Iron Man Subterranean Armor
Iron Man uses his armor's morphing capability to adapt to any situation: aerial battles, deep sea rescue missions, even adventures in outer space. Sometimes, the golden avenger's exploits lead him far below the surface of the Earth--hence his Subterranean Armor! With this highly-protective suit of armor, he can burrow through solid rock, even bore through a mountain to incredible depths in search of the Mandarin's powerful rings.
