This article is about a villain in Shichisei Toshin Guyferd.
Megumi Shion (紫苑恵, Shion Megumi): A scientist who took Shiroishi's place in Fallah research, using her Mutians to capture Gou to research his anatomy to perfect the ultimate soldier project. But once it became possible to infuse a Guyborg with a Fallah, her mission changes to eliminate Gou. While investigating Bicross' damaged chest armor, she is contacted by Zodiac who offers her a new place in his new world order. Accepting his offer, she kills the Crown staff and sets the Crown base to explode before sicking Deathferd on Gou while attempting to escape. However, she is pursued by Shiroishi and their fight over the Fallah data ends with her losing her footing and falling off a cliff. But Shion is found by Metal Master and underwent Guyborg modification to rebuild her shattered near-death body, becoming the Guyborg Metal Shion. Armed with a rapier while wearing a cloak and fedora to conceal her cybernetic body, Shion vows a vendetta on Gou for her current condition despite the irony that she robbed people of their humanity in her Fallah experiments. Though ordered to bring Gou before Zodiac to have him join Crown, Shion expected it not to happen and Shion kidnaps Rei to get Gou to come to her so she can kill him, wounding the girl in the process.
