I would wager that Quote and Curly weren't created officially by any countries of the earth.
Before, a great number of-
us robots were sent to-
this island...
We were sent by the-
countries of the surface.
The purpose of the mission...
it was the incredible-
slumbering power found on-
this floating island...
And it was also about the-
Demon Crown.
But you and I were different.
We were sent on a mission to-
destroy that power.
Sounds more like an independent group or creator (or "traitor?") sent Q and C on the mission to destroy the Crown.
Chances are the same person who created them sent them on their mission.
Still, andwhyisit is right... there is nothing to point to Q and C's origins or creator. Or even if they are both made by the same creator...
Although it's very highly likely they were created somewhere off of the island :
Um...
Are you from this island?
You don't seem like you are.
The letters on your cap-
aren't from here.
Curly>I'm not from around here.
Maybe you're lost?
For a robot you seem to have-
human emotions.
You are different from the-
others who came here-
many years ago.
Not only are they very unique...
But, after completing their mission on the island; they roam freely... not returning to base or their creators. Very odd...
Although, it's good that they don't return; at least if they were created by one of the countries of the surface :
I had heard that they were-
all destroyed after the war...
However, I don't know the-
exact details.
Sounds like anyone who returns will be dismantled...
EDIT: oh yeah, one more thing...
Whoever created Quote and Curly Brace have an odd naming convention... (unless it's standard for robots?)
That could be a clue that both were created by the same person...
