Synopsis

During World War II, Dr. Asagumo gets recruited by Hitler to help develop a mysterious superweapon called Big X. Worried about what might happen if it's actually completed, Asagumo deliberately sabotages the research alongside his fellow scientist, the treacherous Dr. Engel. As Germany's about to lose the war, Asagumo hides the formula for Big X in his son Shigeru's body before being executed by the Nazis. Fast forward twenty years. The card is discovered during an autopsy in Tokyo, but a neo-Nazi organization immediately steals it and finally finishes the weapon—turns out it's a drug that can make the human body grow infinitely large. Dr. Engel's grandson is part of the group. Now Shigeru's son Akira has to take them on, going up against the reconstituted Nazi Alliance and Hans Engel's plans for global domination.
