E.M. Pino (EMピーノ, Ī Emu Pīno) is a miniature "anti-bot" android who generates electromagnetic pulses (EMP) that disable all machinery and Ether Gear within range for short periods of time.[ch. 7, 10] She is built by Ziggy to become the "Light of Edens" (エデンズの光, Edenzu no Hikari), the "next generation" of androids to the Four Shining Stars,[ch. 19] but has her memory damaged by Sibir's gang after she is sent to the time-consumed planet Norma for unknown reasons.[ch. 7] After Weisz mistakenly steals her from Sibir, she is rescued by Shiki and assigns him as her new master, joining his crew in the hopes of restoring her memories.[ch. 10, 16] She later develops a desire to be reborn as a human through Mother's wish and experience sensations that she cannot feel as an android,[ch. 42, 48] being given opportunities to assume the appearance of a rabbit-eared human girl through virtual or holographic technology.[ch. 31, 72]
Mashima created Pino to serve as the mascot character of the series, with her name being a pun on "EMP".[vol. 9] During development of the manga, Mashima found it increasingly difficult to include her within the first chapter, where he incorporated Happy to stand in for her. As with Weisz, Mashima said that he found it "fairly easy" to write for Pino due to her established role in the story.[vol. 2] He later called Pino his favorite character in the series, adding that he worked out "a lot" of story details for her, and that she would "probably" become an important character.[vol. 3]
