The Space Clock (aka Star Dream)

Star Dream (also known as the Mother Computer) is a powerful, malevolent machine in the Kirby series which serves as the final boss of Kirby: Planet Robobot. It was initially built as a wish-making robot and the Mother Computer of the Haltmann Works Company, but soon developed the intention to eradicate all organic life-forms.

At some point in the past, President Haltmann discovered the blueprints for a machine known as Star Dream, a powerful wish granting device. By studying ancient technology he gained the knowledge he needed to rebuild the device. During an early test of the computer(likely to be that of the Space-Time Transport program), however, there was an accident and Haltmann's daughter was lost, evidently warped to Another Dimension. Haltmann was devastated, and under the impression his daughter had perished, attempted to use the wish-granting computer to bring her back. His attempts were unsuccessful; further, Star Dream began to steadily deprive him of his memories through the program controller interfacing with his brain, due to its incomplete nature. As a result, he lost compassion and even memories of Susie's existence, changing the goal of his company to infinite prosperity. With the might of the Haltmann Works Company behind him, and Star Dream as his advisor, Haltmann began invading planets and harvesting their resources to achieve that goal. During his campaign to enslave Planet Popstar, however, Haltmann was confronted by Kirby, resulting in an intense battle that ended in his defeat. In response, an outraged Haltmann decided to activate Star Dream, only for his control helmet to be stolen by Susie.

Unbeknownst to either party, Star Dream had been studying the cosmos through the Haltmann Works Company and had gradually developed an extreme hatred towards all organic life. When President Haltmann's control device was stolen, the malevolent computer analyzed Haltmann, absorbing his memories, and even his soul, turning into a sentient, god-like being in the process. Star Dream promptly blasted Susie and possessed President Haltmann's body, using it to reveal its plan to bring eternal prosperity to Haltmann's company by wiping out all organic life. Star Dream subsequently bursts out of the Access Ark, intent on fulfilling its newfound goals.

Susie gives Kirby the Robobot Armor to combat Star Dream. Meta Knight offers Kirby to board the Halberd, but Kirby instead scans it for the Robobot Armor's Halberd Mode, and the two engage the rogue supercomputer in a fierce dogfight that ends in Kirby and Meta Knight's victory. Damaged but not defeated, Star Dream fuses with the Access Ark to become a sentient planet that attacks the two once again. In spite of the machine's new capabilities, Kirby and Meta Knight are still able to triumph, destroying the armored front of the Access Ark to reveal a modified Galactic Nova underneath, similar to the one that Kirby had previously encountered in Kirby Super Star. Though suffering major damage in the third battle that results, Star Dream still manages to fire its laser and hit the Halberd, forcing Meta Knight to eject Kirby in his Robobot Armor. Using a more powerful version of the Robobot Armor's Drill, Kirby breaks through Star Dream's defensive barriers before successfully drilling the malevolent computer's screw straight through the Access Ark, seemingly ending its threat.
