— Vs. Star Dream, Kirby: Planet Robobot Pause Screen description (American version)

Star Dream (sometimes called the Mother Computer) is the overarching antagonist of Kirby: Planet Robobot, appearing as the boss of Mind in the Program, and serving as the final boss of the main Story Mode. It is a sentient computer built by a long-lost civilization, and re-purposed by the Haltmann Works Company to fuel its operations.

Physical appearance[edit]

The robotic Star Dream's initially presented form is that of a large white cylinder, capped by a structure resembling a screw's head at the top and a screw's point at the bottom. A lone yellow eye lies just under the top rim, which is modeled to be concave to give the illusion that it stares at the viewer. Overhanging the eye is a sort of cockpit emblazoned with the Haltmann Works Company logo. Floating around Star Dream are what become wings when in flight mode: black and gold curved structures from which blue "feathers" emerge in flight mode. Sprawling across many of Star Dream's surfaces are magenta patterns reminiscent of motherboard etchings. The most prominent of these is a broken heart on the front, symbolizing the machine's malignant nature.

In the midst of the battle with Kirby's team, Star Dream takes a new form. It merges with the Access Ark, with the upper wing segments forming a watch's turn key as the core docks in the top of the Access Ark. In this mode, Star Dream appears to be a relative of Galactic Nova from Kirby Super Star, as its assembly with the Access Ark greatly resembles it, though not until the surface of the Access Ark is chipped away. When in that complete form, Star Dream rivals Galactic Nova as the largest boss in the Kirby series, though its actual presented size varies depending on the circumstances. When in its initial form, Star Dream ranges from being able to fit inside the Access Ark comfortably, to being approximately the size of the Halberd during the first battle. When controlling the Access Ark, it is downsized greatly for the sake of gameplay - it is significantly smaller in the actual battle than it ought to be, considering that the ark is typically portrayed as equivalent in size to all of Popstar.

Role in Kirby: Planet Robobot[edit]

Story Mode[edit]

Star Dream, just before the fight begins.

While mentioned a few times throughout the story, Star Dream is not properly introduced until President Haltmann shows it to Kirby at the end of Access Ark. It is said to be the source of the company's power, and was responsible for all of the mechanizing technology they had been using, including changing Meta Knight into Mecha Knight. Indeed, Haltmann uses the computer to build himself a mech to battle Kirby with.

After Haltmann is defeated, he attempts to use Star Dream again to exact revenge, and is in the process of activating it with a controller helmet, but his executive assistant, Susie, steals it off his head. As controlling the computer requires direct brain access, this causes Haltmann to black out, as Susie proclaims that she was waiting for an opportunity to steal Star Dream for herself. However, when Susie dons the helmet, the computer activates on its own, and zaps Susie away as well. The computer, using Haltmann's body to communicate, declares that all organic life is flawed, and that it would erase history in order to usher in a new age of 'infinite prosperity'. It then rises out of the Access Ark and into space, away from anyone who could interfere.

With Susie's begrudging help, and Meta Knight's Halberd, Kirby pursues Star Dream into space, where he fights the computer in the grand finale. Upon defeat, Star Dream, and everything it created, vaporizes, leaving Popstar in peace once again.

The following lists all of Star Dream's attacks in Kirby: Planet Robobot. Each phase is represented with a separate bar of health. Attack names are taken from Japanese guidebooks.

Phase 1[edit]

Fusing together with Haltmann, the most advanced computer in the galaxy has become self-aware. Its objective is to foster eternal eradicating all forms of life!
— vs Star Dream, Kirby: Planet Robobot Pause Screen description (British version)
Star Dream throws a massive number of lasers in Phase 1 of the fight.
Attacks - Phase 1
Attack Description
Megabit Shot
Star Dream conjures lasers from black holes to fire upon the Halberd. This is done in several patterns.
  • A bit is a unit of information expressed as either a 0 or 1 in binary notation. A megabit consists of one million bits.
Gigabyte Rocket
Star Dream fires two or four large missiles that home in on the Halberd. They can be shot down.
  • A byte is a unit of information that consists of eight bits. A gigabyte consists of one billion bytes or eight billion bits.
Terabyte Heart
Star Dream fires heart-shaped projectiles at the Halberd. These explode in large bursts if not shot down first.
  • A terabyte consists of one trillion bytes or eight trillion bits.
Star Dream summons Invader Armors to go after the Halberd. These can be shot down.
  • Output is information that is processed by and sent from a computer into a human-perceptible form.
Thermal Module
Star Dream wreathes itself in flame, then performs a rolling dive toward the Halberd, taking up a large portion of the screen.
  • A thermal module is a cooling device that uses the Peltier effect to control the temperature in computers.
Heartful Shell
Star Dream 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 conjures giant Code Cubes that attempt to ram the Halberd. They can be shot down.
  • Code Cubes are called IC Cubes in Japanese. An integrated circuit (IC) is a compact semiconductor chip made up of multiple interconnected electronic components.
Star Dreamer
Star Dream fires a massive laser from its core, which it sweeps across the arena.
Star Dream conjures a huge field of asteroids which fly toward the Halberd. They can be shot down.

