Helga Brandt (Karin Dor) is the helicopter pilot/henchwoman of the villain Mr. Osato in YOU ONLY LIVE TWICE.
Osato orders her to kill James Bond. She seduces him first, then parachutes from a crashing plane that he is trapped in. 007 survives.
For her failure, she is dropped into a piranha pool by the archvillain Blofeld. The hungry fish make short work of the alluring but deadly German redhead.
