How powerful was Luke Skywalker at his peak?
The tricky thing about discussing Luke Skywalker’s canonical power level is that we still haven’t really seen him in his prime in canon. “The Mandalorian” Season 2 ends with a compelling display of his lightsaber prowess, as Luke cuts his way through an army of Dark Trooper droids aboard Moff Gideon’s flagship. It’s cool, but these robotic foes aren’t exactly a proper test of Luke’s strength. It’s also worth noting that he’s still incredibly young at the time.
In “The Book of Boba Fett,” we see him training Grogu in the ways of the Force, and it’s clear that Luke is quite strong. Even so, his real prime comes in the ensuing years, as he begins constructing a new Jedi order and training padawans, including the young Ben Solo. There are a number of impressive stories from this period. In the comic “Star Wars: The Rise of Kylo Ren,” Luke fights off the assembled Knights of Ren single-handedly. Later, in the canon novel “Shadow of the Sith,” Luke faces off against a dark side cult called the Acolytes of the Beyond and duels a powerful warrior named Kiza who’s driven to evil by an ancient Sith spirit.
While these victories are notable, Luke’s most impressive feat comes in his twilight years at the end of “Star Wars: Episode VIII — The Last Jedi.” His dying act, projecting himself across the known galaxy to face Kylo Ren and aid the Resistance as an astral specter, is one of the most powerful displays of Force mastery ever seen in “Star Wars.”
