Storyline of Super Smash Bros. XCI/NSP

Super Smash Bros. Ultimate is mainly a fighting game. It does not have one big story for every fight. You choose a character and battle on different stages. Each match has its own winner.

The game has a story mode called World of Light. At the start, a powerful being named Galeem captures the fighters. Kirby escapes and sets out to help them. He travels across a large map to find his friends.

As Kirby wins battles, more fighters join the team. Together, they face new enemies and move closer to Galeem. Another powerful being, Dharkon, also stands in their way. The team must face both to save everyone.
