Plankton Over The Years

Sheldon Joseph Plankton, or Plankton for short, probably went through the least amount of redesigning compared to the other characters, but it's still noticeable by looking at his eyebrow, which was originally much shorter and not as bushy. From top left: Plankton!, Season 1, Season 2, Season 3, The SpongeBob SquarePants Movie, Season 4, Season 5-Season 8, Season 9-Present.
