Roark in “O'er The Rampardos We Watched!”

You were great Onix. Thanks, now take a nice long rest. That was quite an impressive move you just made. You blew back all that debris and pulverized Onix's Stealth Rock at the same time. And I don't need to tell you how difficult it is to cause Onix any damage at all. [Roark's tactics may have worked once, but the one thing Gym Leaders have to learn when it comes to a rematch, a previously defeated opponent does not give repeat performances]
