Mario (voiced by Chris Pratt) is the titular protagonist of The Super Mario Bros. Movie.
Mario's appearance resembles his video game counterpart but far more detailed. He now wears a red collared shirt rather than the basic red tee his video game version dons, his shoes now have laces, and his overalls now have a pocket on the front. Mario is shown to be friendly, as even when it was his first time visiting the Mushroom Kingdom, he did not hesitate to give a Coin back to a Toad who dropped it or greet the Toads.
He cares a lot about Luigi, as he gets annoyed when people talk lowly about him, and he does not take kindly to those who are rude to him. He is shown to be confident in himself, sometimes too much, to the point of thinking he can handle a challenge despite having no idea how to, resulting in him getting himself injured in the process. Ironically, he has a distaste for mushrooms, as shown by him picking them off his pasta in disgust and refusing to eat a Super Mushroom.
Mario is also shown to be very protective of Luigi and will fiercely defend him from anyone who bullies him. Some examples of this include Mario protecting Luigi from a bully during their youth and standing up to Spike, who insulted Luigi.
For the whole movie, Mario speaks in a (faint) Brooklyn accent, much like his counterparts from both the Super Mario Bros. Super Show and the 1993 Super Mario Bros. live-action film, respectively. Although, in the film’s opening, he does briefly speak in a very similar Italian accent, much like his video game counterpart, for the in-universe commercial about of his and Luigi's company, Super Mario Bros. Plumbing.
