...Anyways I am now thinking...
Diaruga is like Groudon...
Parukia is like Kyogre...
Lucario is like Rayquaza...
Not really but thats the way they fill the slots... Diaruga and Parukia got the covers like Kyogre and Groudon, Rayquaza was the big one on the game, Lucario is the big on on D&P most likely also...
