I need help to answer 5 riddles?!

I am a favorite of a powerful trainer,
My one attack is weak, that there's a no brainer!.
To evolve I must fuse with one of my own,
But when I evolve, my attack list have grown

I do not have 9 lives
So I live for the night!.
Touch me and you may find love

A cold wind blows through the night
You sense danger and fill with fright
You turn around and hurry to go
But you didn't see me in your shadow

A very patient Pokemon is what clearly describes me;
Why, not even Wobbuffet has such patience as me!
I lay unmoving waiting for evolution to be found,
My evolved form gains a type that's not immune to ground!.

With a certain snake, I'm a mortal enemy,
As hating as any foes could ever be!.
A bloodred Letter adorns my chest,
And Find My Name Somewhere In "Zest"!.Www@Enter-QA@Com
