I came up with some nicknames for my Pokemon.
Here they are:

What? It makes sense...

The name speaks the truth!

I nicknamed it Rainer for a Vaporeon, because it's the strongest of the three.

Haha I have no inspiration...

What? It's a Bug/Poison ;-;

FEARow? Get it?

He looks like a Miles to me...

Part Flying, part Normal.

Hail Hydra!

And that's it so far.
