If the MCU decided to bring Tony Stark back, what would be the best way to do it?

What circumstance would it be brought back Tony Stark for a future Marvel movie?

Theory 1:

Bring him back as an AI.

With his holo-recording at the end of Endgame, it wouldn’t be too hard to explain that he actually managed to upload his consciousness onto a computer.

They showed that this is possible in the MCU. In Captain America, The Winter Soldier, Steve, and Natasha find that Zola (the Hydra scientist from the first Captain America film) was able to save his consciousness after he died and upload it onto a bunch of computers.

And that was done at least 40 years before Tony Stark died. I have no doubts that he would be able to figure that out. Maybe someone just needs to come across it and turn it on.

They could even go as far as to give him a new body similar to Vision, or perhaps it would be more fitting to just plug him into an Iron Man suit. He could become the next Jarvis.

It would be a cool concept but ultimately I think the way his story ended was the best way to do it.

Theory 2:

Well, how do we call Tony Stark, if he is, you know, dead?!

Let me tell you a little fact that I learned from Percy Jackson's books.

Thor is from greek/Norse mythology. And in Greek mythology, there is a city called Asgard. In Asgard, there is a hotel/hall thing (a type of afterlife), called “Valhalla”.

The only way you can get there is if you die in battle. Once you die in battle, your soul is transported to Valhalla, and that becomes your afterlife.

So Tony Stark survives! But there is a flaw. Asgard was destroyed.

So there is no Valhalla.

I think the best way the MCU could bring back Tony, is if the leftover Asgardians and Thor build a New Asgard, and Tony’s soul is transported there.

Even though Tony was killed by the Infinity Stones themselves, and there is NO reasonable way to do it,

I think it would still be great to see this happen.
