 Though Zemo could still see through the eye holes of the hood, as well as hear, breathe, and speak through the thin fabric of the cloth that made up the hood, Zemo could no longer eat normally (due to the hood having no mouth hole) and had to be fed intravenously.Heinrich quickly recovered, but having his hood permanently attached to his face drove the Nazi scientist insane.Adopting a new costume to go along with his new hooded face, Zemo went from becoming a normal, if not infamous, Nazi scientist to become an active field agent for the Third Reich, leading German troops into combat and espionage missions.
