Role in episode
He is made by Plankton as a way to detect Krabby Patties to the "smallest molecule of a Krabby Patty." This however backfires when Plankton accidentally pushes the switch to start it, accidentally sucking in Plankton. Plankton then goes through the many equipment. The Analyzer outputs that Plankton is made of "30% mean guy," "20% spiteful monster," and "50% evil butt-head," which from here he concludes that the sample is "100% big jerk."
He then praised Karen's new screensaver. Plankton, being fed up with him, had destroyed him with a wrench.
Plankton was previously analyzed as 1% evil 99% hot gas in "Plankton!"
