The new Avengers: Endgame scene featuring Tom Hiddleston’s Loki changes more than it probably should. The scene takes place during Steve Rogers and Peggy Carter’s final moment together, after Steve has returned the Infinity Stones and decides to stay in the past. Then Loki shows up at their door and offers his help. Suddenly, what used to be one of the quietest and most personal endings in Endgame is connected directly to whatever Marvel has planned for Avengers: Doomsday.
There’s also the small matter of which Loki we’re talking about here. He isn’t the same Loki who spent the Infinity Saga trying to conquer Earth, outsmart Thor, and generally make everyone’s life harder. His Disney+ series completely changed the character, eventually turning him into the person holding the timelines together. So if Avengers: Doomsday is really going to bring Tom Hiddleston’s Loki back into the middle of the MCU, it can’t just use him as a familiar face. This Loki has been through a lot, and he knows things about the multiverse that almost nobody else does.
A Direct Bridge From Endgame to Doomsday
What makes the new scene interesting is that it doesn’t feel like a normal extra scene added onto an old movie. It changes how we look at the ending of Endgame. Steve staying in the past with Peggy was always meant to be a personal choice, but now that moment can also be viewed as something with much bigger consequences for the timeline.
And Loki is probably the one person who would understand those consequences better than most. By the end of Loki Season 2, he has spent centuries dealing with timelines, branching realities and the TVA, eventually giving up his own freedom to keep the multiverse from falling apart. That’s a very different character from the one who walked into the first Avengers movie demanding to rule Earth.
That makes his appearance alongside Steve more than just a bit of nostalgia. It gives Marvel a way to connect the original Avengers era to the strange multiverse rules that have taken over the MCU. Whether that connection ends up being central to Doomsday or simply explains why Loki is involved again, the new scene has clearly given his return some extra weight.
Loki Is More Than a Trickster Now
One thing that can get overlooked when talking about Loki’s transformation is just how much he learned at the TVA. His growth wasn’t only emotional or moral. He also spent an enormous amount of time learning how the TVA worked, working with O.B. and getting a much deeper understanding of physics, mechanics and temporal engineering.
The old Loki was already clever, of course. He could manipulate people, use illusions and find a way out of situations where most characters would have been completely stuck. But his time with the TVA gave him an entirely different kind of knowledge. He now understands time and the multiverse almost as systems that can be studied and manipulated, rather than just something magical happening around him.
That could matter a lot in Doomsday. If Marvel is heading further into incursions, collapsing realities and different versions of characters crossing paths, Loki has something the other Avengers don’t. He doesn’t have to suddenly become the new Tony Stark or Bruce Banner, because that’s not really his role. But having someone around who understands what is happening to the multiverse could be incredibly useful when everything starts going wrong, which it probably will.
Doomsday Needs to Remember How Far Loki Has Come
The biggest problem with bringing Loki back is also pretty simple: Marvel can’t forget what happened to him in his own show. His entire story eventually led to one enormous choice. The character who spent years chasing power and control finally realized that saving everyone meant giving up the one thing he had always wanted for himself: freedom.
That sacrifice is what makes the Loki of Loki so different from the sarcastic troublemaker audiences remember from the Infinity Saga. Turning him back into the old version just because he can make a few funny comments would be an easy move, but it would also make his character development feel strangely pointless.
Instead, Doomsday has a chance to use Loki in a much more interesting way. He can be the person who understands the rules of the multiverse when everyone else is trying to figure them out as they go. His connection to Steve Rogers also gives Marvel a pretty natural way to tie the old MCU to the new one without simply throwing familiar characters into the story for the sake of it.
If the new Endgame scene is really meant to set up Loki’s return, then his role in Doomsday should feel like the next chapter of his story. He isn’t just the Loki audiences remember. He’s the guy sitting at the center of the multiverse, keeping countless timelines alive. That’s a much bigger role, and honestly, it would be a shame if Marvel treated it like anything less.
