Is this Masami Obari’s biggest success as a creator?
The usual angular design is toned down heavily by the intervention of Junichi Takaoka & Makoto Uno, but there’s elements in there that are obviously Obari. Namely missile-like breasts on one of the characters and drills. I sometimes think Obari’s ideal woman is Aphrodite A given how he draws women.
Anyway, usual robot protecting Earth hijinks here.
