Warning: Spoilers for Miles Morales: Spider-Man #7!The best Iron Spider suit may not actually belong to the original Spider-Man, but his successor crafted by Iron Man for his most insane armor.
To help Miles deal with Cletus' most deadly form yet, Tony Stark s the battlefield in the final pages of Miles Morales: Spider-Man #7 by Cody Zigler, Federeico Vincentini, Bryan Valenza, and VC's Cory Petit. It is then that Tony watches Miles suffer a punctured lung, broken ribs, and multiple hemorrhages all in one killing blow from Cletus. To save him from dying, Iron Man gives him nanite clusters to speed up the recovery process and encases him in a "cast" that takes the form of a new Iron Spider suit designed for Miles.
Miles Morales Gets His Own Iron Spider Suit
The Iron Spider first appears in the comics during Amazing Spider-Man #529. In the days leading into the Civil War event, Tony Stark builds and gifts the Iron Spider suit to Peter Parker. When Peter asks what was wrong with the old suit, Tony answers, "Come on, Peter, it was just ... cloth." Back when Tony was grooming Peter to be his protégé, he felt that a more mechanized armor was more appropriate for him to use. This would later become a symbol of Peter's parable during the Civil War era, from his famous unmasking to Tony's pro-registration stance to his ultimate rebuff of his "mentor". Now, Tony offers the same gift to Miles Morales, albeit under different circumstances.
The first Iron Spider armor became a symbol of Iron Man at his worst, as a manipulative man who would stop at nothing to prove that he was right, and everyone else was wrong. Many fans blame Spider-Man's post-Civil War tragedies (Aunt May being shot and his consequent decision to make a deal with Mephisto to save her) on the fact that he trusted Tony Stark, which was proven to be ill-advised when Iron Man revealed he could take control of Peter's Iron Spider suit, track it, or shut it down at will.
Why Miles' Iron Spider is Better
Miles's Iron Spider armor appears in very different circumstances. It appears to save the young hero from sure death, and to let him help in the fight against Carnage. Thanks to Tony Stark, Miles is able to re-enter the battlefield basically recharged to 100% going into the next issue. While Peter's Iron Spider has certainly proved to be useful in its own right, it has never outright saved Peter's life. The circumstances in which Tony gives Miles the suit also speak of how Iron Man has changed from his Civil War days, making Miles Morales' Iron Spider suit overall better than Peter Parker's one.
Miles Morales: Spider-Man #7 is available now from Marvel Comics.
