I will let my actions speak for me
Paul is quite, fast speaking when he does speak, and loyal to his group. Paul would rather work on his devices or practice his skills because he has no knack for social interactions. Paul has never seen the point of lying or sugar coating things. His lack of social skills comes from the fact he will tell people what they do not want to hear only if they need to hear it so he tries to avoid conversations normally by either being boring with them or just continuing with whatever he is doing. If he believes he is correct beyond a doubt in his mind he will go with what he thinks is right. If he was wrong he will apologize and put himself in a self torture state to teach himself a lesson for doubting others again.
Paul carries around a bunch of equipment used for hacking, jury rigging, and repairing items. Other then that big load of equipment he carries a Scar-H and a M-9 Pistol holstered to his hip. Though he has guns he is not confident in his aiming capabilities they are about average or maybe a little lower. If he can get the person in close quarters he will take them down with grapples and punches his more preferred style of combat.
Paul was always a silent kid is still silent as an adult. Other then that he has had a fascination with making things better like his body, computers, game consoles, or toys. Later in life these habits got him into vanquisher as a Technical Engineer after he worked as a Computers expert in a big corporation eventually being arrested for hacking a bunch mainframes around the world to see if he could. After one to many times of getting caught he was told to use it for a better use working with the government or be put in jail. Gaining more skill in hacking and keeping up with his habits he signed up for the Vanquish squad. He was accepted for his skill in making explosives, small computers, his hacking capabilities, and his quick learning of gun repairs.
He has seen the field a few times before he was officially put in the Vanquishers to see if he could handle it. Still basically a greenhorn at working with squads he will try his best at working with their weapons and keeping them alive with his skills.
