Mary Shelley is a Lynx appearing in Armored Core 4. She is ranked as the #5 Original and is recognized as Bernard and Felix Foundation's most revered pilot. Renown for her legendary skill as a sniper, her combat style helped shape her corporation's philosophy.


Mary Shelley is a competitive and confident Original who experienced considerable success during the National Dismantlement War. She achieved a legendary status, known as a NEXT-killer, ranking second only to Anjou in the numbers of Ravens felled. After the war, Mary Shelley became the figurehead of Bernard and Felix Foundation. Wong Shao Lung served as her caretaker at this point.

    • "Goodness... Come all this way to die, have you?"
    • "You make a nice target."
    • "What a useless man..."
    • (Upon Receiving Heavy Damage)"Hmph, you're pretty good. It's useless though. We're different animals."
    • "What is it with you?!"
    • "What?! Is this it? No, I can finish this."
    • (Upon Defeat) "Why...? But my... superiority is..."


Mary Shelley is shown to be extremely confident in her ability as a NEXT pilot. This is shown by her dialogue with phrases such as "Goodness… Come all this way to die, have you?".
