From the introduction:
With an army of Master Hands under its control, Galeem sought to create a new world. The fighters and their countless stories… came to an end as light consumed them. Thus, the universe was crushed in the hands of Galeem. Those who fought the light were devoured. The others lost their bodies and became spirits. Only one survived… A star of hope twinkled faintly as the dust settles on a new world.
Galeem copied the fallen fighters, creating empty puppets in their likenesses… Then, Galeem forced the captive spirits to pull the puppets’ strings. This army of puppet fighters spread themselves across the last remaining world. Can anyone free the spirits from Galeem’s control? Is there any hope for the fallen fighters? The journey to defeat Galeem begins…
You arrive in this world as Kirby prepares to set out on his journey to defeat Galeem and save his friends.
