Mr. Puzzles

He serves as the overarching and true antagonist of Season 13 and the main antagonist of Season 14 onwards, appearing as the overarching antagonist of the Puzzlevision story and the main antagonist of most of the arcs related to it.

Physically, Mr. Puzzles is a tall and thin humanoid, with a gray 50s/60s television box head that is identical to his adware form, minus the face. His real face is a light gray static background with differently shaped eyes with one big and one small, along with a large grin taking up most of his lower face. His teeth's colors, which are yellow, cyan, lime green, pink, red, and blue, are intended to resemble a TV ‘s color bars. Although his face is depicted as a screen, it is implied that his face is actually behind it as it remains intact even after the screen is shattered by Mario. The bottom edge of his head has the word "Puzzlevision" printed on it, which is an entertainment streaming service platform that he owns. He also seems to have a black cable-like neck that connects to the back of his TV head, which bares similarity to what actual cables do with TVs. He wears a black bowler hat with a gray band on his head, with two TV antennas sticking out, though one is bent. He wears a grey vest with a white undershirt and a black bow tie, as well as white elongated four fingered rubber hose gloves and black and white dress sneakers. His pants are dark grey, with silver puzzle patterns, his pants also come with suspenders with grey puzzle pieces as buttons. His pants are also a tad bit short and thin black cable-like legs are visible if one looks closer. One of his eyebrows also forms a lightning bolt. He cycles through different faces that appear on his screen, using the same colored smile and grey eyes. However, when he has an insanity rush, his face goes into a creepy face without the smile, nicknamed Photoshop Mr. Puzzles or just the Insane face.

Mr. Puzzles maintains a complex personality rooted in a strong ego and an expectancy for control. He often craves attention, evident from the name of his entertainment company, "Puzzlevision," and his persistent desire to be in the spotlight. He manipulates those around him, including the SMG4 crew, making them obsess over their objectives, and turning them into adversaries for his twisted shows. Despite his friendly façade, Mr. Puzzles has unstable mental tendencies and sociopathic traits, demonstrating a troubling lack of empathy and a talent for exploiting others for his benefit. For instance, he showed enjoyment in seeing Meggy mistreated by Oneshot Wren and took delight in SMG4's ability to "play an antagonist so well." His unstable mentality can make him have severe breakdowns when something keeps going wrong, and his temper reflects it as seen in Mr. Puzzles' Incredible Game Show Spectacular!

His dedication to entertainment is so compulsive, that he has transformed into a cyborg with a television set-like appearance, and once he took over Didneyland and replaced it with Puzzle Park, he fused with the engine room of his new amusement park, becoming its power source, all of this symbolizing his obsessive nature. Even though he possesses ruthless ambition and a craving for control over his entertainment platform, Mr. Puzzles is still able to be affable if he wants to, as evidenced by his temporary bond with Leggy. He experiences deep emotional distress when she is taken away, revealing his underlying vulnerability and bit of humanity.
