When the war ends with the Battle of Jakku and the signing of the Galactic Concordance, the young Hux and his father are part of the Imperial Navy forces who retreat into the Unknown Regions.

He serves as the right hand of the First Order's Supreme Leader Snoke (Andy Serkis), second in authority only to Kylo Ren (Adam Driver), with whom he has a fierce rivalry.

He is dedicated to destroying the Resistance, an army that grew out of the Rebel Alliance and is led by General Leia Organa (Carrie Fisher).

To destroy the Resistance, Snoke orders Hux to use the Starkiller Base superweapon against the New Republic's capital world of Hosnian Prime.

Hux gives a speech before the First Order army about the end of the Republic before Starkiller Base fires on Hosnian Prime under his command, killing billions of people in the destruction.

Hux subsequently oversees the bombardment of the remaining three ships of the Resistance, then on the lifeboats, and, along with Phasma, helps arrange the execution of Finn and Rose Tico.

[6] Hux briefly appears in segments of The Lego Star Wars Holiday Special set between the events of The Last Jedi and The Rise of Skywalker.

The episode takes place at the same time as The Force Awakens and depicts First Order troops watching a transmission of Hux give his speech and the subsequent firing of Starkiller Base.

[7] Some details about the backstory of Hux and his father Brendol appear in the 2016 novel Star Wars: Aftermath: Life Debt by Chuck Wendig.

[8] Hux also is a playable Dark Side squad leader in an update to the mobile MOBA Star Wars: Force Arena, released in late 2017.
