Top 10 Hardest Pokemon Bosses

The Top Ten
1 Red (HeartGold & SoulSilver) Red is a Pokémon Trainer from Pallet Town, Kanto. He is the first character to be playable in the Pokémon series and his initial appearance is set in the Generation I main games. He has since then made various appearances in Pokémon media, including the Generation III remakes of Red, Green, Blue,... read more

I had so many problems beating him first off his Pikachu is Level 88! It WILL Kill you if you don't have a ground type. His Snorlax is very strong but he is slow. His Lapras is Immune to Hail. His Charizard can be hard without Rock type attacks. His Venusaur can use Frenzy Plant and Kill you almost instantly without Fire. And last but not least Blastoise High defenses require you to use Special attacks like thunderbolt!

The main reason I have trouble with Red is because of his levels, and moves. His Venusaur is not a problem because I have a fire type starter. Charizard, and Pikachu are also no problem Since I always use my lugia and grass type, but the main problem is that his Lapras, Snorlax, and his Blastoise have the move blizzard and all my level 70s, and 80s are weak to ice. I've never beaten red to this day he should be number 1 darn it!

2 Cilan (Black and White) Cilan is one of the three Gym Leaders of Striaton City's Gym, known officially as the Striaton Gym, in Pokemon Black and White. In the anime, he is classified as an A-class Pokemon Connoisseur and traveled with Ash Ketchum in the Unova region. He first debuted in Triple Leaders, Team Threats!.

Anyone who is anyone hates the monkeys. So you probably didn't bother to level up your monkey, so you have almost no chance against any of the gym leaders. Plus, the Lillipup is annoying too. So have fun...

3 Brock (Yellow) Brock is a character from Pokemon and is created by game freak & Nintendo. He was the first gym leader in pewter city, and specializes in rock Pokemon ... read more

In Pokemon yellow I remember going with the starter, pikachu and being thrashed. Nidoran and mankey, the only Pokemon who could properly beat his wretched onix only learn the correct super effective moves at later levels. They are also rare to find.

4 Shadow Lugia (XD: Gale of Darkness)
5 Cynthia (Diamond and Pearl)

I mean, hard! The rematch... A level 72 Lucario, a level 72 Togekiss, a level 78 Garchomp? Also, she has a well-balanced team with generally good moves (Why does Garchomp have Giga Impact? )

Weavile can't even one shot Garchomp. If anyone can manage this without Weavile, Scizor/Mamoswine combo or Altaria, you forever have my respect.

I sighed in relief when I had FINALLY beat her after the fifth or sixth time. How can she NOT be at number 2 at least?

6 Mew (Snap) Mew is a Psychic-type Mythical Pokémon created by Nintendo's and Game Freak's Pokémon media franchise. Designed by Satoshi Tajiri, it was introduced in Pokémon Red and Blue. Mew is capable of learning every move in the games (except signature moves of certain Pokémon), and can shapeshift into other... read more

I though I beat the game until I had to catch this thing, I have that beaten the game in a year or 2!

7 Dialga (Mystery Dungeon 2) Dialga, known in Japan as the same name, is a Legendary Pokémon species in Nintendo and Game Freak's Pokémon franchise.

First of all he isn't the Final Boss, Darkrai is, and Darkrai is much stronger and has stronger minions.

The Mystery Dungeon series has some crazy strong bosses, and Dialga is one of them. He is far stronger of a challenge than any Champion or Red.

Aside from chakron, in mario RPG2, this guy is pretty much invincible, If you don't use sleep seeds and focus punches fast, I guarentee he'll cream you with his roar of time, Plus the ending, and when you recruit him its great to use roar of time and for darkrai's battle!

8 Ghetsis (Black and 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 actually did defeat him my first try, but just by the skin of my teeth. I had to constantly keep healing my pokemon over and again. I eventually did run out of full restores and revives and I had only pokemon left that was very low on health when I beat him. My heart was beating the whole time fighting him.

