Overview
Everything you need to know
The MK42 Right Arm is a 1:1 scale replica built for fans who value authenticity and advanced functionality. Modeled on Tony Stark's Mark 42 armor, it features motorized split-style panels that open and close on command, a light-up palm repulsor with blast effects, and a built-in laser cannon.
Just say "Jarvis" to wake the system, then control the arm with voice commands, the 5-button wireless remote, or the touch-sensitive palm button. Every action is paired with authentic sound effects, from the armor panels opening to the repulsor firing.
Built with an ABS shell and metallic finish, the arm is designed as a true 1:1 wearable piece with a comfortable fit for extended wear at conventions and events.
Ideal for Marvel and tech enthusiasts, collectors, cosplayers, or anyone seeking an authentic piece of the Mark 42 legacy.
High torque micro motors drive the armor panels open and closed, replicating the cinematic suit-up sequence seen on screen.
Say "Jarvis" to activate the system, then command the arm with English or Chinese voice commands.
Light-up palm cannon with explosion blast effects and sound. Press once for the flashlight, hold for 3 seconds to trigger the full repulsor blast.
A working laser activated by voice or remote, just like the real suit.
