Poison-types are some of the most popular types of Pokémon in the game, appearing on nearly every Elite Four and Champion team. If your team is like most others, it’s likely that Poison-types will be a part of it. ..

  1. Gyarados - A powerhouse dragon-type that can take on most opponents with ease, Gyarados is a must-have in any Gen IV game.
  2. Salamence - A massive dragon-type that can take down even the strongest opponents, Salamence is a must-have in any Gen IV game.
  3. Machamp - A massive and powerful human-type that can take on most opponents with ease, Machamp is a must-have in any Gen IV game.

3. Gengar

Gengar is the best Ghost-type in this game, but it doesn’t make it the best Poison-type.

Gengar is a great Pokémon to have on your team, but it doesn’t excel in the Poison department.

Gengar is a Ghost-type Pokémon that is best suited for using its Ghost-type moves. It has few Poison-type moves, so it will need to rely on those to take down its opponents. ..

It can still learn the best Poison-type status move in the game though, so we can start by teaching it Toxic through the TM found in the Battle Frontier Shop.

Shadow Ball is a powerful STAB move that can be learned by Gengar or Haunter at level 33.

Gengar’s main weakness is that it’s weak to Dark-type attacks. The best way to counter this is with a move called Focus Blast, which can be found at the Goldenrod Department Store. ..

Since Gengar has the ability to levitate, it won’t have to worry about its Ground-type weakness, so we can use the final move slot to cover its low defenses. ..

Since Gengar doesn’t have any moves that will directly buff its defenses, we’ll instead make do with an indirect buff.

Will-o-wisp is a Fire-type move that is guaranteed to burn the opponent if it hits, bringing along with it the attack drop that comes with being burned.

This will effectively double the amount of hits Gengar can take from a physical attacking opponent. You’ll find Will-o-wisp (TM61) in the Battle Frontier Shop.

To catch a Gastly in Sprout Tower, you’ll need to evolve it into Haunter at 25. Once you’ve done that, trade it to another Gen 4 game and back again to get your Gengar.

2. Roserade

Roserade, a Grass-type Pokémon, does not learn any moves by leveling up. ..

Building a move set for Roselia is important, as evolving it before you’re finished can lead to unintended consequences. ..

Roserade is a Grass type Pokémon that can learn a variety of powerful moves, making it an excellent choice for any trainer. To build Roserade, start by choosing a strong move to base its abilities off of. For example, if you want your Roserade to be able to use Sunny Day, choose a move like Solar Beam that can also hit Ghost types. After you’ve chosen your move, make sure to give Roserade some other helpful abilities so it can stand out on the battlefield. For example, if you want your Roserade to be able to use Morning Sun, give it the ability Natural Cure so it can heal itself in battle. Finally, choose a set of stats that will help your Roserade perform its best in battle. For example, if you want your Roserade to have high Defense and Special Defense stats, choose those stats as your Pokémon’s main focuses when leveling up. ..

We’ll be using Roserade’s huge special attack stat to power up its Grass and Poison-type moves, as well as teaching it some utility to back up its low health stat. ..

Toxic is a powerful move that is learned naturally at level 37 in the Battle Frontier. It is a strong attack that can deal a lot of damage to your opponent. ..

We’ll be giving Roserade two Grass-type moves, which will act as its main damage-dealing moves.

At level 25, Roselia will learn Giga Drain, which will return half of the damage it deals back to the user, healing Roserade’s otherwise frail HP bar. ..

At level 40, we’ll teach Roselia Petal Dance, a Grass-type cousin to Outrage which deals special damage for two to three turns before confusing Roselia. ..

The Petal Dance can go through both Misty and Brock’s Gym Teams with one use. Be sure not to evolve Roselia before level 40.

For our final move, we can either choose to spend a turn curing our team of status effects with Aromatherapy, or paralyze the opponent with Stun Spore.

Both moves are learned by leveling up, at level 43 and 10 respectively.

I build Roserade with Aromatherapy because it paralyzes a Pokémon with Stun Spore, negating the effects of Toxic.

To catch Sinnoh Pokémon, tune into the Pokémon March radio station on your PokeGear on Thursdays for news about Johto and Kanto Pokémon appearing across the region. ..

Pokémon that may appear in the grass on Thursday are Budew, Vaporeon, Jolteon, Flareon, Machamp, Golem, Dragonite, and Gyarados. Be sure to check the radio each time you come out of battle until you eventually encounter a Budew.

Budew can be trained to reach a high happiness level in a short amount of time, and then level it up in the daytime to get a Roselia.

After you have obtained your final levelup move with Roselia, get a Shiny Stone by winning the National Park Bug Catching Contest. Use it on Roselia to evolve it into Roserade.

1. Crobat

First, Crobat is the most versatile of the three. He can both fly and swim, making him a versatile attacker or defender. Additionally, he has a powerful attack that can take down even the strongest Pokémon. Finally, Crobat is also one of the most intelligent Pokémon in the game, being able to understand complex commands and strategies easily.

Crobat is a versatile Pokémon that can be used on just about any team. ..

Regardless of what starter you picked, you can still make room for a Crobat, even if only to outpace and confuse just about every Pokémon in the game. ..

Confuse Ray is a powerful attack that Crobat uses to confuse opponents.

Every Crobat line member learns Confuse Ray naturally at level 21.

Poison infliction will be using Toxic, which was learned from the Battle Frontier Shop. ..

Then we’ll back this up with some offensive Poison-type STAB with Cross Poison, which can be taught by the move reminder in Blackthorn City for a cost of a Heart Scale.

Option 1: The user can use their STAB attack to hit multiple targets at once, dealing damage to each one. Option 2: The user can use their STAB attack to hit one target and then run away, dealing damage to that target as they run.

Aerial Ace is the best move for damaging enemies, while Fly is a decent option that’s nearly essential for your journey through the overworld. ..

After beating Cianwood City Gym, you can find Aerial Ace (TM40) and Fly (HM) in Mt. Mortar.

To catch a Zubat, you can raise it to level 22 and evolve it into Golbat. Then, raise Golbat’s happiness until it evolves into Crobat.
