Those who purchase either Sun or Moon by January 11, 2017 will receive a unique Munchlax, which evolves into Pulverizing Snorlax.
This Snorlax holds the item Snorlium Z and can use a Z-Move called Pulverizing Pancake. Munchlax will also use the move Hold Back, which it could not normally learn. Hold Back is an attack move that leaves its opponent with just 1 hit point.
Finally, the Pokemon will know the move Happy Hour, another it normally couldn’t learn. When players use Happy Hour during a Trainer battle, they’ll receive twice as much prize money after the battle.
Munchlax - Normal
Munchlax is a big eater that wolfs down its own weight in food once a day, gulping it down practically without chewing. It also hides food under the hair on its body. But then it forgets about it.
Snorlax - Normal
Snorlax is a Pokemon that has blocked the path of many a Trainer. It’s not satisfied unless it eats in excess of 880 pounds of food every day. When it’s done eating, it promptly goes to sleep. Snorlax’s typical day consists of nothing more than eating and sleeping. It gets fatter and fatter, and it moves less and less. Its stomach is extremely strong, and its digestive juices can dissolve any kind of poison, so eating rotten food doesn’t affect it.
An Alolan variant of Rattata was also revealed during the presentation. Alolan Rattata is a Dark/Normal Type Pokemon found in Urban areas of Alolan.
They are nocturnal and live in nests of several dozen. Alolan Rattata have "an excellent aptitude for sniffing out delicious fresh foods." They pay no attention to foods that aren’t fresh. The evolved version of this regional variant, Alolan Raticate, will serve as its own boss.
More news on the latest in the Pokemon franchise will be shared on September 6, per The Pokemon Company.
Pokemon Sun and Moon will be released on 3DS November 18 in North America and November 23 in the UK.
