It was Volcarona!!! The Awesome JustLikePinkiePie!!!!!!!!!!!!

So here's the next riddle!!!!!!!!!!!!!!!!!!!
:

I'm a grass type pokemon because I learn Spiky Shield at level 36 as my signature move

But I learn Hammer Arm at level 60
does it means I'm also a fighting type?

I have 5 weaknesses

And I'm pretty big!!!!!
That's why I'm awesome!

*~*~*

Sorry Pinkie and all of you if it's short and easy!!!
