User blog comment:Feroza/How will Luffy awaken. THEORIES./@comment-26058050-20161018144824

Couple of things I want to point out.

Luffy has already met more of the Roger pirates, namely Nekomamushi and Inuarashi, and yes even though they were there only for a short time, they were still part of the crew. It's still possible that he might meet more afterwards, but your pattern with the Roger pirates is a bit fragmented, not to mention that Buggy, who was also a member, appeared before Crocus.

Secondly with Chopper and the NHC10, I don't think he uses it in his rumble balls. Just by his reaction alone you can tell that he is angry that NHC10 is being used. We do know that he learnt about it from Kureha, but that's not solid enough evidence to show that he would use it, plus he would have to have a steady supply of it in order to make new Rum Balls, and since it can only be used by select individuals and is considered a narcotic, there is no way he could gain access to it.

Finally with Awakening itself, we know very little about it. The only known awakening devil fruit users are the 4 jailer beasts and Doflamingo. Could Doflamingo be involved with taking drugs, maybe, but I doubt it, and he displayed no use of taking anything before using his awakening powers. The Jailer beasts on the other hand, yes they are extremely large, but who is to say that it's the result of awakening? Crocodile, who has a large knowledge of DF's, said that awakening Zoan types are extremely resilient/durable and can recover quickly from injury. That to me seems definite, which has no correlation to their size. It can of course be argued that they are that huge because of years of physical training (e.g look at Lucci) or the fact that their human forms are of course large beings to begin with, as we never saw what they looked like (also this is the world of OP, size seems to be interchangable and not unique).

Since paramecia has a wider variety of DF powers, such as creating things or having a defensive power (such as being made of rubber) it's hard to pinpoint what could be the abilities that awakening DF's give, we've only seen one Paramecia user. Can it be simply trained, and how can someone train someone when, as I said, paramecia DF's has a wide variety. If for a moment that Scopper was going to train him, he would have to have the knowledge of being able to awaken that specific powers (especially since luffy's DF is more of a defensive type). And no I don't think Roger ate the Gomu Gomu fruit, Oda may be good at sublety, but the fact that the world knows about Roger, especially the world government and Marines, I think it would have been stated long time ago that he has the same DF powers.
