There are 6 possibilites-
Edit: no self promotion
Then why promote here if you want Iron Man come back?
Stupid answer, Iron Man cannot travel back in time after he died.
@GiantCatbass well the team can go back in time take him from that exact moment bring him to the future and than when he starting to look a bit older send him back in time
Doctor Doom's Time Machine
Have research on time traveling
If they want to bring him back in Earth-616.
Lazarus Pits are from DC and I assume your talking about MCU so no he isn't coming back, Riri might join the MCU as Ironheart but Tony isn't coming back. In the comics he will probably live on after Iron Man 2020 as an AI still
@GiantCatbass they can go into the quantum realm
@Batpig 10101 are you talking about MCU Tony or 616 Tony
@ramocisco mcu tony stark why
Wait. Did Stark die again in the comics?
I suppose that's why there is an Iron Man 2020 up and running...
What do you think?
