Henry is Lakes' henchman, and possibly the most evil and violent Dino in history. Of course he is in the SS but some say the SS are even ashamed of him. Henry has been in the SS for a number of years and was quickly shuffled to an obscure garrison. He proved useless at interrogation, his prisoners always dying too quickly because of his love of using power tools on flesh.
When M-B-H needed an enforcer he chose Henry because he was ultraviolent, but most importantly rather stupid. Henry obeys orders to destroy not because of loyalty but because he likes it. In Lakes' service he has proved not to be that useful as all he wants to do is kill.
In his private life Henry lives alone except for a realdoll, which he likes to violently penetrate. To him every Dino in the SS above the rank of Centurion is gay. He is a Centurion of course.
