They’re your parents

Mr Puzzles is a TV head man with a tall body. His head is a vintage CRT TV from the 70s, which has some buttons and two knobs. He also has a small black bowler hat with two antennae sticking out of it; a straight right antenna and a bent left antenna, and a "Puzzlevision" logo at the bottom framing. He uses the screen as his face, in which his face has mismatching eyes and six teeth individually colored as yellow, cyan, green, pink, red, and blue, which is intended to resemble the SMPTE color bars. He wears a white shirt with long puffy sleeves and a gray vest, black bowtie, black pants with puzzle patterns on them which comes along with suspenders with puzzle buttons. He also wears white rubberhose-styled gloves and black and white shoes. Unlike his original look, he now wears a magenta bowtie, his vest is now darker in color

Mr. WPNZ is a rather tall and bulky humanoid cyborg with a shark-like appearance, though it is never specified what his species is. He has silver skin, sharp jagged teeth, has thick, black eyebrows, and yellow triangular eyes that can turn red white pupils when he is enraged or feeling strong emotions, such as sadism. His pupils resemble pointed-ovals, that can widen when deeply emotional in a positive way or very sad (like when he did that after Katie called him "dad", or after realizing and feeling bad about how he told his kids to "stop gawking" when he said that exact line to Toomp). His upper eyelids are dark gray, while his lower eyelids are dark blue, and he bears an X-shaped scar on his forehead. His feet are notably bulky and modelled after jet-powered blasters, each secured by a single black belt. His hands are asymmetrical, with his left arm being larger than his right but also detachable. His fingers have holes on the tips for where he can use them to shoot. His left hand also has a melded-in piece attached on the back of his hand thats somewhat resembles brass knuckles. On the back of his jacket has a vent-like piece.

For clothing, he wears a white shirt beneath a gray jacket featuring horizontal stripes at the hem with a gray patch on the back. His right sleeve has yellow and blue bands encircling it, while the jacket itself is adorned with metal plates, some shaped like turrets, and several belts. The jacket's teeth are gray, jagged with a collar, fitted with bolt-like details. The bottom section consists of matching pants, including a light blue patch on the right leg, a light blue belt on the left leg, and a gray belt. He also wears a knife around his neck in the place of a tie, a pair of goggles resembling unused turrets, armored shoulder pads and leggings, and robotic gloves.

Mr. Puzzles had a long complicated history with SMG4, he is depicted as a flamboyant and unstable sociopath fixated on fame and validation, often using manipulation and psychological abuse to further his entertainment goals while disregarding the traumatic pain he inflicts on others. His obsession with achieving "5-star ratings" reduces people to mere tools, and his insecurity leads to violent outbursts when things don't go his way. Rooted in a lonely childhood marked by a neglectful father and a lack of true friendships, his addiction to television serves as an escape, culminating in a act of self-mutilation where he replaces his own head with a TV set. After facing numerous setbacks and time in prison, Mr. Puzzles begins to recognize that his fame obsession conceals a deeper desire for friendship. However, his neurotic and manipulative nature obstructs genuine connections, causing him to betray those who care for him, and become not only both a stigmatized disgrace and public enemy number 1 to the Mushroom Kingdom, but also being the definition of a menace to society and the best of a bad situation, as well as becoming the worst human being known to the SMG4verse. Feeling genuine remorse for his actions and a desperate need to make amends, he attempts to rewrite his past, though others perceive this as evasion of emotional responsibility. Ultimately, his journey reveals the necessity of confronting his past misdeeds rather than trying to erase them, as this realization is crucial for alleviating his guilt and trying to improve the show, he decided to finally abandon his life long pursuit of fame and creative vision, then banish himself for every trauma he has inflicted.

He is shown to be ruthless and reckless to successfully achieve 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 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, sociopathic individual 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 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.[1]

What stands WPNZ out from other villains in the series is his super serious demeanor and how prone he to becoming incredibly violent and short-tempered and really aggressive. He will fight and seriously injure people when he does so, and displays actual enjoyment in bringing pain to his enemies. He is very persistent and also shows to hold grudges against anyone who has wronged him due to him wanting to kill Mr. Puzzles for his betrayal 3 months after it happened (which is ironic due to him telling Puzzles in the car ride to the Showgrounds to "let go of the past."). He would chase Mr. Puzzles to multiple timelines to try to eliminate him and even teamed up with past enemies that the SMG4 crew has faced when they consistently got in his way saying that they will go down with Puzzles if they were gonna keep preventing him from eliminating him. He is shown to easily lose his temper and burst into rage very easily too, cursing a lot even for the show's standard, also being incredibly serious when compared to most characters in the series, being completely in shock by SMG4, SMG3 and Meggy's wacky fighting styles. Since after the fight he had against Karen, he has episodes of emotional flooding.

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 comes from his time he spent with his children and the reoccurring flashbacks of his fight with Karen and his children at the Amazon Headquarters when he tries to turn his kids into assassins like their mother.

Although he was upset that Karen took his kids away from him which ceased his opportunity to be there for his children, he ultimately shows deep levels of regret in his actions to his former partner and his children (which would be shown later on when he asks SMG4 to give Karen a note he wrote before he sacrifices himself to seal the time rift along with Puzzles.) and tries to be a better person and among Mr. Puzzles, Toomp, and others, he cares about and to not makes the same mistakes as he did with his children.

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. This also shows his hate of being played.
