Mary Anne Armstrong, also known as Dr. Mary Ann Collins Armstrong, is a central character in the 2023 live‑action Philippine television series Voltes V: Legacy. She is a highly educated and skilled scientist who serves as the mother of the three Armstrong brothers—Steve, Big Bert (Robert), and Little Jon (Jon). Her background is that of a dedicated single parent, as her husband Ned Armstrong left Earth under circumstances connected to the larger conflict, forcing her to raise her children alone. This combination of professional responsibility and personal sacrifice shapes her personality: she is portrayed as strict, intellectual, serious, and disciplined, yet underneath that stern exterior lies a deeply loving and protective mother. Mary Anne’s primary motivation throughout the story is the safety and well‑being of her sons, even as they become pilots of the super‑robot Voltes V and face the invading Boazanian forces. Her role in the narrative is that of an emotional anchor and moral compass for the Armstrong brothers; she supports them from the sidelines, trains them when she can, and ultimately makes the ultimate sacrifice for them. In one of the series’ most pivotal moments, she gives up her own life to protect her sons from the Boazanian beastfighter Vaizanger, demonstrating that her love and courage override any personal fear. Her key relationships are with her three sons, each of whom she treats according to their individual personalities—she balances the serious and responsible Steve, the more impulsive Big Bert, and the curious young Little Jon. She also shares a complicated and distant bond with her missing husband Ned, whose absence weighs on the family. Over the course of the series, Mary Anne undergoes noticeable development: she learns to trust her children’s abilities and choices, moving from a cautious, overprotective parent to someone who allows them to face danger for the greater good of Earth. In terms of notable abilities, Mary Anne does not possess superhuman powers; her strengths lie in her scientific intellect, her ability to manage a household under extreme pressure, and her unyielding resolve as a mother and scientist. She embodies the theme of maternal sacrifice that runs through the series and remains a grounding presence for the Voltes V team.
