star dream soul os
The upgraded version of Star Dream and true final boss of Kirby: Planet Robobot, fought at the end of the True Arena. It's implied that the soul of President Haltmann, still lingering within the machine, is being purged from its system as the battle goes on.
On the first phase, the Mother Computer has a noticeably different appearance, consisting of a golden, red, black and white color scheme and a large crack across the front from a blow dealt by Galacta Knight in a previous battle. On its third phase, its clockwork star form's color more closely resembles Galactic Nova.
The battle's final phase is completely different, involving Kirby being abducted into Star Dream and facing off its core, a robotic heart, until it finally breaks.
