Luisa

Animated continuity
Luisa was a teenage girl living in a mining town in Peru near an ancient Incan temple. When the Decepticons uncovered the legendary Crystal of Power in the temple, Luisa recognized what it was. Her grandmother feared it was the ancient god coming back to punish the villagers. When the Decepticons raided the town, Bumblebee and Spike Witwicky rescued her. She led them to the temple, where the Autobots were able to stop the Decepticons. When Bumblebee drove her back to the village, Luisa hoped to introduce Bumblebee to Juanita, the convertible owned by her brother.

Luisa's name is never spoken in the episode she appears.
