Contessa Valentina Allegra de la Fontaine is a fictional, comic book espionage agent in the Marvel Comics universe. Created by writer-artist Jim Steranko, she first appeared in the "Nick Fury, Agent of S.H.I.E.L.D." feature in Strange Tales #159 (Aug 1967).
An agent who literally threw S.H.I.E.L.D. chief Nick Fury for a loop upon their initial meeting, she quickly became his love interest, and was featured in a silent, one-page seduction sequence in Nick Fury, Agent of S.H.I.E.L.D. #2 that famously had two panels changed, at the behest of the Comics Code Authority. In the third-to-last panel, de facto Marvel art director John Romita Sr. redrew a telephone that had been taken off the hook for privacy, placing the receiver back in the cradle; in the last panel, an image was removed and replaced with a closeup of an item from earlier in the page — a phallic long-barreled gun in a holster.
She first encountered its executive director, Nick Fury, aboard S.H.I.E.L.D.'s airborne headquarters, the Helicarrier, toward the end of her training, impressing Fury by tossing him head-over-heels with a judo throw after his uttering an untoward remark about female agents. The two eventually became lovers, and their relationship continued for many years.
As a result of the Contessa's remarkable talents and skills in many areas, she quickly became a leading member of S.H.I.E.L.D. She was also at one point appointed as the leader of S.H.I.E.L.D.'s Femme Force.
After the death of Captain America, a second impostor posing as the Contessa approached Dum Dum Dugan with the intent of learning the location of Fury, whom the Skrulls are seeking. After he reveals he doesn't know, the impostor stabs Dugan with claws resembling those of the X-Man, Wolverine. After Dugan's body is thrown into the ocean, the impostor takes his place. It is currently unknown where the real Contessa or Dugan are, or if they are even still alive.
