Description
Created in 1972 through Otto Apocalypse's genetic experimentation, Theresa Apocalypse is a synthetic lifeform combining DNA from Kallen Kaslana and the Honkai Beast Vishnu. This hybridization granted her enhanced regeneration, superhuman strength, and high Honkai energy resistance, but halted her physical development around age twelve, leaving her permanently childlike in appearance. Chronologically approximately 45 years old as of 2017, she retains the stature and features of a preadolescent, characterized by white hair often in a low side ponytail and bright blue eyes. She typically wears frilly, cute attire matching her youthful presentation.
Originally designated A-310 within Otto's A3 clone series attempting to resurrect Kallen Kaslana, she outperformed other clones in rigorous tests. Otto subsequently acknowledged her as a distinct individual rather than Kallen's reincarnation, naming her Theresa and adopting her as his granddaughter, establishing their complex familial dynamic.
Her personality reflects Kallen's kindness and concern for others, tempered by her own stubbornness. She occasionally leverages her childish appearance tactically. Despite her mature sense of responsibility as St. Freya High's principal, she retains childlike enthusiasms: a fondness for sweets, the HOMU franchise, and reading manga—a hobby she attempts to conceal. She self-proclaims the title "World's Cutest Valkyrie," incorporating this motif into her combat phrases.
Key historical involvements include her role as an S-rank Schicksal Valkyrie during the 2000 Second Eruption. There, she formed a close friendship with Cecilia Schariac, later becoming a self-proclaimed aunt to Cecilia's daughter, Kiana Kaslana. Theresa confronted the Herrscher Sirin wielding the Divine Key Oath of Judah. After Cecilia's death, she conspired with Siegfried Kaslana to rescue infant Kiana from Otto, leading to a confrontation where Otto retained custody. Theresa subsequently transferred to Schicksal's Far East Branch, founding St. Freya High in 2009 as a Valkyrie academy.
In 2014, she recruited the amnesiac Kiana Kaslana clone (K423) into St. Freya after the Nagazora incident. She later learned K423's true origin during the Anti-Entropy Invasion but continued protecting her from Otto, culminating in open rebellion during the Battle of Schicksal.
Within the slice-of-life spinoff "Cooking with Valkyries II," Theresa appears in relaxed settings, engaging in meal preparation and casual interactions with characters like Kiana Kaslana, Raiden Mei, Bronya Zaychik, Fu Hua, and Rita Rossweisse. These vignettes depict her camaraderie during daily activities such as cooking. Her preferences, including an enjoyment of bitter melon juice, occasionally feature.
