Pokémon Go

Legends and Mysteries
Commonly in the “Pokémon Leggendari” category are also included Mysterious Pokémon, a different type of rare Pokémon whose distinction has officially started since the 5th Generation.
The difference between these two categories is easy to explain in a nutshell: both categories include particularly powerful Pokémon, with the difference that the mostric monsters belonging to the first category are easier to find than the second. The mysteries can only be recovered after official events and distributions, or with the help of additional spin-off games with one exception to this rule: Deoxys, normally captured by Rubino Omega’s post-game and Zaffiro Alpha.
There are currently 802 different Pokémon species known: of these, only 47 are Legendary Pokémon and 18 are Mysterious. Generated by Generation, this is the complete list of Pokémon belonging to both categories, sorted by growing Pokédex number:

1st Generation: Articuno, Zapdos, Moltres, Mewtwo
2nd Generation: Raikou, Entei, Suicune, Lugia, Ho-Oh
3rd Generation: Regirock, Regge, Registeel, Latias, Latios, Kyogre, Groudon, Rayquaza.
4th Generation: Uxie, Mesprit, Azelf, Dialga, Palkia, Heatran, Regigigas, Giratina, Cresselia
5th Generation: Cobalion, Terrakion, Virice, Tornadus, Thundurus, Reshiram, Zekrom, Landorus, Kyurem
6th Generation: Xerneas, Yveltal, Zygarde
7th Generation: Tapu Koko, Tapu Lele, Tapu Bulu, Tapu Fini, Cosmog, Cosmoem, Solgaleo, Lunala, Necrozma
1st Generation: Mew
2nd Generation: Celebi
3rd Generation: Jirachi, Deoxys
4th Generation: Phione, Manaphy, Darkrai, Shaymin, Arceus
5th Generation: Victims, Keldeo, Trunk, Genesect
6th Generation: Diancie, Hoopa, Volcanion
7th Generation: Magearna, Marshadow

As we can see, the generations in which they were introduced were the fourth and fifth generation, corresponding to games released for Nintendo DS (the period ranging from Diamante and Pearl to Bianca 2 and Black 2).

They usually have some standard features to make their distinction more straightforward: sex is unknown, they can only be caught once per game, can not evolve, they do not slip from eggs or can pair. However, there are some exceptions:we can know the sex of 7 legendaries (Latios, Latias, Heatran, Cresselia, Tornadus, Thundurus and Landorus), Cosmog can evolve into Cosmoem, which in turn can evolve in Solgaleo or Lunala, depending on the game version chosen, and Manaphy can produce eggs, which will unlock to give birth to Phione.
The latter also has special exceptions (it can be hatched from eggs and in excess of 1), and as a result its status is often questioned, despite the fairly clear position of the developers who officially included it in this category

Looking for a challenge
If you are anyway part of those who want something more challenging, a challenge that truly demonstrates your strength to the whole world, then you may want to go back and take a look at Pokémon Go. We have already talked about some previous articles about the will to Niantic to give new lymph to the famous smartphone game thanks to the latest updates, and after one year of the official release of the app it’s finally time to fight Legendary Pokemon in the form of Raid Battles.
The arrival of these challenges further contributed to the extent to which we were able to say far more than the latest developments made so far, to bring back several old players to the game because they are drawn to the idea of ​​having one of these celebrated and powerful Pokémon, summer time where people tend to be more free from commitments. 
The legendary currently programmed for capture are Lugia, Articuno, Zapdos and Moltres, with the peculiarity that they will not be available forever: Niantic has indicated precise dates and times where it will be possible to capture powerful first-generation birds, while Lugia was not currently given a deadline.
Articuno himself has already disappeared from the radar since his deadline was set at 30 July, so now Moltres is scheduled to be available until 6 August, then he will be in Zapdos from 7 August to 13 of the same month. However, we know that the other legendary First and Second Generation are present in the game, so we can certainly expect some themed events in the near future to capture them.
And if you are going to face this challenge, be careful because their capture rate is incredibly low with only 2% chance of being able to get yours; So be sure to have many Gold Baccalampons available to increase your chances of success. Surely their integration within this application makes the definition of Leggendari decisively appropriate, because it takes real samples to be able to enforce it.
