That's the only thing that fits as a powerful princess from a distant land iirc.
Or, you know, Drossel, who is a robot princess who knows some form of martial arts, is surrounded by invisible ninja maid robots and constantly attended to by a spidermech whose "fists" can shatter metal, can fly, and has an entire city listening to her.
Who is literally separated by the sum total of 40000 years and change, making her more "distant" from us than anyone on this planet in terms of dimensional distance, as well as the language barrier making her more physically "distant".
And who is
right fucking there and we should probably start looking into anything that could make translating happen, whether that be magic or not.
"Even the locals burn fossil fuel instead of something as primitive as emotion."
Hmm.
So. Gantu found out what was going on. And was unable to free the captives. He was also able to infer that the greater population is unaware of what is actually happening. That paints a bad picture for the number of captives and the capability to transport them easily.
You know, it strikes me - I know KH is supposed to be totally off of this in terms of plot, and fair enough, but I recall the Hostile Program being potentially under Encom control with a new origin. Could that sludgy Unversed monster also be there in Monsteropolis as a "guard dog"?
I mean, it is kinda hard to get more primitive than something almost every single living organism, including arguably plants to a degree, has since the beginning of complex organisms.
Also, the main issue with emotion power in the movie is that it's vulnerable to some damn fool creating even greater emotions around it.
