When Tony is in that suit, he is unstoppable, prideful hero. Troubles were sovled easily when he get on that suit. But without the powerful iron man suit, he is timid and dysphoric. I think he is kind of insecure, because he always rely on the suit. Imagine it, If you are in danger and you have a body guard. Later for some reason, the body guard have to left you. Will you feel insecure? I think the answer is “Yes”
Tony is a tough guy. The terrible things happened around him didn’t collapse him. He still believed that he can be a hero without that suit. He use some basic tools which he brought from the supermarket to make weapons. Without the suit, Tony become stronger and stronger. At least, he decided to remove his mechanical heart and destroy all his suits.
Iron man still play a important role in “The Avengers 2”, but I am curious about how Tony Stark can join the Avengers team without the suit.
