While Luke Skywalker may have been Rogue Squadron's first flight leader in the Star Wars galaxy, Wedge Antilles was the pilot who made the squadron truly great. Sure, Luke blew up the first Death Star and became renowned as one of the best pilots in the galaxy, but Wedge was the one who destroyed the second battle station (and he didn't even need the Force). In the old Legends comics, Wedge even took command of Rogue from Luke, making him largely responsible for the great legacy and prowess the squadron would go on to have in the days of the New Republic, and hopefully the same could be said for the official canon from Disney. Luke might have named and lead the team first, but Wedge is responsible for making the squadron soar.
In the official canon, Rogue Squadron came into being as a group of X-Wing pilots comprised of the former Red Squadron that flew into battle against the first Death Star. During the events set between A New Hope and Empire Strikes Back, Luke learned of the heroic actions taken by Jyn Erso and the crew of Rogue One. Seeking to honor their sacrifices in obtaining the first Death Star plans for the Rebellion, Luke named his new team Rogue Squadron. Furthermore, he took on the callsign "Rogue Leader" while the other pilots had numbers, as the name Rogue One was to be permanently retired out of respect for the fallen heroes.
However, when the Rebels established their new base on the ice planet Hoth, Rogue Squadron would transition its pilots from X-Wings to snowspeeders, where they eventually engaged with the Imperial's invading ground troops and AT-ATs during Empire Strikes Back's first act. In the aftermath, the Rebellion was scattered across the stars, forcing Wedge Antilles and Wes Janson to create a new Squadron, going back to the name Red as many Rogue pilots were lost during the Battle of Hoth. However, this is where the official canon ends for Rogue the time being and Legends begins. In the old Legends comics that have now been rendered non-canon, Luke Skywalker would eventually hand over the reins of command to Wedge in the aftermath of the Battle of Endor and the rise of the New Republic. This was because Luke felt the call to create the New Jedi Order, and their exchange can be seen in the prequel miniseries X-Wing: Rogue Leader from Dark Horse Comics.
One can imagine that a similar transition must have happened in the official canon, as Luke did indeed attempt to create a New Jedi Order in the Disney timeline. In Legends, Wedge would go on to shape and guide Rogue Squadron into one of the New Republic's best and most effective flight teams, as detailed not only in the 35-issue Star Wars: X-Wing Rogue Squadron series from Michael Stackpole and Gary Erskine but also in the various Rogue Squadron novels Stackpole wrote as well. Rogue Squadron became so popular that it also spawned an immensely loved video game series as well. Throughout them all, Wedge was the common denominator, serving as the main protagonist and consistent leader, though Luke would show up in various places from time to time.
While the exact setting in the Star Wars timeline is unclear for Patty Jenkins' Rogue Squadron feature film coming in 2023, one would hope that the legacy of the Legends' Rogue Squadron will be honored and remembered, with some specific focus on Wedge himself. Without Wedge, Rogue probably wouldn't have gone on to have the levels of success and popularity that it did. Not only was Wedge their longest-running and most effective leader, but he was also the squadron's heart in the comics from Dark Horse as well as in the novels. Who knows? Perhaps Wedge could get a cameo in the film played by original actor Denis Lawson similar to the one he had in Rise of Skywalker? Better yet, if the films' set in the days of the New Republic or after the Sequel Trilogy, perhaps Wedge could have a bigger role and recruit the next generation of Rogue Squadron pilots in the Star Wars galaxy? One can only hope.
