Powers & Abilities Roger Rocks Garp

[Garps tekkai]

None of them have even left a hint for FS.
Garp should have ID but again, it was not shown.
Until proven otherwise, they do not have either of them.

Garp's impact attacks and Roger's Kamusari and his non touching clash with Primebeard should be ID CoA. No reason for Oda to not give them ID CoA tbh.
I think they might get it confirmed via Shanks and Coby.

But yea no sign of FS yet and other than it's just like you said: until proven otherwise, they don't have it.
