Movie princess who wields a blaster pistol

LEIA

This rebel leader’s iconic hairstyle and sharp aim made her a galaxy’s hope in a classic space saga.

This clue points to Leia Organa, the iconic princess from Star Wars who famously carries a blaster pistol in the original films. The word "princess" narrows it down to royal characters, and "blaster pistol" is a dead giveaway for her role in the Rebel Alliance. Since the answer is just four letters, "LEIA" fits perfectly as the short, recognizable name. If you're a Star Wars fan, this one’s a no-brainer.
