Since my youth, I've been playing a SNES game called Marvel Super Heroes In War of the Gems, which is basically an "Avengers" game where you have to fight some Marvel villains to retrieve the 6 Infinity Gems.
One of the 5 playable characters is Iron Man.
Though I've never noticed it before, lately, something started bothering me whenever I replay it.
Unlike the armour he's seen wearing in some modern works (Avengers: Earth's Mightiest Heroes, Avengers: Assemble, or the Avengers movies), we could actually see muscle lines, as well as his breathing pace (see this short recording).
Either the armour is made of some material that can take the shape of its user, or it's not made of metal at all (which wouldn't protect him).
I tried to search up for anything that looks like that one. While I was able to find multiple armours with a triangle in the middle as well as muscle lines, the closest I could find to the one depicted in the game is Model 20 armour from Earh-616. But the drawings suggest that it's made of hard metal (which wouldn't be able to display the breathing pace).
