Many people speculated that Ryokugyu would be a Zoan since Fujitora is a Paramecia and Kizaru is a Logia, thus making it one DF type per Admiral in this new Admiral trio, but this isn’t the case. Kizaru is not truly a part of the new Admiral trio. He isn’t a secondary color, like Fuji and Ryo, and he will soon be killed/retired and replaced by an Orange Admiral, thus completing the secondary color trio. This new Admiral will also be a Zoan to complete the Paramecia/Logia/Zoan Admiral dynamic. I speculate that Drake will be this Orange Admiral since he is one of the most prominent rising stars of the Marines, a part of the Worst Generation, a Zoan, and he has orange as a prominent part of his color scheme. It’s very unlikely that Ryo is a Zoan since we know that his power allows him to live without eating, so he is most likely a plant Logia, allowing him to gain energy through photosynthesis.
