In putting together this summer's superhero-themed SpongeBob Comics Annual-Size Super-Giant Swimtacular #2, United Plankton Pictures dug deep and left-of-center for inspiration and riff material. How deep, and how left-of-center? Well, the book includes, "I Shall Destroy All The Civilized Planktons!", a rather meticulously assembled homage to the work of Golden Age oddball artist Fletcher Hanks and his Stardust The Super-Wizard, by Paul Karasik and R. Sikoryak.
That story follows a few featuring more traditional targets of parody, like a Western-themed story starring SpongeBob regular Mermaid Man, who is basically just Silver Age Aquaman with sea shells over his nipples and a starfish in the middle of his face, and another in which Squidward becomes Batman parody the Squishy Knight and SpongeBob becomes "Multi-Purpose Sponge, the hero with a different costume in every panel" (which allows for panel after panel of SpongeBob dressed as various Marvel and DC superheroes).
