Liam Karlsson Confirmed as New Thor in Marvel's Animated Kids Series

Liam Karlsson is the new voice of Thor, according to a ScreenRant report on the animated kids series Iron Man and His Awesome Friends. The actor portrays a younger version of the God of Thunder in the show, which is currently airing on Disney Jr.

Karlsson's debut came in the episode 'The Mighty Thor and Mischievous Loki,' which launched with the second half of the show's first season. Nylan Parthipan joins the cast as the voice of Loki, with Alan Ruck voicing Odin.

Who else is in the cast?

The series features Mason Blomberg as Tony Stark/Iron Man, Kapri Ladd as Riri Williams/Ironheart, and Aidyn James Ahn as Amadeus Cho/Iron Hulk. Tony Hale voices Ultron, and Fred Tatasciore provides the voice for the team pet, Gamma, also known as Iron Pup. According to ScreenRant, the episode sees Thor and Loki team up with the Iron Friends, only for Loki to enchant their vehicles to act as his henchmen.

Is this Thor different from the MCU version?

Yes. The report describes Karlsson's Thor as a younger, brashly confident version of the character, distinct from Chris Hemsworth's portrayal in the Marvel Cinematic Universe. The character is depicted as a good friend to the Iron Friends and utilizes both a hi-tech armored form and a civilian appearance with a blond undercut.

Thor and Loki are set to recur throughout the remaining episodes of the season, with future installments titled 'Loki's Movie Mania,' 'Thor and the Frost Giant,' and 'Thor and Loki Hit the Road.'

What's next for this version of Thor?

Liam Karlsson is confirmed to reprise his role as Thor in the upcoming Disney Jr. series Avengers: Mightiest Friends, which is scheduled for release in 2027. The new show will feature kid-friendly versions of Captain America, Hulk, Black Widow, Iron Man, Spider-Man, and Thor. It is likely Nylan Parthipan will return as Loki.

Iron Man and His Awesome Friends is an animated series that first aired in August 2025. It is rated TV-Y and is available to stream on Disney Plus, fuboTV, YouTube TV, and DisneyNOW as of July 2026.
