Mr. WPNZ

Mr. WPNZ assumes a paternal role with Cory, Katie, and Zack, but his parenting style is twisted and extreme. He disguises questionable practices as games, such as weapons training, encouraging them to become killers like their mother in the past so they can be as strong as he and his mother were when they were assassins. He is ruthless and reckless in achieving his goals, such as turning innocent people like Mario into practice targets and injuring Karen's allies to isolate her. Obsessed with Karen and her children, he relentlessly stalks them, forcing her to keep them hidden. His expertise in weaponry and mechanics, coupled with his aggressive behavior, makes him extremely dangerous, often requiring multiple people to subdue him.

Mr. WPNZ is, in reality, a bloodthirsty sociopath who sees his children only as mere soldiers and weapons. While he initially loved Karen, he was by no means a loyal partner, abandoning her after the birth of their children. Although he initially appeared to care for them and wish to bond with them, this could be because he is reverting to his cruel, killer mindset, having grown up having to be tough, rather than explicitly trying to harm his children, as that is all he knows after so many years as an assassin. This is supported by the fact that he seemed annoyed when Mr. Puzzles offered to erase his memories of his family, as well as by the fact that he regretted what happened to his children and was still proud of them for what they learned from him, apologizing for his actions towards them and Karen.

WPNZ's defining characteristic is his incredibly violent and volatile behavior: he is prone to becoming aggressive, and when he does, he fights and seriously injures people, demonstrating genuine pleasure in inflicting pain on his enemies. He is very persistent and holds grudges against anyone who has wronged him, even going so far as to want to kill Mr. Puzzles for his betrayal three months later (which is ironic, since he told Puzzles in the car on the way to the fairgrounds to "leave the past behind"). He pursued Mr. Puzzles across multiple timelines in an attempt to eliminate him and even allied himself with former enemies that the SMG4 team had faced when they stood in his way, warning them that they would die with Puzzles if they continued to prevent him from eliminating him. He is shown to lose his temper easily and become enraged very quickly, swearing a great deal even by the series' standards. Furthermore, he is incredibly serious compared to most of the characters, and is completely astonished by the outlandish fighting styles of SMG4, SMG3, and Meggy. Since his fight with Karen, he suffers from episodes of emotional outbursts.

Despite his homicidal nature, he values ​​loyalty and friendship. He develops a close relationship with Toomp and Mr. Puzzles, treating the former with affection and respect, and offering sincere advice and support to the latter when he notices his stress. This stems from the time he spent with his children and the recurring memories of his fight with Karen and her children at Amazon headquarters, when he tried to train them to be killers like their mother.

Although he was upset that Karen had taken his children away, preventing him from being there for them, he eventually shows deep remorse for his actions toward his ex-partner and his children (which is later demonstrated when he asks SMG4 to deliver to Karen a note he wrote before sacrificing himself to seal the time rift along with Puzzles). He tries to be a better person and, between Mr. Puzzles, Toomp, and the others, he cares for them and strives not to repeat the same mistakes he made with his children.

This, coupled with his friendly attitude toward "Boxhead," demonstrates that he came to consider Puzzles a true friend. He was deeply hurt and furious upon discovering Puzzles' deception and betrayal, attempting to kill him while recalling all the plans they had shared as friends and the time they had spent together. This also highlights his aversion to being manipulated.