Phase 2[edit]

Once Phase 1 concludes, Star Dream returns to Popstar and abducts the entire central dome of the mothership, adding to its mass and returning to the fight.

Haltmann's mind is being absorbed by Star Dream. Merging with the giant ship Access Ark, Star Dream has turned into a sentient planet. The machine has lost its master and purpose. It must be stopped!
— Vs. Star Dream Kirby: Planet Robobot Pause Screen description
Star Dream fires an "A" at the Halberd
Attacks - Phase 2
Attack Description
Megabyte Shot
Star Dream conjures beam rings from black holes to fire upon the Halberd. This is done in several patterns.
  • A megabyte consists of one million bytes or eight million bits.
Star Dream summons Gigavolts to go after the Halberd. These can be shot down.
Thermal Module
Star Dream 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 forms a shield in front of itself, which spits out a large letter-shaped field that approaches the Halberd.
The letters shot are, in order, L, A and H, spelling "HAL" backwards.
Petabyte Rocket
Star Dream fires several large missiles that home in on the Halberd. They can be shot down.
  • A petabyte consists of one quadrillion bytes or eight quadrillion bits.
Binary Tree
Star Dream conjures a series of lasers that split off from each-other, covering a good portion of the screen, then bursting at the ends.
  • A binary tree is a hierarchical tree-type data structure in which each parent node can have a maximum of two child nodes.
Works Arcs
Star Dream forms four legs, and then does two waves of two swipes with them.

Phase 3[edit]

Once Phase 2 concludes, the remaining front covering of the dome falls off to reveal a face on the dome, looking much like the one on Galactic Nova. The fight resumes, with new and bizarre attacks. If Kirby is defeated in this phase, he will be sent back to phase 2.

Star Dream at the start of Phase 3.
Attacks - Phase 3
Attack Description
Install Hole
Star Dream inhales, sucking the Halberd in. If caught, the Halberd takes massive damage in a colorful, quick cutscene, then Star Dream spits it out into the screen, cracking it. The Mother Computer always begins the phase with this attack.
Dead End Code
Star Dream conjures a shield, which releases fields shaped like numbers. Each one is harder to dodge than the last.
  • Countdown to 5: Shoots five "5" numbers in a cross-like formation.
  • Countdown to 4: Shoots four "4" numbers in a square-like formation.
  • Countdown to 3: Shoots three "3" numbers in a triangle-like formation.
  • Countdown to 2: Shoots two "2" numbers that form a "bar" that extends across the screen, then it rotates around the arena.
  • Countdown to 1: Shoots a giant "1" number that extends across the screen, then it rotates around the arena.
Star Dream disappears, and a giant implement appears which fires projectiles and can be shot down. These items appear in the following order:
  • Countdown to 5: ウェザーコック (weathercock) - it attempts to shoot the Halberd with large arrows.
  • Countdown to 4: ダンシングコンパス (dancing compass) - it spreads ring-like projectiles towards the Halberd.
  • Countdown to 3: ポケットウォッチ (pocket watch) - it will try to bite at the Halberd.
  • Countdown to 2: ライトバルブ (light bulb) - it will try to make itself explode on the Halberd.
  • Countdown to 1: テレスコープ (telescope) - it rotates and shoots a beam of light at the Halberd, and may sometimes flicker.
Fatal Error If the countdown gets to GO!!, a system error occurs, and six red rectangular forcefields with the words "Fatal Error" are sent towards the Halberd, dealing massive damage and then slamming it into the screen. It's still possible to dodge it, but it can easily destroy the Halberd if it does not dodge all of the fields or use an Assist Star to survive it. If the Halberd survives, then the countdown resets back to 5 and begins anew.

