I wonder what some of the characters would think of when they hear Siarnaq's backstory...
Siarnaq:

His personality is monotone and robotic, making him seem almost lifeless. He is shown to be computer-like, and his speech is capitalized, making him seem more like a Mechaniloid than a Human/Humanoid/Reploid (for example, asking to "INPUT RESPONSE" and declaring "INCOMPREHENSIBLE"). Other than that, he seems to have no personality at all, except being at least slightly sadistic, as when the player is defeated by him, he will be heard laughing dementedly. He is known as the "The Shadow Mega Man." (Please note that in ZX and ZX Advent those who use Biometals are known as "Mega Men" such as with Model P "The Shadow Mega Man."
He was a former Hunter and assassin for hire whose past includes being
betrayed by his friends and left for dead. This is the reason for his cold, impassiveness toward others.
