Big Shadow
voice first heard in episode 8, seen only as a shadow in episodes 11-19
Big Shadow was the leader of the Shadow. He was much calmer than Professor Gill (and much less interesting). In the beginning of the series he is obsessed with assembling the Giant Devil robot.
first seen in episode 20
Towards the end of the series Big Shadow seems to loose interest in the Giant Devil robot and thus in Akira and Hiroshi. His obsession becomes destroying Kikaida 01 and the traitor Bijinda.
