He has been on an emotional journey as he had failed in teaching new Jedi's when Ben Solo aka Kylo Ren sided on to the dark side. The man who went into exile after that was no other than Luke Skywalker, a powerful Jedi master. With his almost a no-show on "The Force Awakens", he may have recuperated well as he is now using a powerful Force to destroy the Knight's tools.
News Everyday have already confirmed of a Luke Skywalker's acquiring incredible powers that he was able to destroy the Starkiller base all by himself. As it was described, it is a much larger, powerful target than the other Death Star that Luke Skywalker and Han Solo has helped to destroy, then in this way; his acquired power has been shown to be very destructive. This may be the reason why he stayed long and didn't show up even on Episode VII and was believed to be in planet Ahch-to reflecting.
Moreover, The Christian Times have shared a video of a die-hard "Star Wars" fan as he showcases the massive strength and power of Luke Skywalker as he finishes a bigger version of the Starkiller base. This is now something to watch out for as the Jedi Master once again proves that he is worthy to be called one. The whole scene is just as exciting as it only catches a glimpse of what he can do, as the video of Mike Zeroh has not been confirmed.
The vast upcoming of spoilers and teasers also shared a chance that Luke Skywalker may eventually train Rey as expected. Although his said powers may have developed over time, Darth Vader will still get the weaker one like Rey and her character may be missing, altogether thrilling the fans of what may happen. If all these powers of Luke Skywalker are all true, then the saying suits for him as "May the Force be with you".
