Aside from Sky Battles, Pokémon X and Pokémon Y will also have something called Horde Encounters. These are instances where you’ll face multiple wild Pokémon all at once—with only a single Pokémon on your side.
Horde Encounters are possible when Pokémon like Hondour, Axew, Tauros and Miltank appear en masse in the wild.
Additionally, The Pokémon Company has revealed another new set of Pokémon that will debut in Pokémon X and Pokémon Y. Check them out below:
An evolved form of the recently announced Fletchling, Talonflame, is a Fire- and Flying-type Pokémon that gains a whole new level of speed and firepower. Reaching speeds of up to 310 mph when diving for its prey, Talonflame can attack its foes with devastating kicks while embers spew from its body as it zooms through the sky. Talonflame knows Brave Bird, one of the strongest Flying-type moves. Use Brave Bird carefully, though, because the incredible strength of this move also does damage to the user.
The Water Gun Pokémon Clauncher uses its one oversized claw not only to seize prey but also to shoot condensed water at others as a projectile. This capability is so intense that it can crack a boulder! A Water-type Pokémon, Clauncher can also use its giant claw to crush opponents with the powerful Water-type move Crabhammer, which is more likely to land a critical hit. Critical hits against opposing Pokémon will do twice the usual damage.
Some would say that the Poison- and Water-type Pokémon Skrelp appears to be nothing more than a rotting piece of kelp, but don’t let its appearance fool you. Using its unique look to its benefit, Skrelp pretends to be a piece of seaweed, and when prey wander past it, Skrelp bathes them in poison so they can’t struggle when it attacks. Skrelp uses the Poison-type move Sludge Bomb, a move that can leave opposing Pokémon poisoned. A poisoned Pokémon will slowly take damage over the length of a battle.
