*Spoilers for Star Wars: The Rise of Skywalker continue below*
In the closing moments of The Rise of Skywalker, Ben Solo abandons his identity as Kylo Ren and leaves the Dark Side behind. He sets off on a quest to find Rey on Exegol, and when he arrives he's greeted by the Knights of Ren. He needs to get through them before he can help Rey defeat Emperor Palpatine, and he does so with Luke Skywalker's lightsaber.
Rey slides the lightsaber over to Solo when she realizes he's no longer fighting for the Dark Side, and he activates it behind his back. Pulling out the lightsaber, he taunts the Knights of Ren with a sly shrug. It's a charming moment in an otherwise divisive film, and fans have started to recreate it as part of what's become known as the Ben Solo challenge.
Take a look at what people have brought to the viral challenge below.
