Mr. WPNZ (pronounced as "Mister Weapons") Katphish is a major antagonist in Glitch Productions' SMG4 franchise. He is an assassin who has various weapons and technology as biological parts of himself, the former work partner and ex-husband of Katana "Karen" Katphish and is the father of Zack, Katie and Cory, who after years away from Karen’s life, finally wishes to “reconnect” with the family, ordering Mario to kidnap Karen’s three children so he can properly bond with them. However, said method of bonding proves incredibly reckless and psychotic, which reaches a breaking point upon him bringing the kids with him on a deadly mission. Following his defeat and divorce, he was approached by Mr. Puzzles, who was plotting to redeem himself in the eyes of the SMG4 crew and escape from prison due to both of them being criminals and having nothing left to lose. With the help of a blob named Toomp, they managed to break Mr. Puzzles out of jail and narrowly avoided escaping from The Death Cube. The two had formed a genuine friendship, but everything changed when Mr. Puzzles had WPNZ to kidnap someone. In a twist of betrayal, WPNZ became part of Mr. Puzzles' scheme to look like a hero, disregarding their friendship. Enraged with his treachery, WPNZ and Toomp confronted him, resulting in a fierce battle in which they ultimately overpowered him. Once the dust had settled, Mr. WPNZ reveals to Meggy and her friends that Mr. Puzzles was using them just like how he used him and Toomp and had tricked her into thinking he was a changed man. This revelation shattered Meggy’s faith in Puzzles upon seeing the criminal mastermind that he really is. WPNZ is ready to finish off Puzzles once and for all. Just then, the Death Cube arrives, sending Mr. Puzzles flying and forcing WPNZ and Toomp to make a quick escape. Afterwards, Toomp became WPNZ's new partner in crime. He (and Toomp) planned to eliminate Puzzles for good for his betrayal and kill everyone who has hurted him deeply, as Puzzles tries to change the past to erase the guilt and rewrite the mistakes he has made but went against the SMG4 crew too as they constantly got in his way of eliminating Puzzles. After a chase through time, the two manage to mend their friendship. In a selfless act, he chose to help Puzzles seal the anomaly rift as the latter banished himself (along with him) from the universe to protect reality, and as self remorse for their actions. He is Karen Katphish’s ex-husband turned (former) archenemy, the former second archenemy of SMG4, as well as Mr. Puzzles' former right-hand man and former enemy turned best friend. As of "Silence of the Cats" Trailer, he was revealed to be a rather bulky humanoid-cyborg almost resembling a shark with sharp, jagged teeth, yellow, triangular, cat-like eyes that become red when he's highly angered or when he feels any strong emotion, 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). He has feet that work like blasters that have singular black straps that go across with silver buckles and a singular strap for each leg (with some scratch marks on the boosters for the years he has had them), and metalic hands, with his left hand being the larger cuff and equipped with knuckle spikes, that can detatch itself and operate on its own, that can transform into various weapons, such as guns, chainsaws, and flamethrowers. His entire body is spiked with other miscellaneous armaments. He also wears a white shirt with a grey jacket with matching pants, a tie that looks like a knife, a pair of goggles resembling unused turrets, armored shoulder pads and leggings, along with robotic gloves with the left one being larger and has spiked knuckles that are potentially controlled via mind, remote control, someone via proxy or somehow can be controlled. His fingers have holes on the tips for where he can use to shoot his ammo. In Calling All Villains, his design remains mostly the same, but now with better graphics and a few tweaks. Notably, his left hand now has two pipes on both sides, his fingers now have visible joints and his barrel guns now have a canon at their centers. Mr. WPNZ does come off as a charismatic, confident and sometimes kind person. However, in truth, he is truly a short-tempered, sociopathic, ruthless, reckless, 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 cared about others if they are strong in his eyes. He wasn't really loyal as a partner with Karen either as he abandoned her after she had her three children, and he saw his children as soldiers and his "weapons". Initially, he appeared to show concern for his children and expressed a desire to connect with them. However, this may reflect a regression to his ingrained mentality as a merciless assassin, a role he has inhabited for many years. This notion is further corroborated by his visible distress when Mr. Puzzles proposed to eliminate his memories of his family, alongside his reflections on the events involving his children, for whom he still feels a sense of pride regarding the lessons they acquired from him. Additionally, he harbors remorse for his behavior towards Karen and his kids. He was shown to be manipulative with them when it came to participate in his missions, not to mention that he was shown to be 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" by trying to give them "Harsh Love" into becoming deadly assassins as himself to take pride onto them. He is is also very determined to succeed in his goals, as he turns innocent people like Mario into practice targets and injures Karen's allies to isolate her. Being 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. Mr. WPNZ takes on a guardian-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, in order to encourage them to become assassins like their mother used to be. He also was shown to be so obsessed to the point of constantly stalking Karen and her children to the point that Karen would have to try to keep her kids hidden. He is also shown to have a short temper (in which he could burst into a rage easily) and prone to becoming really aggressive, even to the point where he is very determined and refuses to stop until his enemies are defeated, even to where he almost succeeded in getting Mr. Puzzles killed for betraying him and teamed up with past enemies when SMG4 crew kept becoming an obstacle. Additionally, after his final fight with Karen and his children, he reminisces his good moments with them several times. While he accepted his deal with Mr. Puzzles to get his memories of them erased, he did so reluctantly. 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 has redeeming qualities. He does want to be a good father to his children and truly cares about them and his family deep down, given how he seemed to be about to cry when they called him “dad” for the first time. 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. This can be shown as when he yelled toward Toomp to “quit gawkin'”, he remembered the exact time as to when he said that to his children with deep remorse, even volunteering himself to take over the Job himself. He also hates being tricked and is against engineered heroics, as shown when Mr. Puzzles told the former to kidnap Meggy, only for Puzzles to later stop him just to make himself be seen as a hero, which angered him so much that their friendship temporarily ended. Given Mr. WPNZ's left arm is bigger than his right arm, along with the that, he primarily uses his left arm when fighting, it's likely Mr. WPNZ is left-handed.
