Star Dream Soul OS
|The final program has been activated. Its calculated victory probability is 99.99%. However, a small bit of Haltmann's soul has yet to be purged, which could throw a wrench in its plans.|
— Kirby: Planet Robobot Pause Screen description
Star Dream Soul OS bears the scar left on its surface when Galacta Knight struck it. It also possesses President Haltmann's rapidly dwindling soul in its operating system, hence the name. It fights similarly to its Story Mode counterpart, with two notable exceptions. Its attacks are much more powerful, and the final phase is completely different.
The following lists all of Star Dream Soul OS' attacks in Kirby: Planet Robobot. Each phase is represented with a separate bar of Vitality. Attack names are taken from Japanese guidebooks.
|Attacks - Phase 1|
|Megabit Shot||Star Dream Soul OS conjures lasers from black holes to fire upon the Halberd. This is done in several patterns.|
|Gigabyte Rocket||Star Dream Soul OS fires four large missiles that home in on the Halberd. They can be shot down.|
|Output||Star Dream Soul OS summons Invader Armors to go after the Halberd. These can be shot down.|
|Terabyte Heart||Star Dream Soul OS fires heart-shaped projectiles at the Halberd. These explode in large bursts if not shot down first.|
|Thermal Module||Star Dream Soul OS wreathes itself in flame, then performs a rolling dive toward the Halberd, taking up a large portion of the screen it does this twice.|
|Heartful Shell||Star Dream Soul OS conjures a heart-shaped force field to defend itself. Pieces of it can be fired at to break the shield.|
|Grand Code Cube||Star Dream Soul OS conjures giant Code Cubes that attempt to ram the Halberd.|
|Star Dreamer||Star Dream Soul OS fires a massive laser from its core, which it sweeps across the arena. Then, it fires two massive lasers from its core, which it spirals around the arena.|
|Asteroid||Star Dream Soul OS conjures a huge field of magmatic asteroids which fly toward the Halberd. They can be shot down.|
Once Phase 1 concludes, Star Dream Soul OS returns to Pop Star and abducts the entire Access Ark, adding to its mass and returning to the fight.
|"Why did I reactivate such a terrible machine? Oh, I remember--I wanted to see her just one last time. How foolish! I should have known that no machine could make such a dream come true."|

|Attacks - Phase 2|
|Install Hole||Star Dream Soul OS inhales, sucking the Halberd and several asteroids in. If caught, the Halberd takes massive damage. Otherwise, Star Dream Soul OS then spits the asteroids back out at the Halberd.|
|Megabyte Shot||Star Dream Soul OS conjures beam rings from black holes to fire upon the Halberd. This is done in several patterns.|
|Thermal Module||Star Dream Soul OS wreathes itself in flame, then performs a rolling dive toward the Halberd, taking up a large portion of the screen.|
|Ground Shield||When a piece of the mothership's shell breaks off, the debris can crash into the Halberd.|
|Haltmann Works Company||Star Dream Soul OS forms a shield in front of itself, which spits out a large letter-shaped field that approaches the Halberd.|
|Petabyte Rocket||Star Dream Soul OS fires several large missiles that home in on the Halberd. They can be shot down.|
|Binary Tree||Star Dream Soul OS conjures a series of lasers that split off from each-other, covering a good portion of the screen, then bursting at the ends.|
|Works Arcs||Star Dream Soul OS forms four legs, and then swipes with them.|
|Output||Star Dream Soul OS summons Gigavolt IIs to go after the Halberd. These can be shot down.|
Once Phase 2 concludes, the remaining front covering of the dome falls off to reveal a face on the dome, looking much more like the one on Nova. The fight resumes, with new and bizarre attacks.
