Dae asks: Alternate forms

Let’s pretend nothing happened, shall we? You murdered me, but we continue asking. For science. You monster…

What’s the best alternate form of a Pokémon? There are a lot to choose from, so everyone should have something to answer. Whether it is the cool Giratina Origin Forme, or the cute Shaymin Sky Forme. But I think human minds are too weak to pick a good answer. So prove me wrong and tell us why you think you picked the right choice (which you won’t).

I predict there’s a 85% chance you’ll have a hard time choosing between a few options. But do answer, though. There will be cake in the comments below.
