Deku is Japanese in Origin.

Deku derives from Japanese deku (木偶), “wooden figure” or “puppet,” familiar from the phrase deku-no-bō meaning a “blockhead” or “dummy.” In modern media the name gained prominence through the anime/manga My Hero Academia, where protagonist Izuku Midoriya’s nickname “Deku” is reclaimed with a positive spin - echoing dekiru, “to be able,” it comes to suggest a can‑do attitude. Nintendo’s Legend of Zelda series also uses “Deku” for plant-like wooden beings, reinforcing the word’s wood/puppet imagery.

Usage as a given name remains rare in Japan but has emerged in English-speaking countries since the late 2010s as a fandom-inspired choice. Established variants are minimal; Deku is the standard romanization, with Izuku as a related formal alternative. The name is typically masculine in impression yet used unisex. Depending on context, meanings range from “wooden puppet; humble, simple person” to “capable; determined underdog.”
