Don

"Imbeciles, your powers are nothing but meager droplets that you've leached from my ocean of power.

I can not be defeated. I'm the fucking cockroach king."

-Don upon absorbing Vee and Bronzo

Don Santiago lived alone within the Room of Swords for over three years before Gyrus arrived with the first Sword. After a significant number of voyagers arrived, he seemed to have assumed a leader-like position among them.

"Black Box" Gyrus implanted Don in his memories as a substitution for Captain Iro.￼

Don is at first presumed to be another voyager, and is introduced later as the crippled leader of them.
