Top 10 Hardest Pokemon Battles in Pokemon Games

The Top Ten

1 Ghetsis (Pokemon Black/White) Ghetsis (Pokemon Black/White) Ghetsis Harmonia, or simply Ghetsis, is the main antagonist in Pokemon Black and White and the direct sequels, as well as the adoptive father of N, Concordia, and Athea.

I lost to him multiple times. I had to keep on training my Pokemon until I could come back to N's Castle to finally finish him off. - ModernSpongeBobSucks

Level 54 Hydreigon, enough said.

6 vs 12 pokemon (can't restore your team after N battle), high level team and a unfair hydreigon...

Hydreigon. Please have mercy on me lolol. - HeavyDonkeyKong

2 Cynthia (Pokemon DPPt)

I agree, I had many tries to beat her and I failed. Luckily, I noticed that I defeated her Garchomp with TM that I still had and I used it for Empoleon, and that was "Ice Beam". I guess water types DO manage to let you win and progress the game.

One word Garchomp

If only we had fairy types then

This bitch was sooo high on cocaine I had to try too many times before I beat her. My team was really strong (Infernape, Gyarados, Tangrowth, Umbreon, Jolteon and Giratina), yet she managed to beat me 6 times in a row. I grinded to Level 100 before my 7th attempt and that's when I beat her.

3 Greevil (Pokemon XD: Gale of Darkness)

Greevil is without a doubt, the hardest battle in Pokemon history. His entire team are shadow Pokemon. Good luck cause you're going to need it!

This guy deserves to be number 1! I really like this battle but it is without a doubt, the hardest battle in all of Pokemon!

He is so very jerk and jerk boss when he is the hard boss easily!

Good luck catching 3 legendary pokemon in one go.

4 Professor Kukui (Pokemon Sun and Moon) Professor Kukui (Pokemon Sun and Moon) Professor Kukui is a fictional character introduced in Pokémon Sun and Moon. He is a Pokémon Professor from the Alola region, as well as the founder of Alola's Pokémon League.

Honestly I had more trouble with Olivia (Elite Four Version) than Kukui, I think he is worthy of being the "Champion Boss" but honestly compared to all other champs maybe Iris is only weaker than her

Overall, I wouldn't say the battle against him is harder than Cynthia. For the most part. Aside from that one giant blob of green fat that you know you're gonna have so much fun taking down... - Zach808

It was hard, but I did the mother of all pokemon challenges, beating the game without trading!

He's to easy.he only took down two of my Pokemon!

5 Evice (Pokemon Colosseum)
6 Anabel (Pokemon Emerald and Pokemon Sun and Moon)

Build a team just for this, or spam healing items as hell. And oh yeah, save before you fight her.

7 Ultra Necrozma (Pokémon Ultra Sun and Ultra Moon)

Ultra Necrozma will outlevel, outspeed, outattack and generrally all of its stats due to it's aura at the beginning of the battle. I know, you're probably thinking "Mimikyu will take care of it, with disguise and fairy and Ghost type moves, what could go wrong? " Well, It knows Smart Strike, which Mimikyu is 2x weak to. Gg. And with Photon Geyser, will probably one hit ko most of your mons. If you are using Incineroar, it's Power Gem for you. Take a look:

8 Lusamine (Pokemon Sun and Moon) Lusamine (Pokemon Sun and Moon) Lusamine is a fictional character introduced in Pokémon Sun and Moon. She is the head of the Aether Foundation.

God, her Mother Beast form is overpowered! I wasn't able to take down that Clefable until that thing used Metronome and it got the move Self-Destruct to use on itself! But it was kind of funny when that Self-Destruct missed my Alolan Raichu that I was battling with due to the bonds that I have had with it as a Trainer. - ModernSpongeBobSucks

Yes, Lusamine is the hardest battle!

This is an awesome boss fight, perfect mix of hard and fun. The Clefable was pretty annoying but seriously, I wish I could refight her.

That Clefable though... I get mad just thinking about it.

