I recently stumbled upon a hauntingly beautiful Mr. Plankton fic called 'Chitin Hearts' on AO3, and it wrecked me in the best way. The story dives deep into Plankton's isolation, framing his failed schemes as desperate cries for attention rather than pure villainy. It explores his late-night monologues to Karen, where he admits feeling invisible in Bikini Bottom—like a ghost everyone ignores unless he's causing trouble.
The author uses visceral metaphors, comparing him to a discarded shrimp shell washed under the Krusty Krab's dumpster. What got me was the flashback scene of young Plankton being bullied by jellyfish, which recontextualizes his present-day bitterness. The fic doesn't excuse his actions but makes you ache for that tiny speck of loneliness orbiting a world that won't let him in. Another gem is 'Graffiti on the Chum Bucket,' where Plankton secretly admires the Krabby Patty not for its recipe, but because it represents belonging—something he scribbles about in angsty poetry no one reads.
