The Loki is a series that will be jumping straight from Phase One, as it takes a look at the titular character from The Avengers in an alternate timeline.
Due to this unique premise, there can be several characters that haven’t been seen in the MCU for years or at all who have a chance to appear in this series. These are the ones who have interacted with Loki before in the MCU, as well as those that are currently exclusive to the comics.
Thor
While Loki himself is the , nobody wants the Loki series to go by without bringing Thor back as well. These two siblings have been connected to each other for over a thousand years in-universe and a decade in MCU film releases.
This version of Loki was never taken back to Asgard by Thor, meaning Loki can still harbor beef against his brother for their clash in the Battle of New York. Thor can show up looking to take Loki back to Asgard as part of his plotline.
Thanos
The fear factor of Thanos has subsided somewhat thanks to the many memes at his expense since the release of Avengers: Endgame. Let’s not forget that it was the Mad Titan who killed the original Loki, though, along with the fact that the TV series Loki has made off with the Space Stone, the very thing Thanos desires.
There’s a very easy way to incorporate him in the story, seeing as Thanos’ influence is supposed to be all around the universe. The Loki series can show the titular character trying to escape Thanos’ grasp as the latter tries to capture him and the Space stone.
Midgard Serpent
While Thor: Ragnarok did many things right to revitalize the trilogy, it didn’t bring the Midgard Serpent in the plot. Ragnarok’s arrival is supposed to be tied to this creature, which is supposed to the son of Loki. While a familial link would be a stretch for the MCU, the Serpent can still appear on his own.
After all, the series changed Hela from being the daughter of Loki to his elder sister, so there’s nothing stopping the Serpent from being something else as well. In the comics, the evil King Loki had used the Midgard Serpent to attack Asgard, which the MCU can adapt around to make Loki’s use of the Serpent vary.
Absorbing Man
Absorbing Man happens to be one of the villains fans want to see in Phase Four, although it’s worth mentioning that he did appear in the MCU in Agents of S.H.I.E.L.D. That version can easily be retconned since Loki’s continuity is back in 2012.
In the comics, Absorbing Man got his powers due to drinking a potion that was laced with poison by none other than Loki. Since the TV series version of the character is still a villain, it’s understandable why he would pull a similar move, especially since Absorbing Man turns out to be a baddie.
Laufey
Most don’t realize how the Frost Giants had an inadvertently . Laufey was the father of Loki and abandoned the baby to die until Odin rescued him. While Laufey had perished by The Avengers, the Loki series is so deep into magic and illusions that his return is possible.
Loki claimed he was the rightful king of Jötunheimr, and it would make for an interesting scene to watch him and his real father have a true interaction. The comic book Laufey went so far as to eat Loki whole, a kind of savagery that can be incorporated in the MCU, just without the part where Loki perished.
Lady Sif
The MCU versions of Loki and Sif have had something of a rivalry, but it’s their comic book counterparts that have had an intriguing backstory. For a while, Loki had possessed Sif’s body, transferring her conscience elsewhere.
He can do the same in the Loki series as well, which would be a good way to progress the antagonism between these two characters. With the Thor: Love and Thunder, the alternate one can have Loki as the character to be associated with.
Sigyn
Not many are aware of Sigyn’s status as the wife of Loki, and the character can be used in the TV series to set her up as his first love interest. Her fate in the comics was awful, as Loki abandoned her despite earlier having killed her fiance so she’d marry him.
The character still has potential and this can be best adapted by bringing forward the same character but focusing more on her strengths. The chance to see Loki in love is welcome, as he’s never before been shown to be romantically interested in anyone.
Tyr
Tyr appeared in the MCU previously, but it was in a minor role with no bearing to the plot as he was seen alongside Odin. Loki can expand on this by showing the trickster turn away from Odin as he did in the comics as a way to plan his revenge on his father.
The comics then showed Loki betraying Tyr as well, which aligns with the way the MCU character works. There can be a revisit to the angle of Loki overthrowing his father, this time with the help of Tyr.
Jane Foster
Loki and Jane didn’t have much to do with one another other than Jane lashing out at him for causing the Battle of New York. Loki is aware of the romance between her and Thor, though, making Jane one of his prospective targets.
Since this Loki hasn’t undergone the events of Thor: The Dark World, he has no reason to believe in Thor’s love for her, so it makes sense for Loki to go after Jane in order to antagonize Thor further. Being a scientist, Jane would also be useful for Loki to understand how space works.
Frigga
Considering how she loved a megalomaniac like Loki unconditionally, there’s no doubt that Frigga is the best parent in the MCU. She was the only one who could ever talk sense into him, along with being the one person whom Loki actually warmed up to completely.
It would be strange for Loki to be free and not attempt to his mother in any way, especially since he has the Tesseract to instantly reach her whenever he wants. A scene with Frigga and Loki which emulates the sentiment she had with Thor in Avengers: Endgame sounds like the perfect set-up.
