player character using rollerskates to get around.
Team Ambar's plan is to inflate the sun to power up electric-types. Along comes a Gen VI Pokémon, Helioptile, which is an electric-type that gains its power from the sun.
As of Gen VI, the Exp. Share is now a key item that works exactly the way Ba-chan describes it rather than the held item it was in Generations II-V.
You can fight a nurse that will heal your Pokemon she's actually kidding, years before the Doctor and Nurse Trainer Class actually existed in Pokémon Black and White.
Again from Pokémon Black and White, the Tigat line (Dark-typed purple-colored felines) is suspiciously similar to the Purrloin line.
In the deeper area of Mana Nests, there is a strange parallel-with-the-surface water current that requires you to use Waterfall on it. In Platinum one section in the Distortion World has this in reverse, a waterfall-like structure that doesn't require said HM.
The Marblenote heavily edited Kanto starters have another evolution stage following their final forms. Mega Evolutions everyone?
Idiot Plot: The villains are trying to inflate the sun with a broken ghost detector. To power up the Electric Pokémon. Yeah, not the Fire Pokémon or anything.
Iron Woobie: During the Let's Play, Foxy contends with a land filled with rapists, idiots who mangle the English language, an over-abundance of flying-types, a villainous team band with the stupidest goal in the history of the Pokémon world, catching a Babos (seriously, Arceus must have been on some major drugs when he created that thing), a creepy molesting stalker, Groudon and Kyogre's deformed cousins, a Pokémon professor who's a huge creep and a Marty Stu, and gym leaders who have an infinite supply of full restores. She also makes ghosts and pirates cry.
It's Easy, so It Sucks: You can find Master Balls and Olympus Mons Legendaries everywhere very early in this Hack. Slightly justified, in that the gym leaders are ridiculously overleveled and have what seems like an endless supply of Full Restores.
This was in the original beta due to a glitch. The final version pretty much fixes this so that they're rare like they're supposed to be.
Foxy: Roxy once told me secretly that her friend Misty wasn't a very nice person. I dunno about that though... I think she's kind of cute!
Foxy also refers to a number of other female trainers as "cute" during her travels, the comment being accompanied by a "lovestruck" emoticon each time. Given both this and her "no wonder I like girls more than guys" comment after J. Akira forces her to kiss him, Foxy seems to be a lipstick lesbian, which is hardly surprising given Akira's unwanted advances and her penchant for interpreting virtually EVERY male around her as a creepy potential rapist.
At one point she encounters this◊ female trainer and says:
Foxy: Your legs... they're like Salami. It might sound wierd but... I really want to make a sandwhich out of your legs right now.
Another thing she says also firmly cements it:
Foxy: Well, the beach has alot of people so I suppose the spa. Just a bunch of girls and stuff. (followed by this image◊)
Foxy: Danny is in fact a hot girl. I sure hope this battle goes well!
A later interview reveals that at least part of this was a combination of shitty English and laziness-only one of the many "Baro"s running around was supposed to be the creator. The rest were just named "Baro" because in that part of the world "Baro" is analagous to John in that it's obscenely common.
That One Boss: Max. Why? Because all his Pokémon have earthquake in the third gym! I repeat! IN THE THIRD GYM! He also had a Pokémon learn fissure.
The one with Fissure didn't have any non-ground-type moves, though, making it unable to damage flying-types.
Danny also counts. She uses dragon type Pokémon. Worse? IT'S A DOUBLE BATTLE! Worst of all? See below.
NIEVES. Again, painfully hard Gym, but she has two stupidly strong Pokémon; Freech and Bobeguin. Freech is Dragon-type when all her other Pokémon are Ice, and it has, of all things, Speed Boost, as its ability. And it knows Dragon Claw, which is stronger thanks to STAB. Bobeguin knows Blizzard, which can potentially one-shot anything under Level 30 (which, depending on how much you grind, could be your whole party) thanks to STAB, and it also has Surf to counter your Fire-types.
Maroon Gym is arguably worse. Nieves is also pretty hard, but her gym is Wallace/Juan's gym combined with cracked floors that lead to a trainer-less basement/upper floor note If you take ladders that go up or jump down holes, you get to the same place. with ladders that have no correlation to where they should lead to. That alone would make this on par with Greystone, but then there's also INVISIBLE TRAINERS THAT ATTACK YOU WHEN YOU TOUCH THE WATERFALLS.
The eighth gym has numerous floor tiles that will send you back where you started, which can get on many players' nerves if they don't know where to go. There is no indication for which tiles are safe or not. Thankfully, the Gym Leader is a Breather Boss.
Ugly Cute: The new Pokémon designs could be described as this.
Unfortunate Implications: The swirls in the desert that are supposed to represent quicksand, though they look like Swastikas.
