Plankton’s Background Story
Plankton hails from a microscopic species and is known for its single-celled size but massive ambitions. He grew up alongside Mr. Krabs in Bikini Bottom, where the two shared a close friendship during their youth. They even collaborated to open a burger joint called “Stinky Burgers.”
However, their partnership ended in rivalry after Mr. Krabs’ recipe for Krabby Patties gained immense popularity, leaving Plankton’s side of the business in the shadows. This fallout marked the beginning of Plankton’s lifelong obsession with obtaining the Krabby Patty secret formula, believing it to be the key to his success.
Plankton’s backstory highlights his insecurities and desire for recognition. Despite his intelligence, his constant failures stem from overcomplicating his plans or underestimating the loyalty of Mr. Krabs’ customers. His struggles make him a sympathetic villain, offering depth to his character.
Relationship with Mr. Krabs
Plankton’s relationship with Mr. Krabs is the cornerstone of his story. Once best friends, their rivalry transformed into a full-blown feud after the Krabby Patty success. Plankton views Mr. Krabs as the ultimate obstacle standing in the way of his dreams. Meanwhile, Mr. Krabs regards Plankton as a harmless nuisance, albeit one he must constantly thwart.
Over the years, their relationship has evolved. In certain episodes, glimpses of their former friendship emerge, showing that beneath their rivalry lies a complex bond. For instance, in “Friend or Foe,” a flashback episode, viewers see the origins of their rivalry and the camaraderie they once shared. Despite their animosity, there’s a sense of mutual respect, even if it’s buried beneath layers of pettiness and competition.

Relationship with SpongeBob
Plankton’s interactions with SpongeBob are often comedic and layered with irony. SpongeBob, as the Krusty Krab’s most loyal employee, is Plankton’s biggest obstacle in stealing the secret formula. Time and again, Plankton attempts to manipulate or outsmart SpongeBob, only to be foiled by SpongeBob’s naïve optimism and unwavering loyalty to Mr. Krabs.
Despite their antagonistic encounters, there are moments of genuine connection between the two. For example, in “F.U.N.,” SpongeBob tries to teach Plankton the value of friendship, resulting in a temporary truce. While Plankton ultimately returns to his scheming ways, this episode hints at his capacity for change and his underlying loneliness.

Despite their bickering, Karen genuinely cares for Plankton and often provides practical solutions to his problems. She’s also the voice of reason, frequently pointing out the flaws in his plans. Their relationship adds a touch of humanity to Plankton’s character, showing that even a villain needs companionship and support.
