Out of the more than 20 seasons in the Pokémon anime franchise, there are some that fans should definitely see, and others they should avoid.
Although Huntail may not be the strongest Pokémon to exist in the franchise, it still poses a danger to other creatures it comes across. It uses its fish-shaped tail tolure in unsuspecting preybefore finally attacking and swallowing them whole. Even if its prey were to attempt hiding, Huntail’s exceptional eyesight could still spot them in the dark waters, making them rather crafty and efficient hunters.

9Seviper
A Snake With A Poisonous & Sharp Tail
Seviper is a very recognizable snake Pokémon from Generation 3. It is best known forits long-standing rivalrywith Zangoose. According to the Pokédex, these feuds have often left many Sevipers covered in various scars, proof of just how unrelenting a fighter Seviper can be.

To craft the Poison Tail or Poison Jab TM recipes in Pokémon Scarlet and Violet, Trainers must know how to find and catch the Fang Snake Seviper.
Not only is its pointed tail poisonous, but it’s also described as being sword-like due to Seviper sharpening it on large rocks. Seviper is also known towrap its body around its preyin order to trap them before poisoning them with its tail or fangs, so it’s best to avoid getting caught by one. With how dangerous this venomous snake is, it’s no wonder thatJesse from Team Rocketowned one while in Sinnoh.

8Arbok
Paralyzing & Poisoning Foes Before Attacking
Another threatening snake Pokémon, Arbok, is similar to Seviper, though it has a few noticeable differences that make it more dangerous. It also haslong, venomous fangsthat can prove deadly to humans and Pokémon, so anyone who encounters one in the wild should steer clear.
When hunting, Arbok is able toimmobilize its prey using the patterns on its bodybefore eventually wrapping itself around it to crush it with its immense strength. The Pokédex explains that said grip is impossible to escape from and is so strong that it can even crush an oil drum. Considering the fact that Arbok is known to be unrelenting when chasing prey, it is unlikely that one would be able to escape once in Arbok’s sights.

7Onix
A Giant Serpent Made Of Rocks
Onix is already incredibly imposing as a giant snake composed ofnearly twenty-eight feet of giant boulders. It is known for being a particularly aggressive Pokémon, which isn’t good for anyone traveling through the mountains. With powerful moves like rock throw and stone edge at its disposal, it can easily hurt or crush anyone who happens to anger it or possibly trample it with its massive body.
Onix are also known for living deep underground, where they can dig tunnels atspeeds that can reach up to fifty miles per hourdespite the massive size of their bodies. Such actions have been known to cause massive tremors, creating trouble for hikers and other travelers. There is always a risk that humans could end up falling into whatever holes Onix makes in the ground, which can end up being incredibly deep and dangerous.
6Sandaconda
A Docile Snake That Attacks With Sand
At first glance, Sandaconda might not seem all that dangerous, but it proves that looks can be quite deceiving. Its large pouch canstore up to 200 pounds of sand, which it can blast out with enough force to blast away a dump truck. Sandaconda can even combine this sand with its own saliva to create incredibly sharp pieces of gravel that can easily make deep cuts in one’s flesh.
Sandaconda’s gigantimax formmakes this Pokémon even more dangerous to be around, as it is able to become even more powerful and destructive. The amount of sand that this form holds jumps up to one million tons, and it is able to create a massive sandstorm that can createenough force to demolish an entire skyscraper. This is all proof that as docile as Sandaconda might appear at first glance, it is wise to avoid antagonizing it at all costs.
5Gyarados
A Sea Serpent That Can Level Cities
Magikarp starts out as a rather docile and rather harmless Pokémon, but that all changes once it evolves into Gyarados. With many powerful moves such asHydro Pump, Thrash, and Hyper Beam, it is quite obvious just how much of a threat this Pokémon can be when out in the wild. Combined with the fact that it has the ability to mega-evolve, it is no wonder why many powerful trainers seek it out to utilize its strength.

Pokémon is filled with incredibly charming creatures, but some scary much more visual appeal than others. There’s a reason some Pokémon are so iconic!
The Pokédex describes this massive sea serpent as beingable to destroy entire cities in a fit of rageif angered enough. This means that any sailors that come across a Gyarados during their travels stand no chance against its unrelenting fury. As incredible as this Pokémon is, encountering one in the wild is almost certain to lead to disaster, especially for anyone caught unprepared to handle Gyarados' immense power.
4Zygarde
Immensely Powerful Despite Being Incomplete
Zygarde is a legendary Pokémonwith numerous different forms, and although its serpent form is only at half of its full power, it is still immensely dangerous to encounter.

There are a wide variety of attacks that Zygarde can utilize in order to deal with its opponents. Its signature move, Thousand Arrows, can hurt opponents even when hiding underground, while other attacks like Outrage utilize the immense strength of its Dragon typing. The anime even shows this version of Zygarde being capable ofsummoning and manipulating massive rootsto attack, meaning that it can turn the entire forest against those who seek to harm it.
3Rayquaza
An Incredibly Powerful & Heroic Sky Serpent
This ancient legendary Pokémon from Generation 3 is best known for being able to quell the fighting between Kyogre and Groudon, and it’s clear to see why it’s so capable of doing so. It is immensely fast, being able to fly at such high speeds that itcan evendestroymeteors. It can also summon powerful cyclones to overwhelm its opponents, utilizing the weather to its advantage.
Rayquaza’sability to mega evolveonly serves to heighten its own speed and strength even further, as well as undo the primal power of both Kyogre and Groudon. With all this power at its disposal, it’s good that this legendary Pokémon has such a heroic nature.
2Giratina
A Serpent-Like Dragon From Another Dimension
As the ruler of the Distortion World, Giratina is already an immensely dangerous and powerful legendary Pokémon, and its origin form makes it all the more terrifying. Giratina’s origin form allows it tounleash its true strength, which is seen during the fight against Volo at the end of Pokémon Legends Arceus. Its serpent-like appearance truly makes it resemble a dangerous being from another world, thereby adding to its mystery.
With its true power unleashed, Giratina hasnumerous terrifying attacks at its disposal. It can disappear into thin air, attack with Shadow Force, and strike the opponent with other powerful moves like Shadow Claw, Aura Sphere, and Earth Power. The fight against Volo and the various moves prove why Giratina should be avoided should anyone be unfortunate enough to come across it unprepared.
1Eternatus
Capable Of Causing The Apocalypse
Although this legendary Pokémon’s power is responsible for providing the people of the Galar region with the ability to Dynamax their monsters, it is still one that many would want to avoid out in the wild. Eternatus is so powerful that it can bring about an apocalyptic-level event known as The Darkest Day, where a dark storm covers the region, and numerous Dynamaxed and Gigantimaxed Pokémon end up going berserk. As cool as Eternatus may appear, it is, without a doubt, the most dangerous snake-like creature in the entirePokémonfranchise.
