Its about time Iron Man gets to have the ultimate upgrade – the EXTREMIS armor. Now Tony Stark doesn't have to cart around his armor in a suitcase. The extremis is bonded with his nervous system and so he can armor up at will. It also maks his body better than it ever has been. It helps him heal faster and virtually makes him man and machine in one, and more than usual. This arc sets up things to come and his Extremis armor will prove useful in later arcs in New Avengers. The story is great and the art is fabulous. If you never read Iron Man or never got into him this would be a great story to read.
