Top 10 Hardest Pokemon Battles in Pokemon Games

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.

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

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.

GODDAMNIT GARCHOMP SCORING FOUR DRAGON RUSH FLINCHES IN A ROW TAKKNG OUT HALF OF MY WHOLE ENTIRE TEAM WHY GAMEFREAK WHY. - HeavyDonkeyKong

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

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

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:

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

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

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

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

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?

Herdier is NAD. Watchog is worse. - HeavyDonkeyKong

That Slaking. Oh my gosh that Slaking. - HeavyDonkeyKong

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

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

Hard as always

His Kingdra is even worse than Clair's!
