Devils first appear in the first edition "Monster Manual" (1977), which includes the barbed devil (lesser devil), the bone devil (lesser devil), the erinyes (lesser devil), the horned devil (malebranche) (greater devil), the ice devil (greater devil), the lemure, the pit fiend (greater devil), and the arch-devils Asmodeus, Baalzebul, Dispater, and Geryon. The imp, a frequent servant of devils, also first appeared in the original "Monster Manual". The "Monster Manual" was reviewed by Don Turnbull in the British magazine "White Dwarf" #8 (August/September 1978). As part of his review, Turnbull comments on several new monsters introduced in the book, considering the devils the most prominent among them. Turnbull notes that "they are all pretty strong and compare not unfavourably in this respect with the Demons we already know".
