Hawks got sent to the hospital even before the war was finished.He was talking to Endeavor..if you can call what he's doing talking.He can barely even breath.Madam president waits until Endeavor leaves back to his room before entering Hawks's room with her helpers. "The Doctors told us that you are unable to recover your wings.We are sure you know what that means." Hawks looks at them for a morning before nodding and quietly answering* "yeah..." He looks away and out the window..As madam president motions for her helpers to pull the pluck.. "Thanks for your service,Hawks." Madam president finally says.Hawks just looks out the window and speaks to himself "..keigo...my..name..is..Keigo Takami.." He didn't want to die as Hawks.the person they made him.Madam president had already left as he lays there dying as he looks out the window.Basically all the Heroes who fought in the war are here in the hospital..he knew everyone would soon know about his passing.
