After an initial appearance in 2007's What If Planet Hulk? #1, Skaar first appeared in canon Marvel continuity in 2008's World War Hulk #5. The son of the Hulk and the extraterrestrial shadow warrior Caiera, Skaar emerged from a cocoon on the remains of the destroyed planet Sakaar, where the events of World War Hulk had occurred, and he's had an eventful 17 years since his debut. In the MCU, however, little is known about him. His only appearance came in the ninth and final episode of 2022's She-Hulk: Attorney at Law, "Whose Show Is This?" Portrayed by Wil Deusner, he was introduced at a Walters family celebration but didn't say a word and hasn't reappeared since. It made fans wonder what Marvel Studios' plans for the character are in the Marvel Cinematic Universe.
