|~ Star Dream to Kirby through Haltmann|
Star Dream is the true antagonist and final boss of Kirby: Planet Robobot. It is an ancient wish-making machine that serves as the supercomputer for the Haltmann Works Company after it was discovered by President Haltmann.
When Haltmann is defeated by Kirby, however, Star Dream betrays and assimilates him and bursts from its pedestal before vowing to destroy all life.
Kirby pursues Star Dream using a combination of his Robobot Armor and the Halberd. After being defeated, Star Dream combines with the Access Ark, but gets destroyed when Kirby drills through the two machines and destroys the metallic heart of Star Dream.
At one point in the past, Max Haltmann, president of the Haltmann Works Company, found Star Dream in an abandoned and unknown location. By studying ancient technology, Haltmann acquired knowledge to reactivate the Mother Computer. However, an accident occurred during a test run, and Haltmann's daughter Susanna vanished. Devastated from his loss, Haltmann became obsessed with reactivating Star Dream to see his daughter again, going mad in the process. With the help of his company and his secretary Susie (who was actually Haltmann's daughter with amnesia), Haltmann began terra-forming planets to harvest their resources to activate Star Dream, starting with Pop Star.
What Haltmann didn't know, though, was that Star Dream had been studying the cosmos through the Haltmann Works Company and had grown a mind of its own and a distaste for all organic life.
After Haltmann was confronted and defeated by Kirby inside the HWC mothership, the Access Ark, he attempted to activate Star Dream to defeat Kirby, but his control helmet is stolen by Susie, who wanted to use Star Dream for her own reasons. Suddenly, she is blasted away by the machine, and Haltmann is possessed by Star Dream. Through Haltmann, Star Dream tells its plans to Kirby and blasts from its pedestal to eradicate all life. With the help of Meta Knight and the redeemed Susie, Kirby combines his Robobot Armor with the Halberd and flies after Star Dream.
After defeating Star Dream in a dogfight in space, the machine combines with the Access Ark, revealing a Galactic Nova-like head emerging from the Ark and the final form of Star Dream is born. Kirby is still able to triumph against Star Dream and uses its wishful powers against it. Star Dream attempts to take down Kirby with it by firing a laser at the Halberd, damaging it. Meta Knight extracts Kirby's Robobot from the Halberd and retreats back to Pop Star, while Kirby's Robobot creates a massive drill from its hand and charges at the machine. Star Dream attempts to block off the attack with heart barriers and charges another laser, but Kirby successfully drills the Star Dream straight through the Access Ark, seemingly destroying it.
Meta Knight Returns
Star Dream once again is found in the center of the Access Ark. After Meta Knight defeats Haltmann in his mech, Star Dream (viewing Meta Knight as its new administrator) creates clones of Dark Matter Blade (from Kirby's Dream Land 2) and Queen Sectonia to test the knight's strength. After the two are defeated, Star Dream summons a portal containing Galacta Knight from another dimension to be the final test, knowing that the knight will cause damage outside the battle. Sure enough, Galacta Knight slashes the machine once the portal vanishes, seemingly destroying it as it falls from its pedestal while the two Star Warriors battle, ending with Meta Knight's victory.
Star Dream survives Galacta Knight's attack, activating a hidden program inside the machine, resulting in its transformation into Star Dream Soul OS, the true final boss of Kirby: Planet Robobot. After Kirby fights the machine in a similar but deadlier way to the first three phases from Story Mode and fires its laser at the Halberd to separate it from Kirby's Robobot Armor, it inhales Kirby from his Robobot into the machine's core, where Kirby fights the heart of Star Dream. After being defeated, the machine makes one last attempt to kill Kirby with powerful energy waves before the heart crumbles into pieces, ending Star Dream's threat for good.
In the first phase of the final battle, Star Dream attacks Kirby by summoning lasers from black holes, missiles that can be destroyed, and summons various robots from a dimension shaped like a heart to fight against Kirby. When Star Dream is at half health, it creates a giant heart barrier, which can only be deactivated by destroying two heart halves on the barrier. While protected by the barrier, Star Dream summons massive Code Cubes to crush the Halberd. Once the barrier is destroyed and Star Dream reaches its critical point, it fires a deadly black laser, along with summoning a huge shower of giant meteors to crush Kirby, and charges itself towards the Halberd to ram into it.
When Star Dream merges with the Access Ark, it still uses the same missiles, black holes, and robot summons, only more powerful versions. During the fight, Star Dream will teleport across the background in a trick to ambush the Halberd. When enough damage is dealt, a piece of the Access Ark will break off and fling at the Halberd, revealing its Nova-like appearance underneath. Star Dream will then release a massive holographic number to ram into the Halberd (starting with L, A, and last H, a reference to HAL Laboratory, the creators of the Kirby series). Once the H vanishes, the Access Ark will grow leg-like appendages and will attempt to slash at the Halberd. Once the last piece of the armor breaks off, the legs break off and the third phase begins.
The third phase of Star Dream is a timed battle, with different obstacles appearing based on a countdown from 5 to 1. Before the fight, Star Dream will attempt to inhale the Halberd into it, which inflicts massive damage if it sucks it in. Star Dream then summons a massive hologram of a 5, followed by a 4, 3, 2, and finally 1. Star Dream then vanishes and summons a portal containing a massive object, and will respawn once the object has been destroyed or flown off screen to show the next number. When 1 passes, a hologram reading "GO!" will appear, followed by a reoccurring holographic square saying "Fatal Error" that will damage or destroy the Halberd if it touches the letters. The list of summoned objects goes as this:
|#||Object Summoned (Story Mode)||Object Summoned (Soul OS)|
|5||Weather Vane||2 Weather Vanes|
|4||Drafting Compass||3 Lightbulbs|
|3||Pocket Watch||6 Piano Tiles|
|2||Lightbulb||Spyglass and Pocket Watch|
|Go!||Fatal Error||Fatal Error (deals twice as much damage as Story Mode)|
Star Dream creates four heart barriers to stop Kirby from drilling at it, but by moving the controller in a circular formation, the drill will destroy the barriers and land on top of a massive screw on top of Star Dream. Star Dream will charge an instant-kill laser, but moving the drill fast enough will break through Star Dream and the Access Ark, destroying the two machines.
In the same cutscene, after the Robobot and Kirby are ejected from the Halberd, Star Dream inhales Kirby, leading him to the true final battle with Star Dream's heart. After the heart is destroyed, Star Dream is eradicated, undoing everything made by the Haltmann Works Company.
- It is possible that Star Dream is actually the Galactic Nova from Kirby: Super Star. Star Dream's third phase (especially the Soul OS version) looks strikingly familiar to the wish-granting machine, and all of the objects it summoned were parts from Nova's body.
- The third phase of Star Dream actively taunts at the Halberd, including moving its head in a circle, looking at it cross-eyed, or sticking its tongue out.
