Mr. Puzzles

is the manipulative, charismatic and psychopathic founder and CEO of the streaming service Puzzlevision who wishes to achieve complete perfection in his shows by brainwashing the whole world into being characters in it. Mr. Puzzles torments and manipulates the SMG4 Crew into several sadistic adventures to create content, and uses them as the main cast for his streaming service; causing the destruction of the Peach's Castle, the fall of Wren and mental torture and trauma of Meggy, and temporary betrayal of Mario. Ultimately, his constant failures to get his 5 Stars rating progressively worsen his treatment of his unwilling cast and break his friendly facade, culminating in him losing his temper and sanity by the time his ultimate plan comes into fruition.

Physically, Mr. Puzzles is a tall and thin black humanoid with a dark gray analog TV head, containing in its bottom edge the name "Puzzlevision". His real "face" is an off-white beige background with differently shaped eyes, and a large grin taking up most of his lower face; the mouth's colors are intended to resemble the TV color bars. He wears a black bowler hat on his head, with two TV antennas sticking out, though one is bent. He wears a light grey vest with a white undershirt and a black bow tie, as well as white gloves and black and white sneakers. His pants are dark grey, with silver puzzle patterns.

When as a pop-up, he was simply a TV similar to his head with cartoonish eyes and smile in it.

As a child, he was similar to Ness but totally black and with white eyes; he still had a normal human head back then.
