The trailer hints at a major showdown between Chris Hemsworth’s Thor and Doctor Doom, with fans drawing direct parallels to the hero's iconic charge against Thanos. Another seismic moment is the return of Chris Evans as Steve Rogers, who proves his worthiness by summoning Thor’s hammer. The reaction was immediate: "No way Thor testing to see if Steve was real or fake handing over the mijolnir HOLY PEAK," a user posted. While excitement is high, some fans noted a perceived lack of build-up for Doom, whose only prior MCU appearance is slated for The Fantastic Four: First Steps.
