Onyx is a Pokemon that belongs to the mixed type of monsters: among its abilities are the power of stones, and the ability to strike underground. He gained fame due to the fact that he is trained by one of the main characters of the anime - Brock, a friend of Ashe.
Onyx - Pokemon Snake
Being one of Brock's monsters, this stone inhabitant of the caves at first glance seems huge and invincible. Indeed, the external data is amazing: it consists of huge boulders of irregular shape, from light to dark gray, which decrease in size in the direction of the tail. According to the animated film, Onyx is a Pokemon that can reach 10 m in height and weigh more than 200 kg. With such parameters, it is not difficult for a monster to dig a hole in the ground, based only on its power characteristics. Subsequently, other representatives of the earthen type settled in the holes dug by him - Pokemon-pests of Digletta.
In food, this monster is unpretentious: Onyx is a Pokémon eating stones, giving it strength and making it already impenetrable armor. But with all its grandeur, stone-type Pokémon are weak before representatives of the water element, and Onyx is no exception.
What else is Brock's stone serpent famous for?
Onyx is referred to as the first generation Pokemon, and it was originally distinguished by the fact that, like Pikachu, it did not have evolution. Subsequently, after he uses the Metal Cylinder, he can turn into his perfect form - Stilix, which has a greater destructive power.

Pokemon Onyx, the evolution of which in the natural environment is impossible, was recognized as one of the 30 most popular Pokemon in the game Pokemon GO. But the developers of the game, Nintendo, do not believe that the monster is able to compete with starting Pokemon, and even more so with Pikachu. The reason for this they call the "limitation" of the monster - despite its size, it does not differ in either charisma or the desire to become the most powerful and developed, does not get along with other Pokemon. Compared to other stone monsters, he also loses: the Golem (which looks like a turtle with a shell made of solid boulders) is much more powerful than him, although much smaller in size, and Raibourne has the ability to destroy diamonds and learn how to attack water (Onyx and water are incompatible) .
Is it worth "pumping" Onyx?
Those who were lucky enough to trap a stone snake in a pokeball trap initially note its relatively good power characteristics: speed, ability to quickly move away from the enemy, endurance and a powerful blow. But it is advisable to engage in its development only if the coach is not going to use it against water Pokemon - their attacks, even in the initial forms of monsters, will have a double destructive effect on Onyx. Experienced trainers in Pokemon GO do not recommend the use of pollen, which “pumps” the Pokemon, improving its power characteristics and endurance, to Brock's monster and are advised to pay attention to the legendary Aerodactyl or Golem.
