Lieutenant Helga Katrina Sinclair (or better known as Helga Katrina Sinclair, Helga Sinclair, or simply Helga) is the secondary antagonist of Disney's 41st full-length animated feature film, Atlantis: The Lost Empire. She is the right-hand of Commander Lyle Tiberius Rourke.
She was voiced by Claudia Christian.
Helga is cunning and manipulative, while also being clever and loyal. She is a powerful and intellectual master at manipulating others to do her will, using her sharp tongue and good looks. She is also an aggressive and belligerent fighter who embraces her anger and greed when she feels she has to get physical. Despite all of this, she has a sympathetic and charming side, as she is suspicious and reluctant (even though she goes through with it) to attempt genocide, and will turn against those she feels have betrayed her.
Helga first appeared in the apartment of Milo James Thatch (the protagonist of the film), where she introduces herself to him and announced that her employer Preston Whitmore (who is a close friend of Milo's grandfather Thaddeus) is funding an expedition to find the lost city of Atlantis and that he wants Milo to be a part of. Sensing this as an opportunity to prove his claims about Atlantis true to the public, Milo happily accepts the proposition.
During the journey, Helga is seen aiding her boss and the team into successfully locating the lost city (thanks to Milo's deciphering of the Atlantean language on the Shepherd's Journal); she even took note to see how happy Milo is after finding the lost city. However, it turns out that Helga herself is aware of the existence of a powerful crystal called the Heart of Atlantis and that she, Rourke and their soldiers are planning to steal it to make themselves rich. Despite her greedy nature, Helga becomes remorseful when she discovered they were going to steal from an ancient yet living civilization and showed some concern over it, though this did not stop her from going along with the plan.
During the final battle, Helga uses her pistol to shoot back against the heroes, but Milo crashes his flying stone fish into the blimp, causing it to descend further. To lighten the load on the balloon, Rourke betrays Helga by attempting to throw her off, but she glides back and beats him up, berating Rourke for his treachery. However, Rourke grabs her foot and successfully throws her out, where she hits the base of the volcano while Rourke taunts her by saying that it's nothing personal.
Using the last of her strength, Helga repeats the exact words that Rourke said to her as she manages to fire a flare gun at the blimp, causing it to descend rapidly further. This allows Milo to defeat Rourke by crystallizing and shredding him to pieces with the blimp's propellers and return the crystal to save Atlantis from an imminent volcanic explosion. It is unknown whether she died afterwards from her fall or if she was killed when the volcano erupted. Her fate is currently unknown.
In the end, the crew return back to the surface while Milo stays behind in Atlantis to help rebuild its former glory, and they (along with Mr. Whitmore) form a cover story to keep the existence of Atlantis as a secret, describing Helga's fate as that she went missing in action, though Cookie almost spilled the beans on Helga's true circumstances before Mrs. Packard silences him.
- She is very similar to the following villains:
- Fidget from The Great Mouse Detective, both being thrown overboard to "lighten the load", yet still surviving the fall. However, unlike Fidget, Helga didn't back down until she was thrown overboard again.
- May Day from A View to a Kill; both serve as right-hand women to their bosses (Rourke and Max Zorin), who subsequently betray them for their greed. The betrayals also led the women to sacrifice themselves to defeat their bosses in their plots (Helga shooting down Rourke's blimp to prevent him from escaping before dying, and May Day sacrificing herself to foil Zorin's scheme of destroying Silicon Valley). To be fair, their bosses were Pure Evil.
- Though she chose to accompany Rourke when he left with the Heart Of Atlantis, she had second thoughts about stealing from Atlantis when it became apparent that the Atlanteans were not extinct and that their city was still thriving.
- This, along with Rourke's betrayal, has led to several fan theories that Helga changed her ways and joined the Atlanteans during the film's climax. Some even go so far as to suggest that she not only survived her fall from the balloon but was pardoned by and joined the Atlantean society. The Disney Wiki even states this in the article for the character, though there is no canonical evidence for this.
