So what do we think "awakenings" actually are? If we accept that the Zoan guards in Impel Down were awakened, then for them it seems to be a power boost. But here, Doflamingo is using to to affect his environment. Does each type have a different type of awakening?
I expect this to be the case. And I expect it to vary greatly depending on the traits of the regular DF power (especially for Paramecia's).
For example, Fujitora's comets coming down could be an awakening for all we know (opossed to him touching enemies with his blade to intensify gravity). Maybe Magellan's Venom Demon attack/form as well (since it affected environments too, not just organisms) Just speculation offcourse, but there have been a few DF users that did more than their power initially implied.
As for the more obvious ones, I agree that Punk Hazard's state is probably also due to awakening, since opposed to just having a burned island, one half was still an active sea of flames/magma. I also agree Crocodiles Zoan comments are significant, thus Zoan awakenings already being clarified. And to add to that, I think Chopper already reached that with the use of drugs (monster point).