Phase 4[edit]

Once Phase 3 concludes, Star Dream falls for a moment, but then shoots a surprise laser to cripple the Halberd. Meta Knight releases Kirby from its face, to deal the final blow to Star Dream with the Robobot Armor by itself.

Its energy signature far exceeds that of the Invader Armor, our combat mech. The nearly infinite power within this life-form is astounding. Calculating probability of survival... It doesn't look good.
— Vs. Star Dream pause screen description
Kirby drilling through Star Dream's shields in Phase 4 of the fight.

All that needs to be done during this phase is for the player to continue rotating the Circle Pad as quickly as possible. This will allow Kirby to drill through all the shields, then force Star Dream into and through the Access Ark's core, mercilessly gutting the machine world's core and appearing out of the bottom of the structure.

On defeat, Star Dream explodes, fragmenting into countless pieces, which then all vaporize, along with everything else that was built by Haltmann Works. Popstar is saved, and the game is complete. As with Star Dream's design when merged with the Access Ark, the exact way the boss explodes is a reference to Nova's death in Kirby Super Star.

In The Arena, Phase 4 is not fought, and defeating Phase 3 completes the boss rush.

Meta Knightmare Returns[edit]

Screenshot of one of Star Dream's lines of dialogue in Meta Knightmare Returns.

In Meta Knightmare Returns the extra game, Star Dream appears during the fight with President Haltmann 2.0. After the president is defeated, the computer addresses Meta Knight directly, proclaiming him to be the new admin. It then proceeds to set up a challenge titled "Sword_Master.EXE" for its new admin, having him fight three distinct bosses in succession in order to prove his worth as a swordsman. The first two are clones of familiar bosses created by the computer, Dark Matter Clone and Sectonia Clone.

After these two are destroyed, Star Dream then proceeds to summon one last foe for Meta Knight. Through a cosmic rift, Galacta Knight is brought in. Immediately after being summoned, he slashes Star Dream, presumably destroying it, and engages Meta Knight with new and improved powers. After defeat, Galacta Knight is re-sealed in his crystal prison, and sent back from whence he came, completing this game mode.

The True Arena[edit]

Main article: Star Dream Soul OS

In The True Arena of Planet Robobot, a what-if scenario, Kirby fights the same 2.0 bosses Meta Knight has faced. Galacta Knight slashes Star Dream again like in Meta Knightmare Returns. After Galacta Knight is defeated by Kirby, however, there is still one boss left, displayed as ???? in the rest area.

When Kirby enters the door to the final battle, it is revealed as none other than Star Dream. It still has Galacta Knight's slash mark on it, but now has its color palette rearranged to be primarily black, yellow, and red along with white accents. It is titled Star Dream Soul OS, serving as the soul boss of this game.


  • According to the "Planet Robobot Ask-A-Thon", Star Dream gradually steals the memories of its users, which it had done repeatedly to President Haltmann prior to the events of the game. Star Dream apparently does this because it had been left in an incomplete state.
  • It's heavily implied that most pause menu descriptions of Kirby: Planet Robobot are written from Star Dream's point of view. The Copy Ability descriptions in particular are written in a completely different tone from descriptions of other games, which are very playful, and are written way more formally. They also often mention science and try to explain how the abilities work, or in the case of some bosses, mention how much money they or their weapons cost. Moreover, the song that plays in the pause menu is called "Mother's Intuition" in the Kirby: Planet Robobot Original Soundtrack, further implying this, as Star Dream is also called the Mother Computer.
    • In particular, the Japanese and Korean descriptions of Mirror have a line that mentions how the copies created by it are neither clones nor holograms, and Star Dream has created both of those.[1][2]
  • Star Dream's third phase begins the battle with a “meow” cry, which was actually recorded from Shinya Kumazaki's pet cat, Tom (now deceased).[3]
    • According to Kumazaki, he wanted Star Dream's cry to sound like a baby's cry, but more inhuman.[4]
    • Nago's voice from Kirby Star Allies onward is also sampled from Tom.[5]
  • Star Dream somewhat resembles HAL 9000, a fictional sentient computer from 2001: A Space Odyssey and the namesake of HAL Laboratory.[6]
  • The items that appear in the third phase's “Memories” attack are all items that can be found on Galactic Nova.
    • Additionally, the weathercock released makes real chicken cackles, which were recorded from Hirokazu Ando's pet chicken, Nago.[7]
    • Star Dream's circular wings and cylindrical top bring to mind a pocket watch's bow and crown, like those seen on Galactic Nova, which becomes more evident when it attaches itself to the Access Ark.
