So,...Phase 4 came and went, and while I'd love to give a review of the whole, this is not the time or the place. Why we're here is instead to speculate on which characters may return from the Netflix, Hulu/Freeform and ABC shows, and where they might appear.
But before that, let's first give a couple of mentions as to how Marvel Studios connected with it's former television counterpart:
Agents of SHIELD had a few connections including the debut of Man-Thing, the appearance of Atlantis (renamed Talokan) and the return of the Darkhold
Anson Mount, Hayley At well, Dominic Cooper and Clark Gregg all reprised their respective roles as part of What If…? And Doctor Strange 2
But the biggest impact however is the one made by both Charlie Cox and Vincent D'Onofrio coming back in SM:NWH, She-Hulk and Hawkeye, with an 18 episode series to boot
Now onto the main stuff. While there are many characters who could return, just going project by project may be unproductive, so I instead think a list of characters is much better. So, I'll argue why and where we might see them. And no rumors, and just superheroes.
Luke Cage:Arguably the second highest rated show of the Netflix catalog, Luke has been the leader of the Avengers. As for where, the likeliest place is Daredevil: Born Again. Either that or maybe join Sam's new Avengers in NWO.
Nico Minoru: If Freshman Year is any indication, Marvel Studios has a liking for the character, plus Lyrica Okano just played her in Midnight Suns. The likeliest place is Agatha:Coven of Chaos right now, though Blade is my out of the box choice.
Punisher: Not only did he help Tom Holland audition for Spider-Man, but Jon Bernthal is a highlight of DD S2. So naturally, an appearance in Born Again is a guarantee, right? Or maybe a crossover in the next Spider-Man?
Colleen Wing: Jessica Henwick's star is on the rise and it would be a mistake not to have her back as the sword wielding badass. As to where, why not in Shang-Ch 2i? The actors already know each other. However the movie isn't part of this phase, so Born Again might do it.
Quake: AoS was the most viewed show for a time on Disney+ and I can't blame people for that. Daisy Johnson is a big reason I started watching it. While people have speculated her return on Secret Invasion, she could also be a part of either The Marvels or Cap 4. Time will tell. And get Yo-Yo in there too!
Ghost Rider (Reyes): Namor, Jack Russell and Marc Spector are all cool Latin American Representation, but there's one guy who did it first, and was originally brown from the start. After the cancellation of his series, Robbie deserves at least to be in either Coven of Chaos or Ironheart, just so he can fight demons this time.Or better yet, let him meet the Daywalker!
The Helstrom Siblings: To be honest, I just want a curveball prediction. Basically, having either spawn of "Satan" could be interesting in shows like Ironheart or Agatha:Coven of Chaos, though the first seems more likely given the Hood is a part of the show.
And that's all I got for now. Leave your ideas in the comments for other characters and where they could appear in Phase Five! Also, I'll do later a the Fox and SPUMC character appearances for Phase 5.
