Good chapter, I think a Logia fruit will bring the biggest advantage in the future (especially in other universes without Haki). He already has a dragon form so a Zoan fruit is useless and his skills and abilities cover the funtions of multiple Paramecia fruits. To be able to turn into an element and control it completely (i.e. awakening the fruit) gives you a lot of defensive and offensive potential.
If it's a devil fruit than it should be; Endemon zoan devil fruit Human-human fruit~model Lucifer(able to get power of Lucifer) Hydra-hydra fruit(able to become hydra with many heads and control all elements) Human-human fruit~model susano version(ability of MS susano and EMS susano in awakening fruit) Human-human fruit~model sparda(ability of Dante, Vergil, Nero, Sparda etc in devil trigger and sin devil trigger in awakening state) Giant-Giant fruit~model titan form (abilities of titan from Greek or ability from AOT) Logia devil fruit Wave-wave fruit(able to control waves and wavelengths such as light wave, sound wave, radio wave, magnetic waves etc) Metal-Metal fruit~model liquid metal(can manipulate metals in liquid or solid form or even gas form if fruit is awakened) Teleport-teleport fruit (obito's kamui and in awakening fruit it can teleport in another dimension such as narutoverse, nasuverse etc) Paramicia fruit Creation-creation fruit (to create any thing except living thing) Energy-Energy fruit (able to control nen, chakra, ki, mana, etc) Energy-energy fruit (such as nen, ki, chakra, mana etc) More-more fruit (lower version of boosted gear) Less-less fruit (make everything less such as by making enemy stamina, energy, power, etc less) (lower version of divine dividing) Control-control fruit/manipulation-manipulation fruit (able to control everything that he/she think she can control such as if he/she think land/earth element can be control it will be control/manipulate )
