Loki’s return in the Avengers: Doomsday trailer has fans demanding a long-awaited reunion

The newly released Avengers: Doomsday trailer gave fans the first official look at Loki after months of speculation. Although his appearance in the trailer is brief, it has made fans think of the Thor-Loki reunion that they have longed for.

The trailer shows Loki standing inside a home, holding a TVA identification card, gazing out through a curtained window. That detail caught fans’ attention, with many believing it hints at Loki’s role in the upcoming multiversal conflict. Others quickly began hoping it would lead to a reunion with Thor.

Since Loki last made his appearance in Marvel’s Disney+ series, becoming the God of Stories and protector of the multiverse, his fate in the larger MCU timeline has remained largely uncertain. Many fans believe the TVA will have an important part to play in Doomsday. Others have begun speculating about his mission and how he could become involved in the battle against the deadly Dr. Doom.

Among all these theories, the reunion between Loki and Thor is far more emotional for fans. Fans can’t help but wonder how Thor would react to meeting his adopted brother after sharing some of the most memorable brotherly moments for many centuries in the MCU. They have seen them evolve from rivals to brothers, willing to sacrifice everything for each other.

The brothers last shared the screen in Avengers: Infinity War, where they last interacted before Thanos killed Loki. The character appearing in Doomsday is a variant whose journey continued in the Disney+ Loki series rather than the version killed by Thanos. Since Loki is now on a different path from the version Thor last knew, fans believe their reunion could become one of the film’s most emotional moments.

Whether Doomsday provides that special moment remains to be seen, but the online reaction shows just how much that reunion means to longtime Marvel fans. The trailer also teases the anticipated encounter between Thor and Chris Evans’s character, who greets him with one of Tony Stark’s signature lines before taking Mjolnir from Thor’s hands.

Avengers: Doomsday will release on December 18, 2026.
