'Pokémon Sun and Moon' updates: More Pokémon; Zygarde and Grubbin evolutions

More Pokémon have been revealed for the upcoming "Pokémon Sun" and "Pokémon Moon" games for the Nintendo 3DS.
In a new trailer from The Official Pokémon Channel on YouTube, new Pokémon were introduced, as well as evolutions of the previously announced Pokémon, Grubbin and Zygarde.
First up is Tapu Koko, an Electric/Fairy type Pokémon and the Guardian of Melemele Island. Tapu Koko's main ability is Electric Surge, which will allow it to unleash an electric current on the battlefield.
Although Tapu Koko is considered the deity that protects the island, it is described to be fickle. The fairy Pokémon can also learn the move called Nature's Madness, which will take down an opponent by slamming it, reducing its health points by half.
Drampa is another new Pokémon that looks like an old dragon. Indeed, Drampa is a Normal/Dragon type that possesses the abilities Berserk and Sap Sipper. There's also the Water/Psychic Pokémon Bruxish, which has the abilities Dazzling and Strong Jaw. Another Fairy type Pokémon revealed is Cutie Fly. Also a Bug type, Cutie Fly possesses the abilities of Honey Gather and Shield Dust.
Another adorable pocket monster is the Electric/Steel Pokémon named Togedemaru, which is a bit similar to Pikachu. It has the abilities Iron Barbs and Lightning Rod.
Meanwhile, the new trailer also revealed the evolutions of Bug type Pokémon Grubbin and the Dragon/Ground type Zygarde. Grubbin's second stage is called Charjabug with the ability called Battery. This monster can "store enough power to run a household for a whole day," according to the description from the game's official website. From Charjabug, the Pokémon will then evolve to the Stag Beetle Pokémon called Vikavolt.
For Zygarde, it will evolve into its 50% Forme until it reaches its Complete Forme, which is the version of the monster intended for battle. Only Zygarde can learn the move Core Enforcer. According to its official description, if the opponent has already "used his move on the same turn," its Ability will be erased when Zygarde successfully used Core Enforcer.
