self-insert

/sɛlf ˈɪnsɜːrt/

Common

A character in fan fiction or creative writing who is a stand-in for the author, placed into an existing story world.

Self-inserts range from barely disguised wish fulfillment to legitimate autobiographical storytelling. The label is sometimes used dismissively, but the practice itself is a normal part of fan creativity.
