Alice Beckham, a 10-year-old British former child actress from London, serves as the main pilot of the Siren-Galley transport in the Blue Sirens division of Machine Robo Rescue (MRR). Born on January 6 to actor parents, her early career in stage and film honed a charismatic persona she leverages for undercover missions, public relations tasks, and tactical deception—whether feigning distress during drills or adopting disguises. Though her initial recruitment seemed driven by a desire to amplify her celebrity status, her actions consistently prioritized rescue operations, from highway collisions and volcanic evacuations to perilous space station retrievals, often directing Support Robos via her K-BOY communicator.

Promoted to proxy Robo Master for Blue Sirens and later mentoring new MRR recruits, Alice balanced operational leadership with a complex interpersonal landscape. She harbored unreciprocated feelings for teammate Makoto Aikawa, sparking jealousy during his interactions with others like Aki Saotome, yet their partnership strengthened through high-pressure collaborations—disarming a train bomb, orchestrating disaster-prevention protocols. Alongside teammates Rin Haruka and Sayuri Suizenji, she coordinated public engagements such as the Kansai Disaster Prevention Festival, though her enthusiasm occasionally led to overcommitment.

Her growth emerged through confronting ego-driven impulses, like irritation when missions diverted attention from her, and through resilience in crises—aiding a pregnant civilian during a Gura Gorro assault or advocating for the integration of a reformed antagonist into MRR. Her performative instincts, shaped by her theatrical upbringing, gradually aligned with altruistic pragmatism. Subsequent assignments, including international disaster response and orbital rescue operations, underscored her evolution from fame-seeking recruit to a disciplined operative devoted to saving lives.
