Is there any games similar to pokemon for the iPod touch?

I have gpsphone but I've beaten all the pokemon games a million times. I don't want a game like mydinos go! Where it's like mafia wars from Facebook...I also tried pocket summoner which is closer to what I want but you don't actually battle any games like this?|||There really is no game like Pokemon on the App store. There are games that try and copy the concept but they all suck. I would be surprised if one didn't come out though.
