Boss Chiki is the primary antagonist of the anime Gelpiyo, serving as the head of the Gel Factory. Operating from within the mysterious setting known as Gel Town, Boss Chiki is the mastermind behind a scheme for world domination. This ambition drives the central conflict of the series, as his plan involves the mass release of the Gel Piyo creatures into toy capsules and UFO catchers, unleashing them upon the town and beyond. His motivations are rooted in a desire to control the world through this peculiar invasion, though his methods rely on the unique nature of his creations.

The creatures released by Boss Chiki, the Gel Piyo, possess what is known as an Alpha Gel constitution, meaning no matter how much they are squashed, they bounce right back. This resilient quality ensures that his scheme perpetuates a continuous, nonstop slapstick commotion throughout Gel Town, as the creatures get swept up in the local culture and seasonal events despite his villainous intentions. Boss Chiki's role in the story is therefore that of the instigator, whose actions set the stage for the daily chaotic adventures of the Gel Piyo. While the focus of the narrative remains on the creatures themselves and their interactions with the town, Boss Chiki is identified as the boss of the Gel Factory, placing him at the center of the plot as the source of the gel creatures. His key relationship is with the Gel Piyo, which he creates and deploys as part of his plan. In terms of development, he is established as the consistent force behind the world conquest plot, and his notable abilities appear to be managerial and strategic, centered on his leadership of the Gel Factory and his capacity to devise and execute the scheme that releases the Gel Piyo en masse.
