The Mark 42 is one of billionaire Tony Stark’s many Iron Man armors and is possibly one of the coolest ones he’s ever built! Featured in Iron Man 3, the Mark 42 is known for being able to find Tony wherever he might be, fly to him in pieces, and fit back together around his body. Your little boy can become this armored Avenger this Halloween with the Boy’s Iron Man Mark 42 Classic Costume! This jumpsuit is printed with the primarily gold armor with hot rod red accents. The plastic helmet almost looks functional with his gold-colored faceplate and slitted eyes. Your son will feel so much like Iron Man in this costume that he might even be compelled to build a lab in the basement and hire his own personal assistant!
