Hulohot is a middle-aged Portuguese intermediate character from Digital Fortress. He's a professional assassin who gets paid for assassinating people around Portugal and Spain. He generally reports targets as dead before he finishes his job. He uses a really silent suppressor which sounds like a cough when he shoots. He has wire framed glasses, which are something like a hologram computer in reality. His only problem is that he's deaf.
SPOILER! Do not read the rest if you haven't finished the book yet.
His last customer was Commander Strathmore. His last mission was killing David Becker and bringing the ring he holds. After a long chase, when he was just about to kill David Becker, David attacked his ankle with an iron bar, which made him fall down a flight of stairs, breaking his neck and causing his death.
