Legendary Pokémon

Here I am with another game! Let´s see if we can make this forum more alive.
OK, in this game, you post 3 tips about one pokémon. The next person must to say which pokémon is this!
For example: I´m yellow. I have a lightning-shaped tail. I evolve with a thunderstone. Who am I?
The next person answers: Pikachu!

Understood? Let´s see how much we know about pokémon!!!

I´m very light.
I´m the fastest pokémon while it´s sunny.
A few people use me on battles.

Who am I?

Knowing you and seeing it in your sig, it's Jumpluff, isn't it? If I am right, tell me so I can post the next tips.

Of course it is.^^ I started being nice... Your turn!

Ok then. Here we go:

1. I can fly.
2. I have been the protagonist of a Pokémon movie.
3. Pokémon XD gave me 2 pretty nice moves.

Easy one.

Is that Lugia?

Of course it is... I knew it was veeeeeery easy... Next tips!

Are only ninjomewtwo and I who play this game??? C´mon people!!!

I´m a perfect teammate to Groudon (in a double battle)
I´m quite rare.
I´m quite cute too.

Who am I?

OK, I'll try since nobody else does. Meganium?

We don't know. Is it Jumpluff again? Aluado could you post more tips?

It´s not Jumpluff... Jumpluffs aren´t rare, are they?!
OK, guys, the same pokémon with other tips...

I´m a perfect teammate with Groudon.
I´m quite cute.
I´m a pokémon of the 4th generation.

Now it´s really easy guys! C´mon!!!

Your turn, Treecko! (Ah, the right name is "Cherrim", ok?)

If you mean pretty fast for a tank, then Deoxys' Defense form. If not, then Aruseus?
