Probably the only Pokemon that's actually cool. The only Pokemon who seeks world domination and plots for him and his clones to inherit the world. He is the most powerful of all Pokemon and can withstand anything that comes his way.

Power manifested in a creature so vile, it makes you tremble to think how humans, through DNA splicing and engineering, were able to create such a monstrosity. Mewtwo is more than a pokemon, it's an example of the kind of power us humans would like to possess; that's why everyone connects with it and makes him the victor against any other creature. There's Deoxys, Lugia, Ho-oh, Groudon and Kyogre, there's Palkia, Dialga and even Darkrai but nothing really compares to the power and willingness to cause harm that Mewtwo possesses. It would be interesting though to face off Mewtwo against Arceus and witness Mewtwo obliterate Arceus from the inside out with the power of his mind done with but a single blink of his eyes!

The most awesome Pokemon ever. Originating from the cells of Mew, he was cloned, but when activated he quickly learneed his supposed purpose, grew angry, and destroyed the laboratory, killing many people. In essence, he is the only Pokemon cool enough to kill you, your friends, your family, and still be able to mix a refreshing drink out of your blood, and intestines.

Just owns, pure owns

It is totally unstoppable, usually goes on killing sprees.
It tries to kill pikachu in a movie, but fails

It hides in a cave near Cerulean City and kills anyone who enters, unless you have a master ball.

The master ball is your only means of survival against this monster

1) The one Pokémon whom enjoys killing.
2) Coolest, Pokémon, EVER!

To be so damn wicked cool and badass,especially for a Pokemon of all things,that you got put in Super Smash Bros. Melee as a secret character.

Used to be the most powerful Pokemon in the world. But then things started getting pretty complicated, and all the Pokemon became Gods with power over every single thing in the world. Then Arceus came along and said "GTFO," so Mewtwo had to sink back into the shadows and stay there until the last page of the internet. Now they got some Yin Yang Pokemon, who are rumored to be able to control Arceus, which makes no sense since Arceus is supposed to be the creator of the universe, and I don't really don't think Arceus would create it's creators. So then a bunch of fans rose up and said "I am disappoint," and Nintendo's trying to make it look like they're making it like their favorite games, Red and Blue. But really it's just a bunch of BS, and so people kept saying "I am disappoint," so now Nintendo's just keeping going. And now I am going to play Crystal.

The greatest pokemon aside from Slowking. He can spin your ass 360 degrees if you aren't carefull. Hell, his purple laser shit can fuck anyone up. I swear, he's on drugs or something, his eyes glow!! Wait.. MAKO ENERGY! HOLY SHIT! IT'S CLOUD!!

The most badass and homocidal Pokemon of all.Created by a mad scientist of Team Rocket many years ago.It was created by taking Mew's genes and fusing it with genes from other Pokemon.

In "Mewtwo Strikes Back",it created an army consisting of all 3 Kanto starters,Ninetales,Vaporeon,and many others.Theese clones were stronger than the originals and nearly killed them all.But after a mushy moment,all the clones (including Mewtwo) left.In "Return of Mewtwo",Giovanni tries to re-capture Mewtwo but eventually falls to Mewtwo's awesome power.

In the games,it is only catchable in FireRed & LeafGreen.After defeating the Elite Four,you can return to Cerulean City,find the cave,and catch a Lv. 70 Mewtwo.It is the only Pokemon in FR & LG that sits at Lv. 70.
