"C'mon kids... Pick ya' poison." Mr. WPNZ takes on a guardian-like role toward Cory, Katie, and Zack, but his version of parenting is twisted. He disguises questionable practices as games, such as gun training, in order to groom them to be assassins like their mother. While he might seem to care for them at times, he only ever truly cares about himself, (as Karen pointed it out) as he was shown to be manipulative with them when it came to participate in his missions, not to mention, he was more disappointed than actually afraid for his kids when one of them almost got killed in his heist at the Amazon headquarters. By the end of Silence Of The Cats, he is shown to see them as little more than extensions of himself, seeing as how he called them his "weapons". He is shown to be ruthless and reckless to successfully achieve his goals, as he turns innocent people like Mario into practice targets and injures Karen's allies to isolate her. Obsessed with her and her children, he stalks them relentlessly, forcing her to keep them hidden. His expertise in weaponry and mechanics makes him extremely dangerous, often requiring multiple people to take him down. Around others, Mr. WPNZ is shown to act as a charismatic, confident and sometimes kind person, which is all a facade to hide his true psychopathic nature, as he is in reality a sadistic and bloodthirsty assassin that enjoys murdering others and inflicting violence. While he might have had a genuinely loving relationship with Karen, it was clearly out of mutual sadism before the latter left him to raise her kids, as he only care about others if they are strong in his eyes. However, deep down, he does want to be a good father to his childrens and truly cares about them and his family, given how he seemed to be about to cry when they called him "dad" for the first time, and despite almost getting them killed all while berating them instead of trying to help them when he brought them along with him in his mission to Amazon's headquarters, he did grow to feel genuinely ashamed of that as shown when he yelled toward Toomp to "quit gawkin'", he remembered the exact time as to when he said that to his childrens with deep remorse. Additionally, after his final fight with Karen and his childrens, he reminisces his good moments with the laters several times, and while he accepted his deal with Mr. Puzzles to get his memories of them erased, he did so reluctantly, and in a moment where he opened up to him, he stated that "guys like us aren't supposed to have a family". Thus, while he is a sadistic assassin to the core, he isn't completely heartless and is able to show remorse.
