Spirit physiology: MX is an extremely powerful spirit, making him extraordinarily strong in terms of raw power and strength, allowing him to topple enemies and objects that stand in his path.
Enhanced jump: MX is shown to be able to leap at amazing heights, appearing capable of leaping from a seemingly bottomless pit back up to the surface.
Immortality: MX has existed since the beginning of the universe over 13 billion years ago, and thus, is immortal and beyond the possibility of dying from old age, as well as presumably outside sources such as being killed and he got infinite durability with it
Shapeshifting: MX can shapeshift between various forms and chose to take the form of Mario to lure in victims, albeit, heavily corrupted, large and monstrous. Despite this, he can also take a much less frightening form that better resembles Mario.
Mégethoskinesis: Excluding his shapeshifting from his faker to default forms, MX is able to change his size at will and is said to be able to grow to any size he wants and he is not only 12 feet
Soul transferal: MX can capture the souls of his victims and implement them into the game itself. By taking their souls and placing them in the game, he can put them in the vessels of characters, such as he did with Lucas by placing his soul in the body of Luigi.
Superhuman strength: MX is an absolute juggernaut and is capable of blasting his way through any and all forms of resistance, whether it be living or inanimate. He can effortlessly tear his way through tens of solid bricks without sustaining any wounds, as well as appearing seemingly unharmed after having jumped out of an apparent bottomless pit, but most likely he has infinite strength.
