This trope is also known as Illeism, which is the act of referring to oneself in the third person. This trope has a long history in literature, from historical works such as Xenobas' Anabasis, Shakespeare's Julius Caesar, and Mary Shelley's Frankenstein.
CAESAR: Caesar shall go forth Julius Caesar, Act 2, Scene 2)
The word is derived from the Latin third person pronoun 'ille' which means 'he' or that'; it is often used to create a sense of formality or detachment. In modern use, however, it can have a humorous effect: illeism can denote a lack of awareness or superciliousness.
