MewTwo
Mewtwo
can beat any pokemon. As explained in the first movie he can make a hurricane
that can destroy the planet. He has a very high intelligence, hence he was able
to rebuild the laboratory with no experience in that subject.
Arceus
Arceus is the most solid rock hardcore of
the legendary pokemon ever! He or she is the creator the creator of the pokemon universe whereas nobody
knew the pokemon's real name so they adress him or her as the original one.
Apparently the ancient Greek philosophers have name the original one as Arceus,
his or her history goes way back not only did Arcues created Dialga to be the
guardian of time, Palika to be guardian of space and Girantina to be guardian
of the Disortian World as explained in the 12th movie of Pokemon Arceus created
the jewel of life to restore a wasteland using the tablets of the elements only
to betrayed but the timeline has been restored to stop the destruction of the
Pokemon universe.

Mew
Mew
can learn all kinds of moves and can use transform to its advantage in battle.
An awesome and friendly choice for a legendary friend.

Lugia
Lugia
is probably one of the best pokemon I have in Soulsilver and it beats Giratina
in many ways, extrasensory a few times and before you notice Giratina has
fainted even if it is levels higher like level 50.

Rayquaza
It
is the best pokemon which defeated even deoxix "all hail RAYQUAZA"
Darkai

Darkai has been my favourite Pokemon since
I watched the Pokemon movie in which he stars in. Along with water types, I
love dark type Pokemon. Also, Darkrai, is supposed to cause those who are near
him nightmares. Because of that, the creators based him off a few characters
from horror films .
Giratina
Its funny cause when I got diamond all
ma buds were like dude pearl better. So when I got Dialga, they stood no chance
CAUSE DIAMONDS EPIC but when I found Giratina, beat all my buds in one go.
That's why Giratina is PWNAGE, PWNAGE AND MORE PWNAGE
Ho-Oh
It's Special Defense is so high
together with Calm Mind it is very hard to beat.
Combined with it's Special Attack it's a VERY powerful opponent to beat.
Dialga
Great, massive, its got everything.

Zekrom
Zekrom is a humungus dragon who made the world in pokemon white and black.
