Mariko was a GothCorp scientist.


Mariko was a cryogenics specialist at GothCorp, and good friends with Bruce Wayne and Dick Grayson. Seeking to learn more about the medical aspects of cryogenics, Bruce asked Mariko. Though it was not her specialty, she did point Bruce to the foremost expert on the matter, Gregory Belson. However, no one had seen him for a while.
