LOSSBOUT 12 · VS Orochi
Garou breaks free of Gyoro Gyoro's psychic hold and faces the Monster King Orochi, who copies Garou's stance and style on sight. Orochi overwhelms him and knocks him out.
FILING NOTE
Chapter 94 carries the fight through to Garou's defeat with no outside party stopping it, so it is a loss; the wiki's Episode 29 page lists Chapters 92 to 94 and its Garou/Battles table gives the fight as Chapter 94, Episode 29.
WINBOUT 01 · VS Garou
In the subterranean Monster Association headquarters, Orochi intercepts Garou after the Hero Hunter breaks Gyoro Gyoro's hold; Orochi copies Garou's Water Stream Rock Smashing Fist on sight with dragon-headed tendrils and pummels him into unconsciousness.
FILING NOTE
Files W because Orochi mimics Garou's martial arts style with his dragon tendrils and knocks him unconscious.
