The Goddess of the Na'vi Brainwashes Jake in Avatar
20th Century Fox
Jake Sully is a paralytic marine in the 22nd century who makes a deal with some rich paramilitary assholes to get intel on the bipedal, cat-like inhabitants of the planet Pandora in exchange for new limbs. To do that, he pilots a genetically engineered clone of the aliens (called the Na'vi) ... right between the legs of their princess.

After the two fall in love, Jake of course switches to the side of the underdog aliens and starts fighting against his fellow humans in the name of what's right and just.
When Jake and the alien princess Neytiri choose each other as mates, they connect their brain-USB hair to the Tree of Voices, one of many spiritual sites on the planet for communicating with Eywa, the spiritual force/neural network that binds every creature on Pandora. One Reddit user's oddly convincing theory says that this scene is actually like something out of a horror movie, because what it shows is Eywa brainwashing Jake into betraying the humans and protecting the planet.

You see, right before this ceremony, Jake is a human through and through, giving intel to his bosses despite knowing full well that they are planning to raze Pandora for its precious minerals. But just a couple of hours after he connects himself to the Tree of Voices, he is suddenly ready to abandon his own species and risk his life fighting for the aliens. And it's not just him.
