It will then evolve into the next stage at which point it will have a snake like appearance. The Pokémon will be at 50 percent power level at this stage. It will obtain its full power during the last stage and in this stage it will have a humanoid appearance.
When the Pokémon is completely evolved, it will become extremely powerful. Its power will be even greater than that of Xerneas and Yveltal, which are two legendary Pokémon that are found in previous Pokémon games.
In other news, some reports are suggesting that Pokémon Z might not happen at all. Apparently, the seventh generation of Pokémon will be featured in Pokémon Sun and Moon. Some Legendary Pokémon will also be added to the game. Some experts are touting this game as the proper successor of Pokémon X and Y.
They believe that developers will incorporate some tweaks and make the necessary adjustments to make it live up to the expectations of fans regarding Pokémon Z. However, it should be noted that there has been no official confirmation behind these claims and thus they are to be taken with a pinch of salt.
Stay tuned for more update on Pokémon Z.
