Devery Jacobs Reveals Whether There's Any Link Between WHAT IF...?'s Kahhori And Her ECHO Character

@ProfessorWhy - Thunderbird has been back for over a year now.

@ProfessorWhy - Usually when someone says to "bring back" a character, they had made an appearance prior. You can't fault me for assuming you meant the comics since Thunderbird has yet to make an MCU appearance.

@ProfessorWhy - also, he died, so ' bring back ' has multiple meanings.
In hindsight 😉

@SonOfAGif - Well that's one hell of a theory that hadn't occurred to me yet (also I haven't watched that episode yet), but it makes a LOT of sense, and if that's what Marvel has in plan as a way of "rebooting" the MCU at the conclusion of the Multiverse Saga then holy shitballs that would be a great way of not only doing so but also connecting the IS with the MS AND potentially giving some of the older characters a way to "retire" (for now anyway).

So with that in mind, let me add some potential candidates to your list for the remaining stones:

1. Power: Peter Quill. Makes sense. Do we really think that his story ends with him mopping floors at his local DQ (from the "What If...?" episode) for the rest of his life? Not likely. In fact, he may get bored with all that and decide to explore his Celestial side and in the process discovers that he has the powers of the Power stone after absorbing it at the end of "GotG Vol. 1".

2. Mind: Vision/Wanda (but mostly Vision). This could be what they are planning to do at the conclusion of the "Vision Quest" show. Being as Vision originally had the Mind stone literally in his forehead for quite a while he likely absorbed a great deal of its power, he just needs to rediscover that (seeing in ming that White Vision is still in old Vision's body). BUT, being as Wanda's (mutant) powers were originally unlocked by the Mind stone, she undoubtedly has some of that still in her as well, even though she's mainly the Power stone now, like you said. So maybe this impending Multiversal threat (the Beyonder) is the reason that Wanda is resurrected AND she needs to reunite with Vision to unlock his Mind stone power. Definitely checking off some lingering threads here.

3. Soul: Natasha/Gamora (v1)/Red Skull: Either of these would make sense as they've all be in contact with the Mind stone, and each would come with certain possible benefits: Natasha would be given a plausible reason for being resurrected allowing BW Natasha to continue (if wanted); same with Gamora which would allow her and Peter to have their proper "Happily ever after" send off (if wanted); and Red Skull could return him to Earth to plague whomever the Cap is. Plus, having a (former but still probably) villain as one of the needed avatars for the reformation of the MCU guarantees that for as "good" as it might be, there will undoubtedly still be some "evil" in the souls of some creatures as a result.

Anyhow, perhaps I put too much thought into all that, but what you suggested really started getting creative juices flowing about how this could be handled and how it could tie up some of the older characters' stories with them finale achieving their own "glorious purpose".

@StSteven - your ideas for Quill and Vision are really interesting. I like these.

@TheRose - I don't know. I feel like the color of the stone needs to align with the color of the character's energy signature. Soul for Adam makes sense, but Sentry's energy is usually yellow. Druig, maybe.
