Gray's not unbeatable. He's just...really good at what he does. xD

Especially considering he has a Gible and it can use Dragon Rage. A fixed amount of forty damage is devastating early on. It seems that Gray has been a ground type user so far. I mean, Nidoran is poison, but at its final stage, it's poison and ground, if I'm correct.
