Last Hope and is now working with Double and Marie, the current Skullgirl. Valentine is one of the playable characters in Skullgirls, replacing Squigly and Umbrella in the initial line-up so there would be a playable villain during the game’s release. As her bio suggests, little is truly known about Valentine apart from her service as a Last Hope operative and servant of valentine day for boyfriend gift Skullgirl. Her motive to join the Skullgirl was chiefly out of self-preservation, but also in the hopes of researching the powers that control the Skull Heart behind enemy lines.

Despite taking orders from higher powers, Valentine’s actions are largely influenced by her own personal agenda. What precious little that is known about Valentine is evidenced in her story mode and combat dialogue. She often comes across as impersonal and condescending, with little emotional fluctuation. She does not hesitate to resort to murder and, aside from feeling slight guilt toward Painwheel, has no real morality. An interview with Alex Ahad states that despite her demeanor Valentine “acts like a jerk” to conceal her good intent and emotions. As mentioned prior Valentine had a tendency to go against orders from her superiors to pursue what she feels is right.

Patty refers to Valentine as an overachiever with a big ego. Easter, though jokingly, backs this claim up. Valentine has shown a fondness for medical science and learning, and often refers to her own actions as parts of “experiments” or “research”. This is especially apparent when she encounters Ms. Fortune, and becomes intrigued to Ms. Fortune’s paradoxical existence to the point of attacking her with the intent of cutting her open.

She hates Brain Drain so much that she became an assassin to kill him. She also seems to despise the Medici Mafia and anything related to them mainly because of their criminal activities and because of the fact they are the main reason of the corruption in the city. Outside of her “job”, she’s a very straightforward person and her sexual act is just a part of her kunoichi technique. Valentine had a rough childhood and entered to the labs early on, for training purposes. Valentine lost her eye in the incident that destroyed Lab 7.