|Attacks - Phase 3|
|Star Dreamer||Star Dream Soul OS fires two massive lasers from its eyes, which it sweeps the arena with.|
|Dead End Code||Star Dream conjures a shield, which releases fields shaped like numbers. Each one is oddly easier to dodge than the last.|
|Memories||Star Dream disappears, and one or more giant implements appear which fire projectiles or attempt to collide with the Halberd and can be shot down. These items appears in the following order:
|Fatal Error||If the countdown gets to GO!, a system error occurs, which is extremely difficult to dodge and will almost certainly defeat the Halberd.|
Once Phase 3 concludes, Star Dream Soul OS falls for a moment, but then shoots a surprise laser to cripple the Halberd. Meta Knight releases Kirby from its face, to engage Star Dream Soul OS one last time with the Robobot Armor by itself. However, this time, Star Dream Soul OS inhales Kirby. Inside, Kirby must then contend with the very heart of the computer, in a completely distinct final battle in a circular arena.
|All of Haltmann's memories have been deleted from the OS. Even his soul--the last trace of Haltmann-- has vanished. Star Dream has gone from a near-perfect being to a cold, mindless machine.|

|Attacks - Phase 4|
|Flip-Flop||Star Dream Soul OS rotates pillars around the arena, which contain pieces that need to be destroyed. Pillars that are still intact damage Kirby on contact. As they reposition, they occasionally leave stars behind. This is reminiscent to the fight with Galactic Nova Nucleus.|
|Output||Star Dream Soul OS brings in either two Waddle Doos, two Chemitorys, two Westers, or two Capsule J3s to get in Kirby's way.|
|Heartful Tears||Star Dream Soul OS sweeps the arena with lasers. Once this is done, each section of the arena erupts in an energy flash, two-by-two, creating many stars.|
|Supervisor Call||Star Dream Soul OS shoots out numerous explosives which can be swallowed and spat back.|
|Feint Heart - Shooter Cutter||Star Dream Soul OS warps around, then stops and shoots out four cutter-like projectiles which rapidly weave in and out. These can be swallowed and spat back.|
|Deadly Heart||Star Dream Soul OS splits in half, referencing Marx, and slides across the arena, then recombines, creating a huge explosion and several stars. It does this several times.|
|Heartless Tears||When Star Dream Soul OS' Vitality is depleted, it returns to the center of the arena and pulsates violently. As it dies, it releases a last-ditch series of waves to try and take out Kirby. the player will actually need to control here, because if Kirby is not at full Vitality himself, he is guaranteed to be taken out if one of those waves hits, and will ignore invulnerability frames on any moves.|
After the waves are dodged, the heart rises, shakes out of control, then shrinks. It pauses for a moment, then explodes, fracturing the heart in two, then crumbling into pieces.
- While Star Dream spells 'HAL' backwards, Star Dream Soul OS spells it forwards.
- Star Dream Soul OS's coloration is reminiscent of Nova from Kirby Super Star.
- This is the first boss in Kirby series history to possess a post-defeat attack, and an all-but lethal one at that.
- President Haltmann's voice can be heard crying out every time a piece of the Star Dream Soul OS core is destroyed and when the core itself crumbles away.
- There are a few missing lines from the Japanese version of the pause Special Pages:
- Phase 1's Japanese Special Page describes that the final program has been "unlocked due to unknown damage (未知ノ ダメージに ヨリ、最終プログラムが アンロック。)", which implies that this soul form is caused by the attack of Galacta Knight Returns.
- Phase 4's Japanese Special Page has an additional line at the end: 夢も見ない、ゴハンも食べない、そんな あいては もはや、星のカービィの てきでは なかった! ("A being that can't dream or eat is no match for Kirby of the Stars!")
- When Star Dream Soul OS begins it's 1st phase, it spurts blood (More than likely oil due to it being a mechanical entity). This is one of the few Kirby series bosses to have a depiction of blood. The others are Shadow Dedede, Dark Meta Knight, Zero, 0², and Void Termina (Phase 2)
- The French, Italian and Spanish names of Star Dream Soul OS do not have any depiction of "soul".
