Cyrus Ishitaka (SEY 2521 - 2546) was a United Planets of Earth Army veteran (Corporal, honorably discharged) squadmate of Ivar Messer I who participated in the Battle of Idris IV. Little is known about his private life outside of multiple arrests for narcotic possession and distribution. He was later implicated to be one of the two people who allegedly perpetrated a series of bombings of the United Planets of Earth by order of Messer in 2546. Ishitaka, a demolitions expert in the Army, was present on four of the five planets that bombed and found dead less than a week after the final attack. The autopsy found traces of a chemical used in the bombings under his fingernails.
