I don't think that Propheci was meant to stay a Villain. One of DB's themes seems to be the "history repeats itself", and the Prophets helped the Original!DB. Yet, Propheci has given up on humans. They won't change. Helping them once again would be a waste of blood because they will fall in the same mistakes once again in a few generations. BUT Artha needs ALL the Original!DB's alleys to win. But Propheci's loyalty is very difficult to win. It would leed to some interesting character development
This is why I would like a new Prophet character to stand alongside their humans against Propheci, to ally with the Dragon Booster as their ancestors did once. I think that’s something that annoyed me about Reepyr’s rebellion in hindsight, because it was just him riding a silent prophet. It was almost the same as what Propheci did to him, though I understand why Reepyr’s dragon was silent; normally a prophet can only speak through his rider.
But with all the technology they have, I imagine that the prophet gear could be adapted without the mind control. Or someone could invent gear like those voice boxes in Pixar’s Up! that allowed the dogs to speak.
I don’t necessarily think they need Propheci as an ally, at least not at first. Though I would love it if, at the series finale or close to it, that Propheci sees the truth in the end and does something that ends up being everyone’s saving grace. Whether or not that required sacrifice or his death, is presently relevant, but a neutral character who loathed the protagonist finally coming around and proving to be exactly what they needed?
Yeah, gimme more of that flavor of draconee-yum bars.
