Classic Loki was the MVP, so I hope he gets the figure treatment.
I know some collectors have experienced HT MCU fatigue, but the Disney+ shows are pumping out some great material. Though occasionally heavy handed (I'm looking at you, Act 3 of F&TWS), I'm finding the shows to be WAY more compelling than the majority of the films, and I enjoy the films immensely. The benefit of longer run times notwithstanding, I really dig how each show tackles a separate, interesting theme/conflict:
WandaVision -- the compartmentalization of grief/trauma
F&TWS -- the burden of iconography
Loki -- the inertia of a bad reputation
To me, the quality of the characters enhances the appeal of their shelf presence as figures, regardless of how cool their outfits may or may not be. Therefore, I hope HT goes hard on the Disney+ MCU franchises. The F&WS figure line NEEDS Zemo and Walker. The Loki line NEEDS at least one variation of Loki introduced in Episode 5 (other than Alligator Loki, which is low-hanging fruit). Even if these characters weren't visually appealing, which I think they absolutely are (Zemo in his mask was a long-awaited desire), each one of them contributes so much to the tone and greater world of their respective series, regardless of brief screen times in some cases. On that note, I'll never understand why people/companies think there's a correlation between a character's screen time and their appeal. Ledger's Joker doesn't actually appear in TDK that frequently at all, and yet he is incredibly consequential to the story, to say nothing of how enrapturing he is when we do see him. This extends to characters who die off, as well. Why would a character's death make that character any less desirable as a figure? Almost all of Tony Stark's suits can be said to have "died" as the saga advanced, considering that he never retrograded by using an outdated rig. Heck, this notion applies to any of the heroes' one-off outfits. Why then, shouldn't we get a figure of Vulture (who didn't even die)? Or of Peggy Carter? Or Heimdall?
By contrast, I find it a shame that HT (and audiences, for that matter) are infatuated with The Mandalorian, seeing as how the show's emotional appeal is so hollow, imo. And I'm a lifelong fan of the armor. Stripped of the fan service, all we're left with is a familiar trope that was done much better in films like "The Man from Nowhere" and "Leon the Professional." Yet the Mandalorian is the production line priority. *sigh* I dunno. I'm crossing my fingers for Sideshow's HT Marvel reveals this week, but if HT opts not to further flesh out the Disney+ MCU lines, I'll be a sad teddy bear.
