Remember Mimikyu, the lonely Pokemon that wears a Pikachu costume to hide its ghastly true form? Thanks to Pokemon Go's upcoming Halloween event, we've come around full-circle to having a Pikachu dressed up as a Mimikyu. This self-cosplaying Pikachu, other costumed Gen 1 starters, and more will be available during Pokemon Go's Halloween event, running from Thursday, October 17 through Friday, November 1.
The Halloween event is also introducing Yamask, a Gen 5 ghost-type, to Pokemon Go (same goes for its shiny variant). Yamask and the costumed Pikachu can both be encountered in the wild. All throughout the event, encounter rates for Ghost and Dark-type Pokemon will be increased in the wild, through eggs, and in raids.
Speaking of raids, the other costumed Pokemon and a legendary Pokemon from Gen 4 will only be found in raids during the Halloween event. The three classic starters from Gen 1 round out the costumed set: you'll find Charmander as Cubone, Bulbasaur as Shedninja, and Squirtle as Yamask in raids. All four costumed Pokemon will also have a chance of appearing as shinies. Darkrai will make its Pokemon Go debut in five-star raids.
On top of candy bonuses, research tasks, and a return of last year's Spiritomb quest, the October 17 update is also introducing some more permanent changes to Go. Over a dozen Pokemon are being added to the selection that you can rescue from Go's version of Team Rocket. The Style Shop will get some new trainer outfit items, including a Pikachu onesie and a Mimikyu bag.
As for Pikachu and its Mimikyu costume, it just seems a little cruel for Pikachu to co-opt Mimikyu's identity, doesn't it? All poor Mimikyu wants is to be as popular as the Pika, and now Pikachu is taking the one thing it has—it's unique identity. As always, we're Team Mimikyu.
