Personality
Through his “Mr. Ring-a-Ding” persona, Lux presents himself as a jovial, innocuous cartoon character with a knack for laughs. Before revealing his true nature to Belinda and the Doctor, Lux maintains an air of cordiality, gleefully introducing himself with a song and making polite conversation with the two afterwards. On occasion however, there are breaks in the persona where Lux’s true character is shown, such as when he talks about his desire for a physical body in the middle of his cartoon, when he demands for a man in the audience to repeat his quip, and when he alludes to his allegiance with the Pantheon of Discord by revealing that his laugh is the same as Toymaker’s.
In reality, Lux is conniving, manipulative, and at times sadistic. He is perfectly willing to utilize people’s personal struggles to his advantage, as demonstrated by him creating a replica of Reginald Pye’s wife to blackmail him into playing his projector. A crafty manipulator at heart, his cunning was capable of deceiving even the Doctor, as it was only when they talk with the fans in the false world where he and Belinda were able to find a way to break free from his tape. Though not to the extent of his peers in the Pantheon of Chaos, Lux notably has a bit of a sadistic streak, mocking the 15 people he imprisoned in film reels by claiming he “immortalized” them and cheerfully threatening to burn the replica of Pye’s wife when he tells the Doctor and Belinda to leave the theater.
Appearance
Utilizing a 1930s-era “rubberhose” cartoon character for an avatar, Lux has limber, noodle-esque limbs, big eyes with pie-shaped pupils and a comically wide grin. He has blue skin and a nose akin to that of a pig snout, which led Belinda to humorously question what was his design supposed to be of. He wears a white dress shirt with a buttoned vest and a black overcoat, purple overalls, yellow shoes, and a brown, stubby top hat. On top of his shirt lies a bright red bow tie.
