Amilyn Holdo

Amilyn Holdo is a character from Lucasfilm's 2017 Star Wars saga film the Last Jedi, sequel to the first seven films. She serves as a Vice Admiral in the Resistance during its conflict with the First Order. Following the Hosnian Cataclysm, she helps General Leia Organa lead the Resistance.

History
Amilyn Holdo and Leia Organa met as teenagers when both served in Coruscant’s Apprentice Legislature, with the outspoken, unconventional Gatalentan and the tart-tongued, driven Alderaanian becoming unlikely friends. Holdo joined the Resistance and attained the rank of vice admiral, commanding the Ninka.

After Leia was injured in a First Order attack, Holdo transferred her flag to the Raddus and assumed command of the Resistance. Her insistence on secrecy and her abrupt way of dealing with officers led to friction between her and Poe Dameron, with the starfighter ace plotting to undermine her authority.

After Poe mutinied against Holdo, she and her loyalist officers fought back, firing stun blasts at their fellow Resistance members. After Leia ended the mutiny, she and Poe evacuated the Raddus, but Holdo remained behind to pilot the cruiser. When the First Order targeted the transports, she gave her own life so they could escape, jumping the Raddus to hyperspace and tearing the First Order’s flagship in two.

Trivia

 * According to Laura Dern, Amilyn Holdo was Force-sensitive.
 * During the scene in which Holdo stuns Poe Dameron, Laura Dern accidentally said "pew pew" while firing the blaster. This blooper can be seen in the finished film.
