Well discounting the urburn myth/theory that PH was an 'unfair' showing of Smoker's capabilities coz(ding ding ding) he showed nada/zip/zero from his df so(pout face on) he just gotta have something new from his df ryt? As if there was some rule or manuscript that stated that after the time skip he wld have new tricks outside of strenght n speed boost plus haki, which is actually a lot. If u remember necessity is the mother of invention so why the heck wld he have df based boosts when in paradise(grand line part1) his df is all he needed to stand on pedestals so far above Luffy n company, now however that it's been shown that being just a logia(another Caribou) ain't enough can we expect some out the box utilization of his fruit in conjunction with haki and or with other power ups.
Uzumaki Macho slayed this coz really what feat is there of Smoker's that u can say without having to say "ahhh well coz/well we gotta give him credit atleast coz"(excuses excuses excuses).
Honestly Crocodile is more impressive than Smoker considering Croc at MF, just saying.
