Yellow? I Assure you, he's Anything But

 Arms at his side, standing ever erect, the "yellow" M&M man stands vigilant, his piercing stare upon all. Sentinel of justice, he ferrets out the lies and deceit of today's society. His Sphere of Liberty, imbued with admantium, kevlar, and the ever so mystical transpari-steel, he is armed and willing to trod upon evil wherever it shall arise! Chest emblazoned with a heroic "M" for Masterful, Magnificent, and most of all Manly; lesser beings void their bowels with the sheer terror of his might! So you may rest easy tonight America, for that Mysterious Mister M fixes all with his piercing gaze, and while he is yellow; I can assure you that he is no coward!
