This Loki will be the one from 2012’s Avengers who escaped with the Tesseract in “Endgame”.
Fans has been excited for quite some time on what Tom Hiddleston does with his very own Loki-centric Disney+ show since it was announced last year, and now the actor has provided a first look of the behind the scene actions going on.
On Instagram, Hiddleston shared a short clip of what appears to be rehearsal for a scene in "Loki", where the actor is all wired up in order to make a godlike jump . Thor's scheming brother, long the MCU's most popular villain, turned into an antihero and sometimes-hero in the course of "The Dark World", "Ragnarok", and "Infinity War", where he essentially sacrificed himself to save Thor and try to stop Thanos.
"The Loki" of the Loki series is not the Loki we came to see developed onscreen—not exactly. This Loki will be the one from 2012's Avengers who escaped with the Tesseract in "Endgame". Which means we can expect that much of the character growth
Loki made in recent years is erased—but we also know now that Loki is capable of being more than the bad guy, and hopefully he's on a journey to discover the same.
Marvel took pains to establish that Loki had been somewhat under the influence of Thanos' scepter during the events of Avengers, then never addressed this in the movies. It could still become a plot element here at some point, as Loki deals with the fact that he was manipulated by Thanos.
Younger versions of Loki, which have found success in comic runs, are rumoured to possibly join the MCU considering the Young Avengers initiative on Disney+, though that Loki would likely be older in appearance. Fans are also hoping that Loki might see the introduction of Lady Loki, another popular incarnation of the ever-shifting character.
British actress Sophia Di Martino has been cast in an unknown role on "The Loki", with speculation that she could be playing Lady Loki or the opportunistic enchantress Amora, a Loki friend and foil.
