#1736. The three cut fighters from Brawl all left for verying reasons. Nana had to get her leg amputated due to an injury she had received from Tabuu before the events of Smash 4, making her unable to participate, and Popo refused to go alone under any circumstance. Lucas personally requested to leave. Wolf simply vanished without a trace. No one noticed for well over two years. Oddly enough, Kirby was the first one to notice.
