Ziggy

A combat cyborg assigned the task of recovering and protecting MOMO, the 100-Series Observational Realian. Upon his death in T.C. 4667 at the age of 30, his body was donated to science, and two years later he was reborn as a combat cyborg. The last rank he held was captain of the 1875th Special Operations Command detachment of the Federation Police Bureau. He is currently appropriated to the S.O.C.E. According to Federation law, upon death, an individual's body is designated as "public property", thus they are no longer able to control their own fates. Perhaps this is why Ziggy considers himself equipment owned by the S.O.C.E. His thinking is in direct contrast to MOMO, who longs to be human. Ziggy constantly strives to turn himself completely into a machine through repeated tune-ups that eliminate his human parts, piece by piece.
His looks belie his extremely old age, and his advice gained from years of experience is both practical and precise. His former name was Jan Sauer.
