Richard Dragon, Kung-Fu Fighter #12

The cover by José Delbo and Vince Colletta sets up a genuinely unsettling premise: Richard Dragon, dressed in his red-and-yellow martial arts gear, is locked in fierce combat with an opponent who looks exactly like him — a mirror-image double in identical clothing reeling from a devastating strike. Onlookers in the background watch the confrontation unfold, and the tagline "A Kung-Fu Killer Battles His Deadliest Enemy… Himself!" makes the psychological stakes crystal clear. DC's 1976 martial-arts series was consistently delivering this kind of kinetic, high-concept action, and issue #12 — "A Dragon Defiant" — looks like a strong example of why the title earned its following.
