Appearances
Plankton was first created by Stephen Hillenburg as a potential villain for the show and was included in his series bible in 1996. However, he later feared that Plankton's stories would get tedious and predictable. During the production of season 1, Hillenburg demoted Plankton from a main character to a minor one; he insisted that Plankton would work better as a one-time guest star.[1] However, Doug Lawrence loved the character. He used his writing and acting skills to prove that Plankton could work as a major antagonist. If Lawrence did not have a dual role as both the voice and writer for Plankton, his character would never have become a major villain.[2]
Interview with Mr. Lawrence about Plankton's origins
Doug Lawrence summarized Plankton's origins in 2015, saying that he "was only supposed to be in one or two episodes, but I was a writer on the show and I really liked this character."[1] Following his first voice recording as Plankton, Lawrence wrote some of his own ideas for the character and passed them to Hillenburg.[1] From then on, Plankton began to appear more often. Lawrence's most notable contribution was giving a personality to Plankton's "waterproof computer," named Karen after Stephen Hillenburg's wife.[3]
Doug Lawrence decided that Plankton and Karen should be an inseparable duo, with Karen as the brains of the operation, always supplying Plankton with evil plans. Lawrence said: "I want more Karen on the show ... The married life of an evil genius is the funniest thing to me, so in that regard [Karen] definitely enhances Plankton’s stories making him more than just your typical bad guy."[4]
Plankton and Karen promoted to the "Main Cast" section.
Doug Lawrence says that Plankton and Karen finally became main characters after the third season. The credits of the 2004 movie were the first time that the SpongeBob franchise ever billed a "Main Cast" in its credits. Both Plankton and Karen were both officially promoted to main characters in the film's credits. Since then, their stories have been one of the show's most popular and important elements. Plankton has also appeared in numerous tie-in books, comics, and video games.
