Hardest challenge in BW.

[AuraChannelerChris]

Elesa's gym is only hard if you don't have the following
rock types
ground types
ice types

Rock types - Roggenrola/Boldor(?) doesn't have good Rock type attacks unless you sacrifice training for all your Pokemon to level it.

Ground types - Sandile/Krokorok gets screwed due to the two Emolgas using Flying type attacks. Worse yet, those two squirrels from hell are deadly fast. Drilbur is a good option but she also employs Flame Charge.

Ice types - There's not a single Ice type before Elesa unless you resort to trading. Moreover, her Zebstrika knows Flame Charge sooooooooo...

Post-Elite 4 gave me quite an challenge. I had to use a lot of Revives to get through it...

 

[DrasticPhase]

My hardest challenge was burgh when i was usimg snivy and of course lenora

 

[XXD17]

The battle facility/ subway is my hardest challenge...freaking pokemon with broken stats and having hax to their advantage...even my fully EV trained pokes barely stand a chance...

 

[Cerex]

The battle subway is annoying because of how bad it's all stacked against the player, but that's to expected. The hardest challenge for me were the trainers post the E4, they had such a ridiculous spike in levels in comparison to the Elite Four that my entire team blacked out several times.

I could Lenora being difficult if you didn't have Pignite but one of the other starters.

 

[arceus7]

Lenora isnt hard at all lol , ever heard of Sawk with Sturdy?

Elesa is hard because their isnt a single good counter pokemon since her zebstrika with flame charge rogen doesnt have a reliable ground type attack yet ( mine had smack down and I also had a krookodile so I just used smack down switch to sandile use sand tomb and rocktomb buhbuy you elmos!

I had a Drilbur and it was hard. Rock Tomb didn't do much, the Emolgas were immune to Dig, but at least they were limited to Aerial Ace, Pursuit, and Quick Attack.

 

[GoldNinja]

The time when you enter the Elite Four for the first time, that was hard xD Almost threw my DS on the wall 'cus my pokemon kept fainting!

I blame my inexperience though, it was my first time against them and I didn't know what to expect - turned out my pokemon were underleveled xD Naturally now I can go through the E4 no sweat

 

[@MiGo]

Not much in black and white was extremely difficult for me, probably just Lenora and her stinkin' retaliate move lol. That or battling caitlin after the main game.

 

[mew0099]

N's Sigilyph in Nimbasa City defeated me numerous times .
Lenora was difficult but I made it through [ urgh , retaliate ! ] .
But the hardest for me was the Elite Four - I almost didn't make it through ! I only had one level 50 on me , no revives , and no legendaries .

 

[Drdj11]

Ok what the **** I was in the battle facitly and I was about to win but then, Some dude came in and he had a frickin legendarys I'm not joking I am for real!

 

[Typhoon_HG]

Elesa was my only real challenge. I had to train up my Archen to Lv. 30 before I even had a chance against her Emolgas. Other than Grimsley's Bisharp, the E4 was fairly easy and I took out Ghetsis' Hydreigon pretty easily. Also, even though I was pretty underlevelled, Unova's eastern side wasn't to hard (although the first battle took me by surprise).

Edit: N's Sigilyph in Nimbasa was pretty hard too.

 

[lucario beast]

elesa and her emolgas

 

[watermelon_1234]

Ghetsis's Hydreigon.
I was only able to take it down by stalling it with Jellicent's Will-O-Wisp and Recover. >.> (Well, at least it boosted my appreciation for Jellicent.)

 

[Mr. Reloaded]

Elite Four what a pain in the ***

you said it for sure

 

[Paradoxe]

N's Sigilyph in Nimbasa City defeated me numerous times .

This. I didn't have anything that was effective against it, so I got wiped out by it numerous times.

 

[Drdj11]

Yeah alright let's get some more posts in tell your friends about it!

 

[Flydreigon]

The only thing that was remotely hard for me was Elesa and her two Emolga. I had super effective on them at the time. I expected Ghetsis' Hydreigon to be really hard for me, but I think I took it out with a couple HJK from my Scrafty.

 

[General Nonsense]

The battle subway is the hardest challenge. I still haven't gotten more than 24 wins in any of the super lines ;_;

Also the sudden level increase of the NPC's pokemon post E4. I was shocked when the opponent's pokemon were almost 20 levels higher than mine.

 

[fuyu-seetaa]

The first was Elesa. I had Panpour (weak against Electrics), Tranquill (weak against Electrics), and my Herdier and, um, I'm not sure if it was a Patrat still or a Watchog. Anyway, I also had Servine. It's kinda obvious why she was so hard, and some other trainers in her gym (Acrobatics takes out Servine, Double Team is... annoying, and Volt Switch...).

Later it was the Elite Four (when I first challenged them). Caitlyn and the ghost-girl were the hardest with Reuniclus (Focus Blast) and Chandelure (Fire Blast). Not to mention Ghetis and his Hydreigon AND Eelektross. How does it know Flamethrower?! It's an eel!
