We know that Iron Man takes a beating from Thanos in Avengers: Infinity War but it may be even worse than expected! We've known for a while now that Tony Stark will wind up with an arc reactor in both that movie and Avengers 4 but these new set photos provide our best look yet at the device.
As you can see, it appears to be alien in nature or at least far more advanced than past iterations.
Could it be that Iron Man uses alien tech to create a device which will keep him alive? A strange looking watch of sorts has also been spotted and it seems to have a countdown on it. Could that be how much time the hero has left before his heart will give out? That remains to be seen but it wouldn't be too surprising if Iron Man dies in Avengers 4 as Robert Downey Jr.'s tenure appears to be near its end.
