Pokemon Legends
Mewtwo
As Mewtwo was a created Pokemon, I was extremely reluctant to do an entry about it. But as it has been classified as a 'Legendary' type, I have done an entry about it anyway.
Mewtwo, the Genetics Pokemon, created solely for battling. It was created on Cinnibar Island, before it destroyed the laboratory there. The ruins of the building can still be seen. Mewtwo isn't actually an entirely new, created pokemon. It is a clone of Mew, one of the three most powerful pokemon in the world.
The science crew, needing funding for their expedition for their journey deep into the forests of Janera, in a search to see if Mew was real, posted an application to the Indigo League of Kanto. Somehow the application was intervened with, and instead was sent to Giovanni, leader of Team Rocket. He gave the Science Crew money, but in return, they needed to create the most powerful Pokemon in the world.
They failed, but only just. Mysterious things happened during the early experiments, and Mewtwo's predecessors all died. And then, halfway through Mewtwo's growing process, another accident happened. Mewtwo survived, but it hadn't grown sufficiently to know the true meaning of emotions. Nor did it have a compassionate heart.
After destroying the lab at Cinnibar, it was soon picked up by Giovanni. Little is known after that, but during that period, it learnt to control its overwhelming psychic powers.
It soon reappeared. It set up a Palace on New Island and took the title "World's Greatest Pokemon Master'. After which, it started looking for challenges, sending out flying types to video-tape battles and then inviting the victor of the battle to his Palace.
Buthe wasn't letting the unworthy challengers to his palace quite that easily. It stirred up the weathers, drawing clouds and thunderstorms worldwide to one place, creating a copy of the legendary 'Winds of Water', the storm that almost left the planet lifeless. Only the best of the best challengers braved the storm, using their pokemon. Among these: Ash Ketchum, the International Champion.
Once all challengers where at Mewtwo's palace, Mewtwo challenged them to battles. Each challenger lost, and Mewtwo claimed its prize: Every one of the Challengers Pokemon.
Somehow Ash intervened, and after being killed, and then resurrected by the Pokemon nearby, Mewtwo disappeared, taking his clones with him.
The next reported sighting of Mewtwo was in Johto, a currently classified location. Giovanni, the head of Team Rocket, managed to find Mewtwo and took an attempt to capture it. The attempt failed when Ash Ketchum intervened again.
Very little is known about the actual creation of Mewtwo, but I managed to find several facts about it. It was only created when the Scientists creating it combined, and recombined, its genetic code.
Mewtwo is the clone of Mew, meaning that it should not be trifled with. Mew, the Creator of Life, is powerful, and the Scientists creating Mewtwo tried to make Mewtwo stronger than Mew. They succeeded, and almost destroyed the world as a result.
