The phrase “who does Egg grow up to be” is a bit too vague to answer with certainty, because there isn’t a single famous character simply called “Egg” whose adult identity is universally known in pop culture or news right now.

Here are the most likely things people might be asking about when they say this:

  • In anime or fiction discussions, “egg” is often used symbolically for a young or developing self that will “hatch” into a more mature or healed person, rather than into a specific named character. For example, analyses of shows like Wonder Egg Priority talk about eggs representing traumatized girls who are slowly learning to open up and “break out of their shell,” not literally growing up into some pre‑named person.
  • In classic mystery fiction, there is a character actually named Egg Lytton-Gore in Agatha Christie’s work; she doesn’t “grow up to be” someone else, she just matures and eventually ends up romantically with Oliver rather than the older actor she admires.

Because of that, there’s no single canon answer like “Egg grows up to be X,” and anyone online claiming a definitive identity is probably speaking metaphorically, joking, or referring to a very specific fandom in-joke or headcanon. If you meant a particular show, book, web series, or meme, share the name (for example: “In [series name] , who does Egg grow up to be?”), and I can narrow it down and walk through that character’s development or “future self” in more detail.
