This is just a very cheap bait. You know that.
Absalom, the doctor, Perona and whatnot were part of Moria's gang. They had command over the general zombies by default. No matter how strong, no matter how weak. They even had command over Zoro and Sanji's shadows. And by default they were to have command over Oars, too, after the transition was done (at first, zombies resist and are a lot more independent, as shown by Oars and Sanji's penguin).
Ryuuma was literally Brook with Zoro's physical strength and speed. By every inch of portrayal, feats and existence in general, he shits all over Absalom.
Brook trained for so long and still got destroyed by Ryuuma who held back the entire time. You know whom Brook fodderized BEFORE training? The doctor. You know who the doctor had command over? Ryuuma. Literally meant fuck all.
Absalom was gag trash. Only reason Sanji even took significant damage was over Nami's BS. Implying he has anything over Ryuuma is pure agenda driving.
