One of the inciting incidents in Marvel's Civil War II event was James "War Machine" Rhodes' death at the hands of the Mad Titan Thanos. The loss of Rhodes split Iron Man and Captain Marvel down a philosophical line, with Carol Danvers in favor of predictive judgment before a crime is committed, and Tony Stark heavily against it.
Before Brian Michael Bendis departs Marvel for DC Comics in an exclusive agreement, the writer looks to be setting events in motion that will culminate in War Machine's revival in a preview of Invincible Iron Man #600.
After having a near-death experience of his own in Civil War II, Tony was able to save his own life, thanks to the many modifications he'd made to his DNA over the years. Of course, this gets Tony thinking: If he was able to bring himself back from the dead, can he do the same for Rhodey? Which then begs the question of should he? Is this something Rhodey would even be comfortable with?
Invincible Iron Man #600 isn't the only time War Machine's return has been mentioned recently. The title will be relaunched by writer Dan Slott and artist Valerio Schiti in Tony Stark: Iron Man for Marvel's "Fresh Start," and the solicitation text for Issue #2 also teases the possibility of Rhodey returning to life.
Bendis has big things planned for his final Marvel comic (for now). Along with the return of a forgotten X-Men character, the writer also promised one more major creation before heading to DC. Could this creation be a new identity for James Rhodes? If Tony winds up tinkering with Rhodey's remains to bring him back to life, the result could be an entirely new War Machine.
Invincible Iron Man #600 goes on sale May 23 from Marvel Comics.
