>>53737154Im convinced onix was intended to be a lot stronger then it is. They wanted brock(the first boss of pokemon) to have a big cool pokemon that was reasonably defeatable so they likely siphoned its attack and special stats and pumped it into its defense. This also might be why both rock and ground are weak to grass and water so 2 of the starters could destroy it. They obivously over did it though as squrtle completely decimates the first gym and onix is complete trash.
