The game has connection to the James Bond universe
A source states, "So what's with the motion-sensor bomb found in every Smash Bros. game? What Nintendo game would have an item like that? Well, it's actually from GoldenEye 007. Later games in the series kind of had to dance around where the weapon came from, claiming it originated in a TOP SECRET game, or pretending the Smash Bros. series invented it. Another interesting Bond-related tidbit — shortly after the success of Smash Bros. in Japan, Nintendo put out a poll asking gamers who they'd want in a future Smash Bros. game. On that list? James Bond, who was one of the top vote getters. So, it seems likely Nintendo was at least considering ol' 007 for Smash Bros. at some point"(Birch).
