Masahiro Sakurai, the creator and director of the Super Smash Bros. series, gave fans some insight into the creation of the fighter reveal trailers that have been made for the franchise over the years. Nintendo's crossover franchise has been famous for its extensive character roster, picking fighters not only from Nintendo's catalog but also several third-party fighters from across gaming history. One of the most exciting parts about a Super Smash Bros. game is the roster, especially during the pre-release period going into a game or with DLC fighters, which became more prevalent with the fourth and fifth titles in the series, Super Smash Bros. for Wii U and 3DS and Super Smash Bros. Ultimate.
