In the original Space Battleship Yamato (1974) series, Analyzer is a squat, human-sized robot who originally worked in the EDF's hospital, Analyzer joins the Yamato crew on his own request, believing it to be the only place he can truly prove himself.

In 2199, Analyzer is illustrated just like the original, but the robot is portrayed as the purpose built autonomous sub-computer of the Yamato, and is more behaved and a bit of a deadpan.
