Sen

Sen is a crow soldier created by Dark Corvo on behalf of Dark Raven. They are considered to be one of Billy's most brutal and violent enemies, right behind Dark Corvo and Dark Raven themselves.

Appearance abilities and personality
Sen takes the form of a large raven with the only piece of clothing they wear being a hooded maroon red cloak with the crescent moon crow army symbol on the chest and an orange ring around the neck. Their talons are pitch black while their legs and feathers are a respective light grey and dark purple. Their eyes are bright green and they are at the point of being pupilless. Their most definitive part on their body are the two large wings on their back, which is larger than the rest of the crow army's.

Sen's abilities are the many souls they possess. Their souls allow them to perform attacks from a distance and create multiple copies of themselves. They can fly for long distances thanks to the wings on their back and can even warp the very reality of the world around them and their enemies.

Sen's name comes from the Japanese word of the same spelling literally meaning one thousand, because as they claim to Billy during their second fight "We are many and you are only one." ("私たちは千人として戦います、あなたはただ一つとして戦います. " Watashitachiha sen hito to shite tatakaimasu, anata wa tada hitotsu to shite tatakaimasu. We fight as a thousand people, you fight as one.) They are shown to be confident in their abilities and doesn't show one sign of mercy or hesitation when tasked by their master. They developed a habit of using plural words such as "we" "our" and "us" since they are literally thousands of soldiers in one body.

Gender
Despite using plural words, Billy and his friends use words such as "he" "him" or "his" considering them as a single entity. Sen's gender is classified as unknown and using him was the closest to describe their gender. They are not called "it" because calling them it was considered rude and demeaning. Rolly sometimes used words like "her" or "she" and even asked herself if Sen was a male or a female.

Creation
Sen was originally a single crow soldier who had been defeated by Billy sometime during the events of the first game. The crow soldier was left to die after the crows retreated after Dark Raven was defeated, but Corvo took the deceased soldier along with nine hundred and ninety-nine other souls of his master's deceased followers and soon began a resurrection spell that would not only revive them, but also make them stronger. The result caused the souls to fuse into one and gave them magic that surpassed the elders. The soldier renamed themselves Sen as a tribute to their master and savior in their time of need.

Billy Hatcher: The dark empire
Sen made their first appearance in Billy Hatcher: The dark empire after Dark Raven ordered Corvo to create a soldier so powerful, not even Billy could defeat it, to which Corvo replied that he already did. The crow king then sent them and gave them a single objective; find and capture Billy Hatcher. They were successful at finding him and defeated him in only thirty short seconds. To add insult to injury, they went to the Hatcher residence and kidnapped Jenny Hatcher and made the two watch Raven's new empire grow. Two weeks later, Sen became a top enforcer for Dark Raven and was tasked to destroy anyone who resisted the crescent moon crow army. They met up with Corvo and began to fight Bantam, nearly killing the oldest member of the human group in the process. After Billy saved Bantam, a bemused Sen challenged the hero of Morning land to another fight and, despite their best efforts, was defeated by the boy. Despite this, they easily beaten Billy and, feeling he was too weak to finish off, left and returned back to the crow king satisfied by their victory. Later on, Sen was approached by Corvo, who wanted to know if there was anything else to conquer in Morning land. Sen, though successful in kidnapping Katey Cooper, was disappointed by the lack of worthy opponents that they were receiving until a young Jenny approached the crows, frightened. Sen, amused that Morning land would consider sending a 'trembling child', went up to Jenny and gave her an ultimatum; they will allow her to run away and live, otherwise they will kill her if she stays and fights. In spite of Sen's choice, Jenny decided to face them, to which they responded that she will learn fear, pain and agony. They finished the threat by stating that Jenny's fear, pain and agony will end shortly. They fought each other to a stalemate (with Sen displaying traits of social Darwinism, saying that the strong always survive) and they mistakenly assume that Jenny was Jenny Hatcher's daughter and attempted a deadly blow with an energy shot. The attack phased through Jenny's body, leaving her unharmed thanks to a gem she found earlier that day to Sen's shock and confusion. They knocked Jenny back and left the area, allowing the humans to contemplate the inevitable until Dark Raven's plan finishes their enemies for good. When they learned that Raven's castle was raided for Corvo's spell, Sen became disappointed when Corvo called for a technical retreat, calling it an act of cowardice. They were approached by Billy again after they kidnapped Johnny and Jenny, ready to kill them under Raven's orders until Corvo mockingly allowed Billy to fight Sen as their power was only half way charged. During the fight, Sen distracted Billy long enough for their power to completely charge and successfully did so until a young Johnny and Jenny joined Billy against Sen. The trio were able to defeat Sen for good as they struggled to understand why Billy was more powerful than them. They were then sent struggling back to Raven's palace, despite their pleads of them still being able to fight back. It is unknown what happened to Sen afterwards.