My first Pokemon game was Pokemon Black Version, and for me, I think this was the hardest Gen I have ever played (since Gen VI wasn't as hard as Gen V). I kept losing to Ghetsis so much that I actually had to leave N's Castle just to train my Pokemon more so I could finally beat Ghetsis!

9 Ultra Necrozma (Ultra Sun and Moon)

True, it's easy to bet if you know what you'll be fighting and make up a strategy, but if you're going in blindly or in a challenge run (like a nuzlocke for example) this thing is a dream wrecker.

This thing... kills my Pokemon Every! Single! Time! Boost to all of its stats, insane base stats, and a moveset of Photon Geyser, Dragon Pulse, Smart Strike, and Power Gem. Oh, and don't forget its ability, Neuroforce (Powers up moves that are super-effective.) This thing should have been #1.

Higher stats than Arceus, Totem aura, and excellent type coverage. How much more OP can you get?

10 Angeallen (Platinum)
The Contenders
11 Whitney (HeartGold & SoulSilver)

This fight is overrated. First of all, the game throws in two Rock types with high defense early in the game that are easy to get. Second of all, you can trade for a Machop in the Goldenrod Department Store. Thirdly, Heracross is able to be found in Azalea Town and its Brick Break will OHKO Miltank. Fourthly, Bayleef learns Reflect lowering the power of Miltank's physical moves. Fifth of all, why does nobly remember about genderless or female Pokemon? The Machop you get traded is female!

Come on, really guys? There are several ways to take out Whitney!
For a start, you all miss out good opportunities to get decent Rock types early on in the game, Golbat can stop Miltank from kicking your butt and Heracross will make even Miltank seem like child's play. You can also fight a good chunk of Trainers before even challenging her. So just don't, ok?

12 Lance (HeartGold & SoulSilver)

He has over powered pokemon and too many items! Even with my supply of over 100 full restores I still managed to never ever ever beat him so a can't put Kanto bosses on here. The only reason he's #4 is because I thought that other people could beat him more easily than the Top 3! In fact the only other one I flat out couldn't beat was #1 who can beat you way faster!

All I can say is, Lance is difficult.
For starters, his Pokemon are Lv45-50, with 3 Dragonite, which will destroy you if you don't have Ice type moves. Secondly, you need to level grind on Victory Road, where Pokemon are Lv35 AT MAXIMUM! I ended up getting my Hitmonchan to Lv46, and just kept destroying his whole team. Stealth Rock works on his whole team, especially Charizard. It's not fun, but still possible.

13 Steven Stone (Emerald)

His Metagross is a montrosity. Aggron is a novelty. He punishes you enough with Armaldo, stalls with Cradily and spikes you down with Skarmory. His Claydol's the only thing not dangerous.

Watch out for him at the end of the game, he has levels 72 to 78 and you can battle him immediately after beating the Elite Four and Champion!

Such a nightmare. Aggron can beat my level 98 deoxys in 1 hit in defense form.
Metagross beat my level 100 mega rayquaza.

If it hadn't been for my Blaziken dodging Metagross's Hyper Beam, I would've been destroyed.

14 Primal Dialga (Mystery Dungeon 2)

It will let you approach it unlike normal Dialga but it can easily K.O. You or your partner in 2 hits and has about 670-1000 HP!

15 Cynthia (Black and White)

Her garchomp is the most terrifying pokemon ever... even for an experienced player, if you don't have a strong ice or dragon type you are screwed. And that's without having to worry about the other pokemon...

I haven't played this, but from what I've heard, Cynthia is a beast.

THIS is what you think the hardest is? Just use whoever you used to beat Ghetis with!

16 Totem Lurantis (Sun and Moon)

This pokemon is way too broken. It has Solar Blade along with Power Herb from the start. It can immediately attack with basically a physical Solarbeam once it uses it. Not only that it has Synthesis to restore its health. Its allies also causes pain in the neck. Trumbeak with Rock Blast kills fire types and flying types, which you definitely need in order to beat. Castform uses Sunny Day, which allows 2/3 of its health to be restore and immediately charges its Solar Blade... This Pokemon should never be underestimated.

