Harvey Yena

"I suspect that there are more in the Organization. Dr. Harvey Yena and Dr. Peter McCain to be precise."

- Edward Richtofen in Call of the Dead

Harvey Yena is an American member of Group 935. He is mentioned by Edward Richtofen in a radio on Call of the Dead. He created the Hyena Infra-Dead as it is a reference to his name being H. Yena. It is possible that he is the same person that was hung in Shi No Numa after the events of Group 935. He most likely wrote the following line on the chalk boards in Der Riese: "HYENA, Edward I know it was you, why won't it work any more."
