Mr. WPNZ takes on the father-like role toward Cory, Katie, and Zack, but his version of parenting is twisted and extreme. He disguises questionable practices as games, such as gun training, encouraging them to be assassins like their mother back in the day in order for them to be strong just like him and their mother when they were assassins. He is shown to be ruthless and reckless to successfully achieve his goals, he turns innocent people like Mario into practice targets and injures Karen's allies to isolate her. Obsessed with Karen and her children, he stalks them relentlessly, forcing her to keep them hidden. His expertise in weaponry and mechanics and his very aggressive behavior makes him extremely dangerous, often requiring multiple people to take him down. Mr. WPNZ in truth, is a bloodthirsty sociopath who only sees his children as mere weaponized soldiers and weapons. While he originally loved Karen, he was by no means a loyal partner to her, abandoning her after her children were born. Although he did seem to care about his kids at first and wanted to bond with them so this might be more of him going back into his normal established cruel mindset of an assassin and growing up having to be tough rather than trying to explicitly hurt his kids because that is all he knows with all the years he’s been an assassin. This is supported by the fact he seemed genuinely upset when Mr. Puzzles offered to erase his memories of his family. As well as him lamenting what happened with his kids and still being proud of them for what they learned through him and regretting his actions toward them and Karen. Despite his homicidal personality, he still values loyalty and friendship. He bonds with Toomp and Mr. Puzzles, treating the former with care and respect while offering genuine advice and support to the latter when noticing his stress. This alongside his friendly attitude towards "Boxhead" shows that he came to view Puzzles as a genuine friend. He was truly hurt and furious when realizing Puzzles' deceit and betrayal, trying to kill him while reminiscing all the plans they had as friends and the time they spent together. "Oh. Hi..I'm Mr wpnz."
