How to Get Cosmoem in Pokemon Go 

The Season of Light brought the Legendary Pokemon Cosmog into Pokemon Go. Trainers who complete the A Cosmic Companion Special Research Storyline will be rewarded with the small Psychic-type Pokemon.

But, as Pokemon aficionados know, Cosmog can evolve. In fact, it can evolve a number of times and in a number of ways. With the start of the Evolving Stars event, trainers will finally be able to evolve Cosmog into its middle stage, Cosmoem.

To evolve your Cosmog, trainers must use 25 Cosmog Candy on the Pokemon. This new Psychic-type still won’t be able to evolve into its final form but we’re guessing that’ll be saved for another time.

Also, if you’re worried about evolving the one Cosmog you have, Niantic has teased that trainers will be able to capture more Cosmog in the future. So stay tuned.

Mega Gyarados Raid Day 

In the middle of the Evolving Stars event, Pokemon Go will put on a special Raid Day focused on Mega Gyarados.

The powerful Water and Dark-type Pokemon will appear more frequently in Pokemon Go Mega Gyarados raids for three hours this Saturday, October 8 from 2 p.m. to 5 p.m. local time. 

To help trainers get more chances at battling and catching Gyarados -- and earning more Mega Gyarados Mega Energy -- they can receive up to five additional Raid Passes by spinning Photo Discs at Gyms.

And if you’re thinking you have enough Mega Energy or the perfect Gyarados, the odds of encountering a Shiny Gyarados in these Raids will be increased.
