Origin & Use
Tony build the Mark 4 to replace the damaged Mark 3 after his fight against Iron Monger (Obadiah Stane). Mark 4 is pretty much the same as Mark 3, except for a new look for the chest and the shoulder parts. That’s the armor Tony pee in for his birthday.
Just like the Mark 3, this armor is one of the most famous. Everybody knows about it which makes it a great suit for a party, Halloween or a cosplay event.
The only picture I found is available on the Marvel Wiki. It does not look like the movie version, specially with a nose in the middle of the face!
There are a few options if you’d like to suit up in the Mark 4.
