Alright everyone, its time for some holiday fun!
Guess these pokemon and you are sure to have some!

I see what you try, but it won’t hurt me
Reflected it is, by ability

I was second thought, the fourth actually,
But I was the first, to like it sunny

My brother is good; don’t count me out yet,
One of those new moves might put him in check.

Who am I?

I hope all these ones I wrote aren't hella shitty.
