She is the secretary of Colonel Erich Von Strohm. She works for Captain Hans Geering and Lieutenant Gruber too, but is also very loyal to Herr Flick. She actually works as a double agent for him and is his love interest. Helga is tall, blond, blue-eyed, and therefore a perfect example of the nazi aryan race. She often, during special operations, has to disguise herself. Her signature is her way of, when someone is about to enter Von Strohm's study, shouting the name of the one(s) entering. She is often fancied, especially by Herr Flick, who wants to marry her, but she is also very popular by General Von Klinkerhoffen. She is not afraid of taking her clothes off, revealing various fashionable undergarments. One episode concerned her silk knickers which had been stolen to repair the airmen's hot-air balloon - "Not zer vones viz zer little swastikas around zer edge?" inquired Herr Flick.
It is mentioned in one episode when Gruber disguised himself as a woman and took Helga's clothes that she has a spare wig, possibly implying that she always carries one.
She often becomes enrolled in Herr Flicks plans (that often go pear shaped) such as when she attempted to shoot a poisonous dart but ended up shooting Herr Flick (but the antidote was applied in time) and when he questioned her with the truth serum made from the Peruvian Self-Inflated Marsh Frog, caused her breasts to inflate hugely, but fortunately it stopped before she got too big and exploded. There was a short sketch made featuring her where she did get too big and her clothes exploded off her (her silk knickers where seen again in this sketch) before she reached elephantine size and exploded.
It was revealed in one episode, when she had to seduce René, that she has three swastikas tattoed on her front. She mentions in another episode that her mother is/was a poor Bavarian strudel chopper.
In the last episode it is revealed, that at the end she is married to Gruber, and has multiple children with him. Herr Flick had undergone a plastic surgery in hope to emigrate to Brazil, therefore Helga wasn't attracted to him anymore.
