Why does Tony Stark activate his suit with just a touch?
Why does the Iron Man suit only activate after touching the nanodevice? An interesting detail in the Marvel films is that Tony Stark always touches the nanodevice on his chest to activate his nanosuit. However, other heroes use more automatic activation systems. A possible explanation may lie in Iron Man 3, where Tony's armor once activated automatically during an anxiety attack and nearly attacked Pepper Potts. Afterward, Tony may have deliberately left the activation on manual mode so that the suit never activates automatically. An interesting detail and theory from the Marvel Cinematic Universe.
