Most of us are interested in all the Marvel shows arriving on Disney+ for the next couple of years, and they will mostly be about the second-tier characters who won't have a large role to play in Phase Four and beyond, so this would be a better alternative at storytelling.
Unfortunately that also leaves everything up to rumors, and this new MCUCosmic blog, derived from a "source" on 4chan, has premises for all the rumored shows (save for Rockey & Groot and Nick Fury)
First off; none of this is reliable, and should be taken with a grain of salt, while most of these shows are rumors or in early stages of development and will change over time.
*The Vision and Scarlet Witch will focus on them trying to settle down, but when Wanda tries to give Vision a soul, everything seems to go haywire. I personally don't like this as the basis for a show since it makes both characters feel redundent and I feel like Scarlet Witch has been made to mess up enough in the MCU. This gives word that Agatha Harkness might be the villain for the series, but I would rather prefer the Grim Reaper (Eric Williams), although making him separate from Simon Williams' connection to Vision from the comics, unless he's involved in the "creation a soul" part.
*Loki will focus on the young mischief maker during his upbringing on Asgard alongside a younger Odin and younger Thor. Tom Hiddelston will narrate the series instead of portraying the title character, though if this is true, then I would much prefer Loki's narration being physically seen and interacting with objects but not being part of the main story. The villains rumored for this show would be Karnilla and Ulik, so I guess a storyline involving the Norn Stones and the Nine Realms is what they're going for, but we all know what happened the last time Loki intervened in someone's quest to collect a set of stones - Snap!
*Hawkeye; this series has no confirmation from any noteworthy source as it was first rumored by Jeremy Conrad (MCUCosmic) himself, and the premise only follows suite in his own rumors of Kate Bishop playing a role, whom Conrad insisted was being played by Katherine Langford in Endgame, but that is also heavily unreliable. Trickshot is said to be the villain, but that seems to one-dimensional for the show and I would much rather prefer Taskmaster as a worthy antagonist who would really be able to challenge Clint, especially if he keeps his Ronin monikor after Endgame.
*Falcon/Winter Soldier; this one is referred to as Bucky & Falcon, so unreliable title to start off with, and will focus on Bucky Barnes and Sam Wilson teaming up with Sharon Carter and Nick Fury to take down a secret crime organization. Rumors fluttered earlier about the Serpent Society title tease for The Winter Soldier coming back as the new villains, but I had preferred this to be the case before that rumor went all over, and giving Fury and Carter more storylines after Endgame (especially how Sharon is being left out) would be the right move putting them in with Bucky and Sam.
*Lady Sif was rumored to be in development earlier last week by DiscussionFilm and will focus during her time banished from Asgard where she will team up with Beta Ray Bill (who will preferrably of left Sakaar by now) in their efforts to defeat Amora the Enchantress, the sister of Loreli who Sif fought back on Earth during Agents of S.H.I.E.L.D. A nice direction for the show would be to bring back Loreli and the premise also teases that Amora will have other villains by her side, but Skurge probably isn't one of them.
Now, none of these shows are confirmed and all of these storylines are simply rumors and speculation, but I thought it was noteworthy of getting them out there and my opinions as well. Overall, I think a majority of these sound interesting and I will be looking forward to whatever Disney+ offers for my favorite heroes. I'd like to know what any of you think about these rumors and you're opinions and speculation on the potential of these shows.
