Although Mew is the last Pokémon in the 1st Generation, it has the DNA of every original Pokémon. Standing at 1’04” in height and under 9 pounds, you wouldn’t expect this adorable Pokémon to be capable of using any attack. Mew can also become invisible at will and is only able to be seen through a microscope. In Mewtwo Strikes Back, Mew battles Mewtwo to save humanity, with Ash Ketchum and Pikachu's help.

This is where things get hairy. Dubbed The Original One, Arceus is the most mythical of any Pokémon.

At 10” and over 700 Pounds, Arceus is imposing in character and ability. Capable of disappearing or stopping time, Arceus is arguably the most powerful Pokémon.

The Pokémon Company

Is this the first shocker in our Most Powerful Pokémon countdown? The mighty Charizard is much lower than you anticipated, right? After all, ‘Zard is the hottest thing going in the card realm, but things are slightly different here. With that said, this was a tough decision, given the ferocity Charizard wields with his Flamethrower. The heat generated can melt boulders, glaciers, and even start forest fires. At five feet, seven inches, and roughly 200 pounds, this fire breathing Pokémon would be a tough test for just about any Pokémon. The third evolution from Charmander and Charmeleon, Charizard is a bonafide member of the upper echelon of Power Pokémon.
