Lieutenant Helga Katrina Sinclair is a mercenary and a minor player in the Disney Vs Non Disney Villains and Disney Villains War. She is the secondary antagonist of the Disney film, Atlantis: The Lost Empire, usually working under the employ of her commander, Rourke.

Disney Vs Non Disney Villains
Helga plays a very minor role in the first Disney Vs Non Disney Villains War. Working with Rourke under the command of Frollo, Helga fights against the forces of Ruber and El Supremo in the Battle of Paris. In the course of the battle, she falls from a zeppelin to her death, but not before firing a final shot into El Supremo's ship, killing him.

Disney Villains War
Both Helga and Rourke are hired to help David Xanatos battle against the forces of Zurg. While she and Rourke are loading equipment onto a zeppelin, Helga encounters the energy vampire and minion of Zurg, NOS-4-A2. Rourke, after being disarmed, throws Helga at his opponent. Helga briefly outmatches NOS-4-A2 in combat, but the energy vampire gets in a lucky hit and knocks her out of the zeppelin. Helga, however, fires a modified flare gun at NOS-4-A2, knocking him into the stratosphere.
