IPA: /ˈʌpˌsteɪdʒər/

A person, often an actor, who tries to attract attention to themselves, often at the expense of others, especially in a performance or social situation.
During the play, she became the upstager, drawing all the audience's attention away from her fellow actors.
Upstager → It is formed from "up" (meaning higher or above) and "stage" (from Old French *estage*, meaning a platform or stage for performances). The word "upstager" refers to someone who draws attention away from the main performer, often by being more prominent or noticeable on the stage.
Think of someone who is 'higher' ('up') in attention than the main performer on the 'stage' — that's why an upstager takes the spotlight away.
