The Marvel Cinematic Universe has had a few brushes with the fantasy genre in its latest productions. From the Thor and Doctor Strange movies to the upcoming Agatha: Darkhold Diaries series, fantasy is becoming a popular accompanying genre in the MCU. However, there is one other character that can take the lore of fantasy and magic to the next level: Dane Whitman. Better known as the Black Knight, Dane Whitman was introduced in Eternals in 2021. Even though his future in the MCU is still uncertain, he has the potential to expand the lore of fantasy and magic in the MCU. He could do so by introducing new fantasy storylines, realms, and characters, such as Otherworld, Avalon and Excalibur.
