Anya Forger, originally known as Test Subject 007, gained telepathic abilities through unspecified experiments conducted by an unknown organization. Her childhood consisted solely of strict training to develop these powers, devoid of typical activities. She escaped the facility, subsequently moving between orphanages and foster homes. Four adoption attempts failed, each ending in her return due to her secret powers and resulting perceived strangeness. Her biological mother is unknown; fragmented memories hinting at a past connection involving butterflies make this subject emotionally sensitive. Without birth records, her true age is undetermined. Initial observations estimated four or five years, though she claims to be six to qualify for Eden Academy adoption.
Physically, Anya is notably short. She has light pink hair styled with inward curls, a fringe, and a distinctive ahoge, almost always adorned with black horn-like ornaments. Her usual attire is a simple black dress with a white ribbon at home. For Eden Academy, she wears the standard blazer, white knee-high socks, and black Mary Janes. During physical education, she ties her hair back with a red headband. Prominent features include her large, oval-shaped green eyes and highly expressive facial reactions.
Her personality blends typical childlike traits—impulsiveness, distractibility, and a love for spy-themed cartoons like Spy Wars and peanuts—with complexities from her traumatic past. She exhibits a strong desire for familial acceptance and stability, fueling significant abandonment fears. This motivates her active efforts to preserve the Forger family unit, often through scheming or matchmaking between Loid and Yor. Generally optimistic and cheerful, she displays resourcefulness in high-stakes situations, though her young age shows in a tendency toward short-term solutions and difficulty grasping abstract consequences. Her instinctive reactions to overheard thoughts via telepathy cause social awkwardness, making her appear eccentric or unhinged to peers. She shows surprising emotional maturity in recognizing her parents' secret professions as spy and assassin, viewing them with admiration rather than fear, and actively supports their missions despite risks.
Her primary ability is telepathy, allowing her to read minds within a limited range, manifesting as visible spark-like imagery. Significant limitations include: overload from strong emotions causing discomfort akin to heartburn; failure during new moons ("eclipsing"); and incapacitation in large crowds due to mental overload, leading to nosebleeds or dizziness. She struggles to comprehend complex or rapid thoughts, like those of highly intelligent individuals such as Loid. Beyond telepathy, she possesses above-average strength for her size, demonstrated by punching Damian Desmond or throwing Yor's stiletto. She also shows aptitude in classical languages despite overall poor academic performance. Her resourcefulness surfaces in crises, like improvising traps or decoding future visions from Bond, the family's precognitive dog.
Her development centers on Eden Academy, where she strives to befriend Damian Desmond to advance Loid's Operation Strix mission for world peace. Academically, she consistently earns low grades (Tonitrus Bolts) due to poor study habits and reliance on telepathic cheating, which often backfires, though she excels sporadically in classical language. Socially, she forms a genuine friendship with Becky Blackbell while largely misinterpreting Damian's growing affection as hostility. Key moments highlight her courage: comforting a stampeding cow through telepathic empathy, rescuing a drowning child to earn a Stella Star, and defusing a bomb threat by interpreting Bond's visions. Her commitment to preserving her family deepens, evidenced by tearfully insisting on staying with Loid after his initial mission concludes and later expressing a desire to be with her parents "forever" during the Eden interview. While hiding her powers due to fear of rejection, she increasingly uses them to protect her family, warning Loid of traps or aiding Yor emotionally.
