persona 

Social Media Influencers:
Many influencers present a carefully crafted persona — always happy, adventurous, or ultra-productive — even if their private life is much more complicated.
Example: A "travel blogger" might adopt a persona of a free-spirited adventurer, even if they are highly anxious in real life.

Corporate Spokespeople:
When CEOs post statements, they often adopt a formal, trustworthy persona, even if they are personally very casual or blunt in private.
Example: Tim Cook (Apple CEO) often presents a calm, composed persona representing Apple's brand values, regardless of personal mood or private opinions.

Musicians and Performers:
Artists often create a stage persona that’s exaggerated or different from their real selves.
Example: Lady Gaga’s early career persona was theatrical, outrageous, and avant-garde, even though she is known to be relatively reserved offstage.

Authors Writing in Character:
Some authors write in a persona that isn't their own voice.
Example: In The Catcher in the Rye, J.D. Salinger creates the persona of Holden Caulfield — a cynical teenage narrator — though Salinger himself was an adult man.

Politicians Campaigning:
Politicians often adopt a "man/woman of the people" persona during election seasons, portraying themselves as relatable and empathetic to voters' everyday lives.
Example: A millionaire candidate might wear jeans and eat at diners to craft a down-to-earth persona.
