On Friday, September 1, Niantic Labs and The Pokemon Company announced the arrival of Legendary Pokemon Raikou, Entei, and Suicune via a blog post on the game's official website.

Starting today i.e. September 1, all of these coveted creatures will make an appearance in Raid Battles and Trainers worldwide can look ahead to squaring off against these creatures along with friends in a bid to capture the triad of Legendary Pokemon that hails from the Johto region.

Catching Raikou, Entei, and Suicune

As expected, getting your hands on the aforesaid Legendary Pokemon will be no child's play.

If an update to the hit mobile game, "Pokemon Go" GAME_MASTER file is anything to go by, Raikou, Entei, and Suicune will all boast base capture rates of just 2 percent. This makes them even harder to catch than the Legendary Birds that were spotted in the game this August.

Before any sort of bonuses are factored in, the base capture rate data considerably influence how easy or hard it would be for a Trainer to catch a specific Pokemon.

Base capture rates and why do they matter

Although several bonuses including accurate throws, Razz Berries, and curveball increases a player's chances of catching the legendaries, they still have approximately 16 percent chance per throw of seizing Raikou, Entei, and Suicune even after all the bonuses have been factored in.

Lugia, Zapdos, Moltres, and Articuno originally came with base capture rates of just 2 percent, but the game developer recently increased base capture rates of Articuno, Moltres, and Zapdos to 3 percent, announcing that each of these creatures would be available for nearly a week at a time.

It's worth noting that the company did not change Lugia's base capture rate, keeping it at 2 percent.

According to a report from Comicbook, Niantic decided to leave Lugia's base capture rate as it is since it was up for grabs for more than a month.

Much to Trainers' delight there will more than enough time to catch the Legendary Pokemon. Each Pokemon is slated to make an appearance in a different multi- continent region for a whole month one by one before heading to some other continent the following month.

Further making things easier for the Trainers, Niantic Labs took care of a bug that restricted them from being able to capture a Raid Boss using their last throw.

The Legendary Pokemon are starting to burst forth worldwide. Trainers will have to battle hard and even waste a few Premier Balls in a bid to catch this infrequent and strong Pokemon.
