Given the way Askin was talking about him, I'd say Gremmy probably was one of them. In addition to that, his true form is a brain in a jar, and he doesn't seem to have a Vollständig just like Pernida and Gerard. This is indicative that he may have been a part of the Soul King (seeing as how the Soul King is divided up and scattered all over the place, why not?)

Not sure about Royd. He did own Kenpachi and held his own against Yama, so maybe.
