uh.... you know you just proved me right, right? By stating that with Azala and her Black Tyrano still in the picture that the Iokans and Larubians are wiped out, you reinforce what I said about Crono and Co. being the deciding factor.
I admit to being wrong about the Iokans as they were strong enough to fight the reptites on their own, but Ayla was still the strongest of them all, but they would not have won the war between the reptites on their own, with Lavos out of the picture.
