Mr. Puzzles

SMG4 is typically portrayed as either the only sane person in Peach's castle or a stereotypical meme-loving character. In his early appearances, SMG4 was constantly irritated by the shortcomings and stupid behavior of most of his friends; he disliked Mario's stupidity, Luigi's childishness, Toad's grouchiness, Steve's unpredictability, Peach Toadstool's bossiness, Fishy Boopkins's naivety, and Bob Bobowski's selfishness (for which, ironically, he is responsible). SMG4 was shown as one of the few sane members of the castle, usually as one of the smartest people in the room. In his early appearances as the "straight man," SMG4 was constantly the victim of the antics of the castle's inhabitants, as well as the madness and instability of the world around him. He seemed constantly pursued by rapists, serial killers, and psychopaths, as well as the police. He and Mario also often had to save the world from supervillains like SMG3 and occasionally Bowser, as well as destructive power gods like Ztar and Monster. However, when SMG4 wasn't causing all this chaos, he could usually be found in his room, making videos or looking at memes on his computer.

Up until the trial arc, SMG4 looked like any other SM64 machinist, practically identical to Mario, including his clothes. However, he wore a blue shirt and cap, as well as white overalls, but retained his signature white gloves and brown boots.

Smg4 is Mario's protector and closest ally, the de facto leader of his gang, and SMG3's former enemy. Passionate and protective of his cause, he seems to feign common sense, often irritated or shocked by Mario's stupidity and the madness of the world around him. Despite this, Mario and SMG4 are the two who founded their group of friends, which has grown over the years to include a diverse cast of characters who join the duo on numerous wild adventures and battles against powerful enemies in the storylines.

During SMG4's cosmological exploration, he began to ponder his origins, and after the invasion of a virus called "Zero" that haunted Mario, he began to uncover the truth about his past and his destiny as the Super Meme Guardian. Unfortunately, he was then forced to fight for his channel's existence against Nintendo in the "Trial" story arc, temporarily leading to the dissolution of his gang until Mario was able to rectify the situation. SMG4 was allowed to keep his channel on the condition that he use his original design going forward, and he deeply thanked Mario for saving everything and everyone.

Mr. Puzzles is a tall, television-shaped man. His head is a vintage 1970s CRT television with a few buttons and two dials. He also has a small black bowler hat with two antennas protruding from it: a straight right one and a curved left one, as well as the "Puzzlevision" logo at the bottom. He uses the television screen as his face, featuring multicolored eyes and six teeth colored yellow, cyan, green, pink, red, and blue, meant to mimic the SMPTE color bars.

He wears a white shirt with long, puffy sleeves and a gray vest, a black bow tie, black trousers with a puzzle-pattern, and suspenders with puzzle-pattern buttons. He also wears white gloves shaped like rubber hoses and black and white shoes.

Unlike his original appearance, he now wears a crimson bow tie, his vest is darker, and his facial expressions are more fluid and natural.

Mr. Puzzles is a powerful television entity who began as an ordinary man before replacing his head with a television, granting him a host of powerful but dangerous abilities related to television and an obsession with control. Childhood loneliness and the neglect of his "creative" dreams by his father and those around him fueled his obsession with media and a desire to gain fame and recognition through entertainment, ultimately leading him to found his own entertainment company and streaming platform, PUZZLEVISION.
His egocentric nature often extols his own achievements and prefers to work independently. Known for his insane perfectionism, he strives for flawless results in his plans and creations, believing them to be flawless and seeking as little interference from his colleagues as possible. He was the SMG4 team's longest-running adversary, triggering numerous chaotic events and committing various crimes in his relentless pursuit of his goals, the worst of which was inflicting severe post-traumatic stress disorder on Maggie.
