The werewolf Waldemar Daninsky (known in Spain as "El Hombre Lobo") is without a doubt Paul Naschy's most famous horror character, since he played Daninsky in 12 different films.
Naschy's only other recurring character was the villainous medieval warlock Alaric de Marnac (who appeared in Naschy's Horror Rises from the Tomb (1972) and returned to life again in a sequel, Panic Beats (1982)).
