Bijinder, also known as Mari in her human form, is a powerful android built by the SHADOW organization and a heroine in Kikaider 01. While she would eventually become one of the protagonists of the series, in her initial appearance she was an antagonist, being used by SHADOW to destroy Kikaider 01.
She was portrayed by Sue Shiomi.
Mari was originally built by the SHADOW organization as part of a scheme by Zadam to lure Ichiro into a trap by using her to gain his trust. To make Ichiro like her, Mari was programmed to save children from SHADOW's androids, while being a remorseless assassin in her Bijinder form.
After she befriended Ichiro, Zadam used the pain circuit he installed in her to torture her so Ichiro would be tempted to rescue her. Unbeknownst to Mari, Zadam and Big Shadow had implanted a miniature H-bomb inside her body that was set to detonate if the third button on her blouse was ever undone. However, before Ichiro could undo the third button, Mari got up and walked away to keep Ichiro from triggering the bomb.
As punishment for defying SHADOW, Big Shadow had Hakaider and Zadam beat her before sending her out to redeem herself by destroying Kikaider 01. However, Mari continued to feel conflicted about her mission to destroy Ichiro and later a partially-incomplete conscience circuit installed inside her by Ichiro.
Upon learning of this, Big Shadow had his forces capture Bijinder and ordered the conscience circuit removed so she would return to being loyal to SHADOW, but Bijinder was able to break free and fight off SHADOW's forces before escaping.
