Since before he saw Star Wars: Episode VII – The Last Jedi, Rebel Builder had been wanting to create a First Order AT-M6 walker. The upgraded version of the classic AT-AT from The Empire Strikes Back was revealed to fans before the film’s release. Rebel Builder knew from the moment he saw it what his mission was. Of course, he had to wait to see the movie. And then he had to find as much source material as possible. He spent the next couple of years drawing on behind-the-scenes books, toy models, and theme park reference pics. In August of 2020, he began construction. The final result is a 33.5-inch tall, 31.2-pound model that dwarfs LEGO’s official Ultimate Collector Series 75313 AT-AT.
