In the heart of a seemingly serene suburban evening, siblings Mimi and Luke stumble upon an incredible, luminous gem while digging in their backyard. Little do they understand that this unexpected treasure will lead them into a labyrinth of cosmic chaos. That very night, a terrifying alien creature bursts forth from the earth, leaving a trail of carnage at an abandoned shoe factory. The following day, the curious siblings track this menacing entity back to its lair, where they encounter none other than the dreaded Arch-Duke of Nightmares, a dominant warrior who was banished to Earth after wreaking havoc throughout the galaxy.
As they stand before this formidable alien, it soon becomes clear that Mimi has unintentionally secured control over him through the powerful gemstone. With an air of authority, she names him Psycho Goreman, or PG for short, and begins to command him, which unsettles Luke. PG recounts his tumultuous history as a slave to the Templars on his home planet Gigax, until he fortuitously discovered the gem that granted him the formidable abilities he now possesses.
As an act of rebellion, PG formed an army, the Paladins Obsidian, and unleashed a devastating spree of destruction across the cosmos, only to be ultimately captured and imprisoned on Earth by the Planetary Alliance. In a twist of fate, as the children leave, PG sends out a signal to his former allies, marking the commencement of a gripping tale filled with interstellar conflict.
With Mimi increasingly coming to grips with her power over PG, she decides to introduce him to her parents, Susan and Greg, showcasing the gem’s remarkable capabilities. Together, they embark on family outings, with the alien becoming an unexpected companion and reluctant friend. However, their peaceful life is soon shattered when two police officers attempt to confront PG. In a fit of rage, he metamorphoses one of them into a grotesque slave, setting off a chain reaction of chaos and mayhem.
Pandora, a fierce warrior from the Planetary Alliance, arrives at the chaos-stricken police station to interrogate the remaining officer for information regarding PG’s whereabouts. Meanwhile, deep in the woods, the Paladins Obsidian re-enter the scene, disclosing their allegiance to the Templars and launching an attack on PG.
As Mimi pleads with her friend to de-escalate the situation, PG suffers grave injuries at the hands of his former allies. Regretfully acknowledging his violent past, he ultimately defeats the Paladins. But in the silence that follows, PG collapses, severely weakened by his injuries, drawing a close to this intense chapter in the story of Psycho Goreman and his unique friendship with Mimi.
In a startling moment, Greg is blessed with a vision of PG, who urgently implores him to rescue himself and the children from the wooded expanse. He complies, returning with Pandora waiting at their doorstep alongside Susan. A proposition is put forth suggesting that they hand over PG to Pandora, a notion for which Luke expresses agreement. However, Greg stands firmly with Mimi as they find refuge inside the shoe factory, evading Pandora’s formidable transformation of Susan into a fierce warrior.
As PG, desperate for recovery, reveals that only the gem can restore him, Mimi finds herself swayed by PG’s promise of protection over her and her family during his quest for vengeance across the galaxy. Unbeknownst to her, Luke has secretly taken the gem, setting the stage for an explosive confrontation involving Pandora, Susan, and Luke as they confront Greg, Mimi, and PG.
The ensuing battle escalates into complete bedlam as Luke tries to steer Mimi away from the alien, illuminating the corruption the gem’s power can instigate. Just as Pandora is about to strike the final blow against PG, he challenges her to a game of Crazy Ball, a unique sport invented by Mimi and Luke.
With Mimi’s team claiming victory, Pandora disregards the outcome and attacks PG regardless. In a split second, Susan intervenes, utilizing her own newfound powers to safeguard Mimi; but Pandora, not one to be underestimated, reverts her back to her human form. In the face of the storm, Luke and Mimi reconcile, ultimately deciding to relinquish the gem to PG, which rejuvenates him.
Empowered by their love, PG unleashes his fury upon Pandora, consuming her very essence. Now energized by the warmth of their bond, he returns the powerless gem to Mimi, asserting that witnessing their unyielding love has irrevocably changed him. He vows to harness this newfound strength for destruction across the universe, yet he assures his newfound companions that he will allow them to remain unharmed.
As the family bids farewell to PG, they watch in horror as their town succumbs to the devastation of his giant form. The news updates reveal a harrowing truth: PG’s relentless path of destruction has only just begun, and within the depths of space, the Planetary Alliance deliberates their uncertain fate as they anticipate PG’s inexorable return.
