Yes, Izuku Midoriya, also known as Deku, does lose his quirk, One For All, or at least the vast majority of its power, as he transfers it to others. This process leaves him with almost no power from the Quirk.
The Nature of One For All
One For All (OFA) is a unique transferable quirk that stockpiles power and can be passed down from user to user. It also contains the quirks of all its previous users, which Deku began to unlock and utilize during his time as the ninth wielder.
The Process of Quirk Loss
Deku's loss of One For All's power is a direct consequence of his actions during critical moments in the series. As he transfers the individual quirks stockpiled within One For All to others, the immense power tied to One For All gradually diminishes within him. This transfer mechanism is part of a desperate strategy to defeat a formidable adversary.
The reference indicates that:
- Progressive Loss: With each Quirk that was transferred, Deku experienced a corresponding reduction in the power associated with One For All.
- Near Depletion: This process continued until there was almost nothing left of One For All's power residing within him.
- Unexpected Outcome: The significant depletion of his power also facilitated a unique psychic link with his ultimate opponent, Shigaraki, through the connection of their quirks.
Implications for Deku
This profound loss of power marks a pivotal turning point for Deku. While it demonstrates his incredible self-sacrificial nature and strategic thinking, it fundamentally alters his capabilities and role moving forward. He transitions from being the overwhelming force of One For All to relying on whatever vestiges of power remain and his inherent ingenuity.
This development reshapes the dynamic of the final conflicts and emphasizes the themes of legacy, sacrifice, and the evolution of heroism beyond raw power.
