Blue Submarine No.6 (English Dubbed)

Mankind's last hope lies with the Blue Submarine No. 6 and her dedicated crew-who must fight for humanity's survival against a race of sea mutants.

With Zorndyke's forces held at bay, for the moment, after another undersea battle, Blue Submarine and her crew return to base for much-needed repairs.

After drifting out to sea, Tetsu wakes up on the hull of a half-sunken ship, surprised (and unnerved) to find himself at the mercy of his own enemy.

Zorndyke prepares to release his ultimate weapon: a race of sea mutants. His plan? World domination. But will humanity prove to be its own destroyer?
