Professor Cuthbert Calculus is a fictional character in The Adventures of Tintin, the comics series by Belgian cartoonist Hergé. He is Tintin's friend, an absent-minded professor and half-deaf physicist, who invents many sophisticated devices used in the series, such as a one-person shark-shaped submarine, the Moon rocket, and an ultrasound weapon.

Merlin is a mythological figure prominently featured in the legend of King Arthur and best known as an enchanter or wizard. His usual depiction, based on an amalgamation of historical and legendary figures, was introduced by the 12th-century British author Geoffrey of Monmouth and the translator John of Cornwall. Geoffrey appears to have combined existing stories of Myrddin Wyllt, a North Brythonic prophet and madman with no connection to Arthur, with tales of the Romano-British war leader Ambrosius Aurelianus to form the composite figure called Merlinus Ambrosius . Geoffrey's rendering of the character became immediately popular, especially in Wales. Later writers in France and elsewhere expanded the account to produce a fuller image, creating one of the most important figures in the imagination and literature of the Middle Ages.

Morgan le Fay, alternatively known as Morgan[n]a, Morgain[a/e], Morg[a]ne, Morgant[e], Morge[i]n, and Morgue[in] among other names and spellings, is a powerful enchantress in the Arthurian legend. Early appearances of Morgan do not elaborate her character beyond her role as a goddess, a fay, a witch, or a sorceress, generally benevolent and related to King Arthur as his magical saviour and protector. Her prominence increased over time, as did her moral ambivalence, and in some texts there is an evolutionary transformation of her to an antagonist, particularly as portrayed in cyclical prose such as the Lancelot-Grail and the Post-Vulgate Cycle. A significant aspect in many of Morgan's medieval and later iterations is the unpredictable duality of her nature, with potential for both good and evil.
