Masahiro Sakurai is best known for creating two of Nintendo’s biggest franchises, Kirby and Super Smash Bros. It therefore makes sense that one would have inspired the other. Speaking at the Kirby 25th Anniversary Orchestra Concert in Tokyo, Sakurai discussed how the concept of characters dying after flying off the screen was almost featured in Kirby’s Dream Land. This would go on to become the core concept of the Super Smash Bros series. While he admits it wasn’t a direct copy, it would make sense that he would have subconsciously reused the idea.
