Personality: 

More crazed and psychopathic than one could believe, Ripper was nothing short of twisted and sadistic. He fully enjoyed wanton slaying and hunting Unions. Despite possessing a Crystal and being utterly devoid of any positive emotion, Ripper was fully mentally capable, being clearly able to devise cunning strategies to give him an advantage in combat. He was also somewhat sharp, being able to discern Es as not being human after she dodged one of his attacks. He was also well known for doing what he wanted, which eventually lead to his demise.

Ripper was also barbarically sadistic, only getting any real joy out of his opponents helplessness and scared emotions. When Es failed to reveal any emotions for him to thrive off, Ripper commented on her being boring, asking if she was 'as dead on the inside as she is on the outside'. In order to help strike fear and panic into his prey's hearts, he also possessed multiple bombs that were molotov-like in their design as they ignited the area around them.