17 Evice (Colosseum)

The level jump between your own pokemon and his is incredible. If you were lazy you had like level 45-50 pokemons (because you caught opposing pokemon such as level 50 metagross), and if you took the time to grind up in Mt battle you should have level 50-52 pokemons. The thing is that Evice has level 60 pokemon with way more elaborated strategies than classical bosses: dd salamence (egg moove), baton pass scizor, skill swap slowking in order to remove slacking's main issue: truant.
The difference that makes Evice harder than red is that it's a double battle, and you can't beat with multiples X attack in order to fully sweep his team with one pokemon (easily doable with red, even if your pokes are level 50). Double intimidate and the lack of reliable ice beam user (except suicune there is not viable water/ice type in the game that you can catch) puts a lot of pressure and forces you to focus him in order to prevent him from setting up.

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

Her Mother Beast form is overpowered as hell!

Strong and varied team. Mamaged to knock out even some of my overleveled mons

19 Dusknoir (Mystery Dungeon 2)

3 against 8 gives the enemy a 5 man upper hand! The sableye have about 93 Hp but dusknoir may well have about 800 Hp! Dusknoir can deliver about 70 damage per blow and Sableye can can do about 30 do the math and that's about 93 damage per team member, ouch! However these are fron the math is best their strongest attacks and if they all attack so don't get too worried!

This is like Luxray and the Luxio times a bazillion. Your only strategy is to confuse Dusknoir. For every 1 battle I have with Primal Dialga, I have 10 battles with these guys.

20 Greevil (XD: Gale of Darkness)

Speedster did a countdown on the hardest Pokemon battles and this was number 1, and let's just say he made a pretty good point. I think you should check it out and he also talks about why Whitney isn't as hard as we all say. I'm voting for this until it's number one. What are you guys even talking about for the number one choice, and in another list, Speedster also explains why the battle with Red isn't as great as we all think it is.

Fighting him whilst having to catch ALL SIX of his team is a nightmare. All the Pokemon are strong. They are Rhydon, Exeggutor, Tauros, MOLTRES, ARTICUNO AND ZAPDOS. All of them also have high catch rates, especially the birds, so you will need LOTS of Pokeballs. Also, if you score a critical hit, you may accidentally KO one.

For those who are unfamiliar with, the goal of the game is to catch all the Pokemon your opponent has that are Shadow Pokemon (in Greevil's case, all 6). These Pokemon also have special attacks that deal super-effective damage to all non-Shadow Pokemon - they will hit any Pokemon you use hard with the exception of other Shadow Pokemon. I strongly recommend not purifying all your Shadow Pokemon before this match else your entire team will be KOed quickly (especially Salamence - could have not won without it! )

And if you want to use the Master Ball on them, that means no Master Ball for Shadow Lugia. And any damage you take against Lugia gets carried to the fight against Greevil, so that's not a good idea.

I definitely don't recommend catching all 6 of his Pokemon at once. Whilst doable, you will need LOTs of tries - I did it, but it took me far more attempts than it did with any other Pokemon trainer by far.

21 Lenora (Black and White)

Wow, I figured out how to beat her a long time ago.
Use your starter otherwise, but if you started with Snivy, get a Fighting type from Pinwheel Forest. Give your main killer a Chesto Berry and when she switches in to Retaliate, switch to your HM Slave. I beat her on the first try, even as a Pokémon newbie many years back!

After finally beating the ferocious beast known as Herdier, you have to face her Watchdog. It usually starts the battle with Retaliate, which pwns your pokes most of the time. And then it starts spamming Hypnosis and Crunch.

22 Drapion (Ranger 2)

I had to restart my game in order to beat him because I chose Crogunk as my partner. I went back with a different partner and beat him, but was still super hard. This boss is the hardest pokemon boss I've ever faced myself in a game for me!

If you chose crogunk as your partner, you are screwed. You can't get off the ship ship to change your partner, so you have to restart the game :( took me a long time, but while, but I finally got it

23 N (Black and White)
24 Morimoto (Black and White)
25 Pokemon Wielder Volo (Legends Arceus)