I'm gonna use a Clefable that has the same moveset as Lusamine's against my brother just to piss him off. He'll hate me for it but it'll be worth it

Also, Cosmic Power is officially my least favorite move. And did I mention my luck is bad? So when it used Metronome, you can imagine how well I took it. - Absolite

9 Eldes (Pokemon XD: Gale of Darkness)
10 Trainer Red (Pokemon GSC/HGSS/Sun and Moon)

I was in the lower seventies but still managed. His sets were terrible. I would have curbstonped hi. Had it not been for the level difference to be honest. I only barely won though because of the level difference though in my opinion. - HeavyDonkeyKong

The level curve in G/S/C just doesn't prepare you for Red. Everything in Kanto is badly underleveled, but Red is in the high 70s and low 80s. The first time I reached him in Crystal, my team was in the high 40s. You can guess how well that battle went. - Zach808

The Contenders

11 Ardos (Pokemon XD: Gale of Darkness)
12 Hapu (Pokemon Sun and Moon)

She was it took me 14 times to defeat her because of her hard flygon super hard mudsale

13 Lucian (Pokemon DDPt)

Hardest E4 member to ever exist in my opinion. Period in my opinion. - HeavyDonkeyKong

14 Clair (Pokemon GSC and HGSS) Clair (Pokemon GSC and HGSS)

You want to hear my hatred for this battle in one single word? "Kingdra". - HeavyDonkeyKong

Harder than Whitney!

15 Totem Marowak (Pokemon Ultra Sun and Ultra Moon)

I swear to God, they made this fight as hard as it is as a subtle reference or something

16 Jaun (Pokemon Emerald)
17 Steven (Pokemon RSE)

I did find difficulty with him in ORAS to be honest. But in emerald he was insanely hard though lolol. Never played the original Ruby and sapphire though lolol. - HeavyDonkeyKong

18 Totem Mimikyu (Pokemon Sun and Moon)

Aside from Mimikyu being hard to take down, I find it hilarious that people used their Z-move on the first turn to try and one shot it just to realize that Mimikyu has the disguise ability. - Rue

Sadly, I was dumb enough to use my Z move on the first turn, still beat it first try though. Seriously? How is this even hard?

19 Kecleon (Pokemon Mystery Dungeon) Kecleon (Pokemon Mystery Dungeon)

This thing -- is almost invincible to any of my Pokemon. Just screw Kecleon. Can't they just make so that if you have no money, and try to take an item from Kecleon shops, he gives to you for free? Then again, this thing is simply one word: UNFAIR!

Pokemon's version of the fight with Sans the Skeleton. Get Dunked On! - SocialMediaStinks

20 Lenora (Pokemon Black and White)

Herdier is NAD. Watchog is worse. - HeavyDonkeyKong

21 Norman (Pokemon Emerald)

That Slaking. Oh my gosh that Slaking. - HeavyDonkeyKong

22 Brawly (Pokemon Emerald)

Brawly was so hard in Pokemon Emerald that I made sure I was 100% prepared to fight him in ORAS. Turns out they nerved him to all hell. It felt...underwhelming. - Rue

23 Elesa (Pokemon Black and White) Elesa (Pokemon Black and White)

EFF those emolgas in my opinion lolol. - HeavyDonkeyKong

24 Champion Blue (Pokemon RBY)
25 Lance (Pokemon GSC and HGSS)

Lance is only hard if you are new to Pokemon and are not sure what you are doing. Which is a lot of kids back in gen 2 where it was still new. With experience, his difficulty is lacking. - Rue

Nah. I brought ice beam and thunderbolt. Without it he would likt be very bard though lolol. - HeavyDonkeyKong

26 Nanu (Pokemon Sun and Moon)
27 Sabrina (Pokemon RBY)
28 Lt. Surge (Pokemon Fire Red and Leaf Green) Lt. Surge (Pokemon Fire Red and Leaf Green) Lt.

She was also the female character in Ruby, Sapphire, Emerald, Omega Ruby, and Alpha Sapphire. May (anime) debuted in the 275th episode, "Get the Show on the Road!"

Ugh, I had to lose to her, even after trying to defeat her, I tried! Not counting the 3DS remake (because she's easier to beat, which I LIKE! ). I hate her a LOT because of several reasons! Oh well.

35 Benga (Black2/white2)

Hard as always

36 Juan (Pokemon Emerald)
